Photos of an excursion to the volcanic site of Sousaki with its strange geology. Even all rocks are alterated by volcanic fluids and gases, it is strange, that one can not really find typical volcanic rocks, like dacites or andesites. There are two caves with dangerous activity of gases like H2S, CO, CO2. (Photo: Tobias Schorr)

La Palma volcano eruption 2021: impressions mid October 2021 (16 Images)

During 5 Oct, activity remained essentially unchanged, but little wind caused lots of ash and dust being in the air in nearby areas. Lava fountaining was reduced compared to earlier on, although ash emissions remained significant and lava flows continued to advance at various fronts. (Photo: Tom Pfeiffer)

La Palma volcano eruption 2021:5 Oct - lava fountains (6 Images)

After the reconfiguration of the vents the day before, caused by repeated collapses of parts of the crater walls, the eruption seemed more stable on 4 Oct. Intense explosive activity continued at decreased level from the vents, with pulsating lava fountains as well as lava effusion from the now breached crater. (Photo: Tom Pfeiffer)

La Palma volcano eruption 2021: 4 Oct - lava fountains and ash (48 Images)

A surge of magma likely caused the northwestern wall of the main crater to collapse, leaving a steep-walled crater valley stretching from the previous summit crater to the area of the former flank vents. (Photo: Tom Pfeiffer)

La Palma volcano eruption 2021: 3 Oct - crater collapse and lava fountains (36 Images)

During 2 Oct, the activity continued without significant changes. At the cone, the flank vents remained active with lava spattering or low fountaining to feed lava flows, while pulsating lava fountaining became again stronger at the summit vents.
The effusive vent north from the cone remained active with quiet lava effusion as well. Favorable wind conditions and a special permit from Guardia Civil provided us with unique observation opportunities from close range. (Photo: Tom Pfeiffer)

La Palma volcano eruption 2021: 2 Oct 2021 - lava flows and fountains (96 Images)

After the opening of a second flank vent on the NW slope of the cone during the previous evening, another effusive vent opened during the night 30 Sep-1 Oct or early on 1 Oct outside the cone, a few 100 m north of it in a depression next to it.
Besides that, activity continued without significant changes with lava fountaining from the various vents at the cone and several active lava flows. (Photo: Tom Pfeiffer)

La Palma volcano eruption 2021: 1 Oct - concentric ash plumes (32 Images)

With a special permit from the Civil Protection, Tom and a few other members of the Volcanological Society were granted short time access to the area in upper El Paraiso close to the vent.
During the day, activity had been at stable levels similar to the previous days, with continuous lava fountains from the flank vent, associated with effusion of several overlapping lava flows, as well as pulsating moderate jets of gas, ash and some lava bombs from the upper vents.
This activity changed short time after we had left in the later evening, with the opening of new vents and new lava flows further to the north of the ones seen here, destroying the places shown or at least making them inaccessible afterwards. (Photo: Tom Pfeiffer)

La Palma volcano eruption 2021: 30 Sep - lava from close (52 Images)

In the late evening of 28 Sep, the main lava flow made a rapid advance to reach the sea and quickly started to build a new delta of land.
At the vents, activity remained more or less the same as during the past days - vigorous liquid lava fountains from the NW flank vent as well as gas- and ash-rich lava fountains from the summit vents. A large surface lava flow from the flank vent remained active and had its front in the area of Todoque. (Photo: Tom Pfeiffer)

La Palma volcano eruption 2021: 29 Sep - lava at the ocean (20 Images)

Activity remained intense throughout the day, with sustained lava fountaining from the flank vent, strong pulsating tall gas-rich fountains from the summit vents and strong lava effusion both into the new flow from the flank vent as well into the main flow, that reached the sea late at night. (Photo: Tom Pfeiffer)

La Palma volcano eruption 2021: 28 Sep - peak of activity (24 Images)

Early on 27 Sep, activity at the vents suddenly ceased completely, at least visually. Sporadic mild ash emissions and explosions restarted to occur around lunch, and became more frequent in the afternoon.
By early evening, the pause of the eruption (which might have been caused by a new intrusion at depth, disturbing the existing pathways) ended, as shown in the following sequence of images: (Photo: Tom Pfeiffer)

La Palma volcano eruption 2021: 27 Sep - eruption pauses and restarts (28 Images)

