Moderate magnitude 4.8 earthquake 100 km northwest of Aparri, Philippines
4.8 quake 17 May 4:42 pm (GMT +8)
4.8 quake 17 May 4:42 pm (GMT +8)
An earthquake of magnitude 4.8 occurred only 15 minutes ago 100 km northwest of Aparri, Philippines, the German Research Centre for Geosciences (GFZ) reported.
The quake hit at a shallow depth of 10 km beneath the epicenter near Aparri, Cagayan, Cagayan Valley, Philippines, in the afternoon on Tuesday, May 17th, 2022, at 4:42 pm local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the Philippine Institute of Volcanology and Seismology (PHIVOLCS), which listed it as a magnitude 5.4 earthquake. Other agencies reporting the same quake include the citizen-seismograph network of RaspberryShake at magnitude 4.8, and the European-Mediterranean Seismological Centre (EMSC) at magnitude 5.0.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Claveria (pop. 10,600) located 53 km from the epicenter, Namuac (pop. 3,000) 53 km away, Pagudpud (pop. 4,900) 65 km away, Cabaritan East (pop. 9,300) 85 km away, and Ballesteros (pop