On 26 Sep, the lava fountaining again increased in height. Typically, the principal summit vent produced tall, candle-like roaring jets that rose to up to 1000 m at times. The flank vent remained moderately active and continued to feed the northern lava flow visible in the pictures below from La Laguna. (Photo: Tom Pfeiffer)

La Palma volcano eruption 2021: 26 Sep - candle-like tall lava fountains (16 Images)

During 25 and 26 Sep, the activity continued with no significant changes - tall lava fountains from the main vents in the cone's summit crater, lava flow emission from the flank vent that had opened on 24 Sep, as well as lava effusion into the main flow presumably through lava tubes.
Compared to 23-24 Sep, the lava fountaining decreased significantly on 26 September morning, only to pick up in the evening again.
The photos were taken from viewpoints to the SW and NW of the vent in the night 25-26 Sep and on 26 Sep morning: (Photo: Tom Pfeiffer)

La Palma volcano eruption 2021: 25-26 Sep - lava fountains and cone growth (24 Images)

Around noon on Sep 24, a series of very strong explosions with shock waves and loud detonations were recorded at the cone; likely this was when the upper conduit inside it became occasionally blocked by large gas bubbles. The increased pressure lead to the opening of two closely spaced vents on the lower NW flank of the cone, from where new lava flows started to erupt.
The opening of these vents was accompanied by the formation of a new collapse crater above the northernmost of the two vents. Similar events were to be repeated in the coming days, and a week later, the flank crater was finally merged with the main crater. The vent at the bottom of this new crater quickly became one of the protagonists of the eruption at that stage: it produced vigorous spattering and was feeding a fast-flowing new surface lava flow that traveled along and enlarged the northern margin of the total lava flow field.
Even with the new effusive activity just tens of meters below, the summit vent continued to produce gas-rich lava fountains from now at least 3 vents close to each other in the summit crater. Initially the height of the fountain seemed to have decreased when the flank vent opened, but later regained in strength again, and continued to reach several hundred meters in height at similar levels as before.
The pictures show the activity from the cone, the lava fountaining and lava effusion from the new flank vent in the evening of 24 Sep. (Photo: Tom Pfeiffer)

La Palma volcano eruption 2021: Sep 24 - new vent opens on cone (36 Images)

The activity remained fairly stable until noon of 24 Sep, characterized by sustained tall (4-500 m or more) lava fountaining, generating an eruption column and ash plume that rose 2-3 km, as well as constant lava effusion from the main vent. The latter formed a channeled surface flow that traveled about 1-2 km west from the vent, while a (probably more significant) part was likely directed into lava tubes feeding the flow field further below, which continued mostly to thicken and spread laterally.
The following pictures mostly show the lava fountain and ash plume from various angles at distances from 3-8 km during the morning of 24 Sep. (Photo: Tom Pfeiffer)

La Palma's active Cumbre Vieja volcano erupted again on 19 Sep 2021, after 50 years of slumber. Tom Pfeiffer and a small group of friends from the Volcanological Society were lucky enough to be able to reach the island on the 4th day of eruption via a Condor flight from Munich.
During 22-23 Sep, the eruption was characterized by near-continuour, rapidly pulsating and moderately tall lava fountains from the main vent, along with large lava bubble explosions and associated shock waves. Lava effusion continued to occur mostly directly into the main lava tube and lava flow, which continued to mostly spread laterally and thicken in the area of Todoque, rather expanding it than pushing its front much forward towards the ocean. This would change in the course of the week...

A powerful Plinian explosive volcanic eruption took place about 13,077 years ago (or at about 11,057 BC) at the Laacher See caldera in the Eifel (western Germany). It was one of Central Europe's largest eruptions during the past 100,000 years and ejected around 20 cubic kilometers of ash and pumice into an eruption column that rose to at least 20 km height, comparable to the Pinatubo eruption in the Philippines in 1991.
The Laacher See is considered dormant today. Signs of volcanic life can be found at the lake shore in form of CO2 emissions.
The products of the eruption 13,000 years ago left thick deposits of pumice and welded ignimbrite, that has been used as building material since Ancient times. Here are some impressions of the area, taken during a series of excursions: (Photo: Tobias Schorr)

Mt Ararat volcano is not only one of the most iconic and largest potentially still active volcanoes in the world, but certainly one that has more connections to history, religion, myths, culture and politics in the Caucasus-Middle East region than any other mountain as well. One of the many beliefs around it refers to the Bible's tale of Noah. According to it, its summit was the first to emerge as new land when the Deluge receded and Noah could land again here, starting to populate the new world...
Even though its location became part of the Turkish state in 1920 following the Turkish-Armenian war and intervention of Russia, it remains an important national symbol of the Armenian people, whose original population area was much larger than today's country, and had Ararat quite in its center. Today, from many points in western Armenia, it remains a mighty background of the scenery.
The pictures were taken during our latest small group tour to Armenia's geological and cultural highlights. (Photo: Tom Pfeiffer)

One of the most remarkable aspects of the Bronze-Age town near Akrotiri on Santorini Island, covered by volcanic ash during the Minoan eruption around 1600 BC and partially excavated since 1956, are a great number of marvelous frescoes that might rank among the most inspiring pieces of art from the 2nd millennium BC, but also provide a unique insight into life and culture at the heyday of the Minoan and Cycladic culture.
Extremely well-made reproductions of the original frescos (which are stored and partially exhibited in both the Archeological museum of Athens and Fira on Santorini) were first presented on Santorini during the 1st International Symposium on the Wall Paintings of Thera in 1997, in beautiful pumice caves and rooms of the Petros M. Nomikos Conference Centre.
The reproductions in this exhibition were marvelously matched with the inspiring architecture of the rooms they are shown, providing a fantastic way to immerse oneself into life of at the time of the eruption in the Bronze Age. Unfortunately this exhibition ended a few years ago. The original frescos are now stored in the National Archaeological Museum in Athens.
Photographer and Santorini expert Tobias Schorr documented this brilliant exhibition: (Photo: Tobias Schorr)

The northeastern Germany's Saarland and adjacient parts of Rheinland-Pfalz are saw very intense volcanic activity in the Permian period, approx. 280 million years ago. Both large-scale magmatic intrusions as well as important volcanic activity on the surface of the back-then desert-like landscapes created important plutonic (intrusive) bodies (such as granites, diorites etc) as well as a vast plateau of lava flows and pyroclastic rocks that covered older sediments (mainly sand- and mudstones).
Today, this layer of magmatic rocks forms a beautiful plateau of small mountains and hills reaching approx. 4-600 m elevation and carved by carved by gentle valleys such as the Nahe valley. The exposed and eroded volcanic and plutonic rocks are rich in a variety of minerals, in particular quartz and agate. Exploration and treatment of these minerals gave rise to an important mineral-cutting industry that flourished for centuries especially in the area around Idar-Oberstein, which became (and in parts still is) a hot-spot for mineral treatment and trade.
During a visit in Aug 2020, Tobias and Tom explored some of the hidden volcanic treasures of the northern Saarland (St. Wendel region). (Photo: Tobias Schorr)

Photographs taken by volcanologist Dr Ingrid Smet when she observed Stromboli’s volcanic activity from 24 to 26 July 2019. During this time span, the volcano remained at a level of higher than usual activity with very frequent Strombolian explosions. Some of these were so strong that at night one could observe the glowing bombs from the village. The lava flows that occurred after the 3 July paroxysm were also still active on the upper parts of the western edge of the Sciara.

The oldest volcanic rocks on Santorini are found in the SW part of the island, in the area of Akrotiri (Loumaravi) complex and near the lighthouse (Cape Akrotiri). They consists dominantly of andesitic and dacitic domes and flows as well as large amounts of mostly fine-grained, silica-rich and bright-in-color submarine volcanic breccia and ashes. Hydrothermal alteration is common, leading to reddish and greenish secondary minerals in the tuffs.
A great way to observe these features is to take the beach shuttle boat from Akrotiri (opposite Nikolas Cave tavern) to the Black Beach via the Red and White Beaches.

Balos is a small bay and beach on the caldera side near Akrotiri. It can be accessed from a trail leading down from the caldera rim above or following the coast, starting at the caldera beach with its access road. Both can be combined to a highly interesting short round trip of about 1-2 hours.
It is one of Santorini's least crowded and best places to swim inside the caldera. Until today, it is also used as a small harbor and boat shelter, as well as a famous place to collect capers. Most likely, the Balos Bay was already used as harbor in Minoan times. Remnants of Minoan building had been found on the cliff above during the 19 and 20th centuries (but unfortunately construction and erosion have by now destroyed most of it).
Geologically, it is also of particular interest: along the coast, the cliffs expose an old basaltic-andesitic cinder cone in cross section where a transition from water-magma interaction (phreatomagmatic activity) to purely strombolian-type eruptions (magmatic activity) is brilliantly recorded.

Before going to Fira for our caldera hike to Oia during our geologic walking tours, we decided to make an additional stop in the traditional village of Vothonas, one of the most scenic and still largely untouched-by-tourism on the island. It is located at the feet of the northern slopes of the Pirgos hill. It had developed from cave-house settlements in the area where several of the large characteristic pumice canyons meet to a form a broad valley. Besides an excellent place to study the traditional cave-house architecture, it offers excellent outcrops of the massive pumice layer from the 1600 BC eruption. (Photo: Tom Pfeiffer)

Normally, our last excursion during the geologic walking tour leads us to the non-volcanic basement, which forms the highest mountain Profitis Ilias and its neighbor Mesa Vouno, where the Ancient Greek city of Thera was located and whose excavated ruins are certainly a highlight that should not be missed during a visit to Santorini.
Spectacular views, very interesting geological formations, and - in spring - extraordinary spring colors by the rich flora, wait for you. (Photo: Tom Pfeiffer)

On one of the days during our geologic walking tours, depending on sea and weather conditions, we take the time to visit the historic volcanic islands of Nea and Palea Kameni in depth. The following shows some impressions from this excursion from 1 May 2019, and includes a dramatic weather display in the afternoon, caused by the arrival of moist warm air masses from Africa. Fortunately, this remained only a visual display and played out entirely high above in the atmosphere without affecting the ground. (Photo: Tom Pfeiffer)

Another excursion during the geologic walking tour is the 12 km hike from Fira to Oia, a classic walk considered one of the best and most scenic hikes in the world and one of particular geologic interest as well. It leads through the elegant streets of Fira, Firostefani, Imerovigli and Oia as well as old mule paths, and for most of the time offers breathtaking views over the northern caldera of Santorini, which was the site where the violent Minoan volcanic eruption around 1600 BC took place and reshaped the island forever.

Normally, our first excursion during the geologic walking tour, we visit the area of the oldest volcanic rocks of Santorini found in the SW peninsula near Akrotiri and the lighthouse. It is a very varied walk along beaches, the caldera, through fields on old, mostly forgotten trails and mule tracks. Geologic highlights include spectacular submarine tuffs and lava domes, often with fantastic hydrothermal alterations. (Photo: Tom Pfeiffer)

Spring in Greece is an explosion of colors, dominated by hundred shades of green and yellows. Meadows full of flowers, silver-green olive groves and the blue sea are everywhere.
One area of particular beauty is the Saronic Gulf which also includes one of Europe's least known active volcanoes, the Methana lava dome complex. The photos presented were taken on 9 and 10 April 2019, following a tour to Methana & the Saronic Gulf. We also arrange private excursions to this highly interesting area, starting in Athens or other places nearby, for 2-4 persons and suggested length of 2-3 days. Please contact us if you are interested! (Photo: Tom Pfeiffer)

In January 2019, magma levels inside Stromboli volcano's conduits rise almost to the rim, producing spectacular activity from several vents. In particular, a large cinder cone has been growing from the NE vent.
The photo shown here illustrate this activity as observed during the evening of 20 Jan 2019. You can find a activity report here.

Expedition leader Galih observed Merapi on 10 Jan and documented the growing lava dome, which is becoming increasingly dangerous, as glowing rockfalls have becoming larger and more frequently, prone to produce pyroclastic flows.
Photos were taken from the south east side of Merapi in around 4 km distance from the crater. (Photo: Galih Jati)

On 17 Oct, explosions were particularly violent at Anak Krakatau. We show a series of images of a spectacular explosion captured from close range by boat. 2 months later, the cone of Anak Krakatau collapsed into the sea on the evening of 22 Dec 2018, triggering a catastrophic tsunami (more info).
Continued activity that accumulated more and more weight on the cone, built on top of a steep underwater slope in the SW (left in the images), and shaking by explosions like this might well have been the final trigger for that tragic event. (Photo: Tom Pfeiffer)

Krakatau volcano (Indonesia) Nov 2018 eruption: a night on the beach (28 Images)

During 20-21 Nov, activity changes significantly: explosions became more rich in ash and contained much less and much less brighter lava bombs. As well, the intervals between individual events gradually increased overall, reaching up to about 2 hours by 22 Nov afternoon although phases of more frequent activity still occurred.
The most likely cause is that the magma column continued to drop internally and thus favored the formation of a more robust blockage, which in turn favored the occurrence of strong vulcanian-style explosions with less fresh incandescent material, but many fragments of the plug. This process is possibly helped at depth by water seeping into the walls of the conduit (so-called phreatomagmatic activity) as the interior pressure dropped.
Visible activity almost completely ceased during the night 22-23 Nov and picked up only again in the afternoon of 24 Nov, when we saw it from the volcano observatory on our way back. (Photo: Tom Pfeiffer)

The activity observed on 19 Nov continued in a more or less similar way during 20 Nov, although the frequency of explosions had decreased to typically 30 seconds to 1-2 minutes. As the size of explosions observed during the 36 hours we had been on the island group did not exceed a certain threshold (ejecting bombs to the sea), a part of our group decided to take the calculated risk and spend some time on a favorable viewing spot behind the forest and near the shore of Anak Krakatau.
When eruptions eventually started to increase significantly, we left.
Disclaimer: visiting such spots during eruptive phases of Krakatau is very risky and you should be aware that no place on the island of Anak Krakatau is safe from bombs - unexpected large explosions can occur with no warning at any time. (Photo: Tom Pfeiffer)

At the end of the paroxysm during 17-19 Nov, we spent several hours on the boat in about 700 m straight-line distance from the crater, to observe near-continuous explosive activity in the afternoon and evening of 19 Nov. It ranged from weak fountaining to mild to strong strombolian explosions with or without significant ash emissions: (Photo: Tom Pfeiffer)

We managed to arrive at Krakatau at the end of a very intense phase of activity between 17-19 Nov, which produced a new lava flow that reached the sea along a 150 m wide stretch on the southern shore of Anak Krakatau. At the time of our arrival, the effusion rate must have stopped just hours before at most, but the flow front was still active: (Photo: Tom Pfeiffer)

Most autumns we organise a 15 days study and walking tour to the volcanoes of Southern Italy, starting in Naples where we visit Vesuvius and the Phlegrean fields before sailing of to the Aeolian islands to explore Lipari, Vulcano and Stromboli before our grand finale on the summit of Mt Etna in Sicily. Besides an unrivaled diversity of volcanic deposits, structures and phenomena this tour also includes many archaeological, relaxing, cultural and gastronomic excursions - combining all the best aspects of southern Italy! Our 12 - 26 October 2018 tour was guided by volcanologist Dr Ingrid Smet who put together the below photo diary of the trip - we hope you enjoy it! (Photo: Ingrid Smet)

The volcano had a large eruption the morning before we arrived, and then remained more or less calm during our stay, with only intense steaming and some minor ash emissions. Glow from the crater and still warm bombs visible on infrared camera were seen during the first night.

The photographs presented here are taken by VolcanoDiscovery team member and geologist Dr Ingrid Smet during one of our 7 days volcano adventures on Hawaii. During a morning excursion on 22 Mar 2018 our small group found a number of active pahoehoe lava flow fronts at the bottom of the pali which they observed and photographed for 3,5 hours.
These lava flows originate from the tube system of the so-called "61g" lava flow episode of Kilauea volcano, which started in late May 2016 and fed an active ocean entry during July 2016 - Nov 2017. In the past 4 months, the lava tube has been producing surface flows of varying size above and on the pali as well as near its base. By mid March 2018 they had advanced enough to allow spectacular observations of active lava flow fronts after a relatively tough hike of ca. 3 hours across the older lava fields.

A small VolcanoDiscovery group was on a 7 days volcano adventure during the 10th anniversary of a continuous active lava lake inside Halema'uma'u crater in Kilauea's summit caldera. Since the reappearance of lava inside Halema'uma'u crater on 19 March 2008 the level of the active lava lake has been fluctuating a lot and is sometimes visible from the Jagger Museum lookout some 1 km away from the vent. There was also lava spattering from gas bubbles exploding through the surface of the lake in mid March 2018. (Photo: Ingrid Smet)

In March 2018, lava continued to flow through the tube system of the so-called "61g" lava flow episode of Kilauea volcano, which had started in late May 2016 and fed an active ocean entry during July 2016 - Nov 2017.
Since then, the lava tube has been producing surface flows of varying size above and on the pali as well as near its base.
The pictures presented here were taken by team member geologist Dr Ingrid Smet during a morning excursion on 16 Mar 2018. They show sluggish surface lava flows, as have been typical for the past weeks in this area near the base of Pulama pali. (Photo: Ingrid Smet)

Methana opposite Athens in the Saronic Gulf of Greece is one of Europe's least known active volcanic areas. The peninsula consists of a group of overlapping prehistoric and one historic (around 238 BC) lava domes that overlie limestone basement.
An underwater eruption occurred off the northern coast in around 1700 AD.
Methana is known for its hot springs and uncrowded, beautiful green rural landscape. Team member photographer Tobias Schorr who has lived more than 10 years in Methana and knows the peninsula better than anyone recently spent countless hours documenting each of the more than 30 lava domes of Methana with his drone from the air. Here are the results: (Photo: Tobias Schorr)

After a pause of 2 days with almost no ash emissions, mild explosive activity resumed on 24 Feb evening (but could not be well observed then due to heavy cloud cover). The lava flow activity continued with little changes, although seemed to decreased gradually during the days were were still there (until 27 Feb):

Mayon started to erupt again in January 2018, producing several lava flows on the southern and southeastern flanks along with frequent episodes of weak to strong lava fountaining and associated ash plumes, as well as pyroclastic flows triggered by collapse of the lava flow fronts.
Since the eruption seemed to be relatively long-lasting, we decided to visit the volcano during 22-27 Feb. Activity had decreased to mostly quiet lava effusion when observed during the first days (22-25 Feb):

Some impressions of our 'Desert, salt and volcanoes' expedition to Erta Ale and Dallol from 13 to 26 January 2018 - all images taken by participant Anastasia Ganuschenko. The new fissure eruption site which opened up on Erta Ale's flank a year before is still very active; now that some of the early lavas cooled down one can get very close to some of the lava lakes and hornitos that are still active. And thanks to the rainfall that finally came after about 4 years of drought the colourful scenery with salt deposits, acid lakes and small geysirs at the hydrothermal site of Dallol was once again looking its best!

Besides the 14-days tour group departures that we organise to this destination from mid November through to mid March we also offer customised tours at chosen dates for small groups and individuals. Please contact us through email for more information on such private expeditions to Erta Ale and Dallol! (Photo: Anastasia)

Upon request we organised a privately guided 3 days geology tour on the island of Santorini from 8 to 10 February 2018 of which tour guide and geologist Dr Ingrid Smet compiled this selection of photographs.
The islands looked very different from summer time when they are overrun by tourists and the heat has dried up most vegetation. Although the weather is of course less sunny and with higher chances of rain and clouds - and strong winds which sometimes result in the cancellation of all flights - it is well worth visiting Santorini in the winter time to take in the unique and quiet atmosphere and see the colourful winter and early spring flowers...

For many years now we organise 8-9 day group tours to Santorini both in autumn and springtime (Fascination Volcano tour) but if you can also contact us for a private multiple day tour at any custom date. (Photo: Ingrid Smet)

During our expedition to Kamchatka in Sep 2017, Gorely was one of the first volcanoes we visited. Thanks to the fact that it is a shield volcano, the climb to its summit is relatively easy, not very steep, but about 10 km to walk (2-3 hours). Views on the landscape along the way and into its various craters are stunning. (Photo: Tom Pfeiffer)

Nisyros island is located in the eastern part of the Aegean Sea next to Turkey. Together with the isles of Kos and Yali, it represents one of the main active volcanic centra in Aegean Sea, along with Santorini and Milos. One of our VolcanoDiscovery tour guides, Ingrid Smet, made a short reconnaissance trip there at the end of September 2017. Judging from her photographs it seems another perfect destination for one of our Volcano Adventures as it offers all the classic ingredients of active volcanic phenomena, interesting culture, authentic traditions, excellent food, beautiful scenery, nice hiking and relaxing beaches!

This photo diary is a compilation of images from different participants on our 12 - 18 April 2017 Kilauea Volcano Special guided by geologist Ingrid Smet. It also includes photographic documentation of the unofficial ´pilot´ extension that the small group undertook afterwards to explore the other sites, nature, wildlife, scenery and gastronomy of the Big Island.

During their stay on Hawaii the Kamukona lava ocean entry that started in July 2016 was still ongoing so that they had the chance to observe this volcanic acitivity from land, on the sea and in the air. They also watched on a different occasions the lava lake inside Halema´uma´u crater inside Kilauea´s summit caldera, which was at such a high level that the lava spattering could be seen from ca 2 km distance. Unfortunately there were no on-land lava break outs that they could get to as was the case for the March 2017 Kilauea Volcano Specials. (Photo: Ingrid Smet)

A selection of photos taken during our Expedition to Erta Ale and Dallol in early February 2017 by participant Stefan Tommasini - Fotografie mit Seele (website). This Danakil expedition was particulary unique: on one hand a new eruptions started at a fissure on Erta Ale´s flank which let to the partial collapse of the active craters in the summit caldera; on the other hand it was pouring with rain when our group was at Dallol, which is known to be the hottest and driest place on earth... The rain however intensified the colours and activity at Dallol´s hydrothermal deposits, and the flank eruption created a vast lava field with multiple lava lakes and pahoehoe flows. (You can find a short overview of the 2017 flank eruption and Erta Ale volcanic activity update at the end of June 2017 through this link) (c)

$A selection of photographs taken by Ingrid Smet during our June 2017 Nyiragongo lava lake and mountain gorillas expedition in the DR Congo which included a 3 days / nights stay on Nyiragongo volcano. On 6 June the group completed their hike to the summit in dry weather (the people coming up in the next two days were not so lucky) but had to wait a few hours for a first glance onto the red hot lava lake until the clouds around the stratovolcano´s summit and the thick volcanic gasses inside the caldera had temporarily lifted. The next 2 days (7 and 8 June) visibility into the caldera was usually best in the mornings and at intervals during the night, with more clear circumstances in the early morning and right through to dawn and sunrise on the 8th of June. The world´s largest lava lake (about 220 m across) is situated some 400 m below the rim of Nyiragongo´s summit caldera (a diameter of 1.2 km). When visible, the surface of the active lava lake was continuously in motion as exploding gas bubbles create small degassing fountains that recycle the cold black crust back into the red hot liquid lava. Strong degassing also occurred from the edges of the lava lake, the 2016 hornito and along the southern fracture zone. (Photo: Ingrid Smet)$

During the first part of June, activity at Stromboli volcano was one of the most intense periods during several years. At most times, up to 6 or 7 vents were active, most notably the two eastern vents, closely followed and sometimes surpassed by the two western vents.
The following pictures were taken on 9, 11, and 16 June, from various viewpoints and give an idea of this activity.

After a relatively rainy winter 2016/17, spring on the Greek islands was fantastic! Santorini, one of the most famous islands of the Cyclades, was no exception and offered a paradise for photographers: flowers and green everywhere, with the blue and white of the traditional houses and chapels. The following photos were taken during our Santorini photo tour in April 2017.

For almost 3 months in early 2017, Kilauea volcano was the site of one of the most spectacular and rarest volcanic phenomena: a "fire hose" or lava hose shooting into the ocean. A major bench and cliff collapse on New Year 's Eve 2016 exposed the main active lava tube which had been feeding the ocean entry at rates of up to several cubic meters of very fluid, hot (approx. 1200 deg C) lava. The lava has been traveling underground from the vent on the east rift zone to the coast at 10 miles distance.
The collapse on 31 Dec also affected the submarine part of the coast, creating a very steep submarine slope. It took almost 3 months before the continuous addition of lava finally succeeded to create a new lava delta (bench), allowing the lava to encase itself, stopping the "fire hose" effect.
The pictures on the lower part of this page show one of the last days of the life of the fire hose (18 Mar) when a surge in the tube caused it to be particularly violent. (Photo: Tom Pfeiffer)

When hot, liquid lava at temperatures near 1200 deg C, directly coming from the lava tube, meets its arch-enemy water, the reaction is often violent: a battle of elements, generating ever-changing (so-called littoral) explosions in a chaos of steam, fragmented lava pieces which become new black sand, and colors.
The pictures were taken during 12-18 March from several viewpoints on water and on land. Among hundreds of similar photos, it was impossible to choose only a few, even though they cannot even come close to the fascination of watching it from relatively close. Few sights have impressed and mesmerized me as much as this battle between Pele and her sister Nā-maka-o-Kahaʻi, goddess of the sea. (Photo: Tom Pfeiffer)

Impressions from a morning boat tour to the Kamokuna ocean entry on 13 March 2017 during our latest Kilauea Volcano Special tour. We were lucky enough to be there during the last week when the spectacular fire hose was still active.

A special thanks goes to the competent and friendly crew from Kalapana Cultural Tours, in particular to captains Ikaika and Andrew, who we think provide the best service by far among the competition! (Photo: Tom Pfeiffer)

Paul Reichert who took part in one of our latest Volcano Specials in January 2017 was lucky to witness one of Erta Ale volcano's most spectacular and intense eruptive phases in decades.
A surge of magma from depth (probably a small rifting episode) caused the lava lake in the southern pit crater of the caldera to overflow, build up a broad shield, before it collapsed, following the draining of the lake through a system of flank fissures 2-4 km downhill from 21 Jan - a mere day after Paul and his group had left.
The following is a selection of pictures of Paul, in approximate chronological order and annotated using the valuable field reports by Richard and our geologist expedition leader Enku who, along with Paul, were lucky enough to see this once-in-a-lifetime event. A big thank you goes to all of the three for sharing their information and images!

On 11 July 2015, a large dome collapse triggered the second largest block and ash pyroclastic flow of the 21st century (surpassed by Merapi in 2010 only), filling and devastating the Montitlán river valley on Colima's south side to a length of about 10 km.
We visited the deposit approx. 16 months later, in Nov 2016 (compare these to photos taken few days after it was deposited). This fresh, the deposit is a fantastic geologic showcase. It provides extremely interesting insights into the dynamics of this kind of pyroclastic density currents and its origin: (Photo: Tom Pfeiffer)

The first of our Danakil expeditions of the 2016-2017 winter season turned out to be an unexpected success - not only because of the flawless logistics and organisation or the friendliness with which local Ethiopians welcome international travelers, but also thanks to the very high activity at Erta Ale and Dallol!
At Erta Ale, the lava lake has been overflowing multiple times a day, sometimes even continuously, constructing a large new area of fresh pahoehoe lava flows on the caldera floor. Our main guide and organiser, Ethiopian geologist Enku, has been regularly visiting this location but never saw it this active and impressive in his 20 years experience.
And also Dallol seems to have stepped up its game: after the slow drying out and shrinking of the hydrothermal activity at this unique location between 2010 and 2015, last year´s rains had transformed it back to is former colourful and fascinating self - and this active area is still growing even in the past few weeks.
Below we gladly share with you a number of images that our participants Hans en Jooske kindly send us days after returning home from their Danakil volcano adventure. (Photo: Hans and Jooske)

During our recent Volcano Special during 18-22 Nov, we observed the activity of Colima volcano from close:
It was characterized by the continued weak extrusion of a viscous lava flow from the active, flat summit lava dome (see aerial photos). Explosive activity was only minor and limited to mostly small events at irregular intervals (often more than few hours), but fluctuated noticeably from day to day. (Photo: Tom Pfeiffer)

During our Volcano Special tour to Colima last week, Ingrid and other 3 participants took a scenic overflight in a small charter plane in order to have a closer look at the active lava dome and its viscous flow on the southern flank. A selection of aerial photos from various angles taking while circling the volcano several times at different altitudes is shown. (Photo: Ingrid Smet)

Life returns slowly after destruction by lava flows. In this area, 30 years ago, there was dense rain forest until it was invaded by lava flows from the early stages of the Pu'u 'O'o rift zone eruption.
Dead, half-burnt tree trunks and branches still lie around, some having left molds in the lava.
Among the first plants to colonize the barren lava desert are small ferns whose green stands out from the dark or silvery pahoehoe textures. (Photo: Tom Pfeiffer)

A second boat tour in the morning of 14 Sep resulted in spectacular views of the numerous lava flows entering the sea thanks to exceptionally good wind conditions - southerly winds pushed the heavy steam plume inland.

Active lava breakouts were present about 2 km inland in the coastal flat in mid September 2016. Although the sea entry was the main attraction, a short hike to these flows was a welcome break. (Photo: Tom Pfeiffer)
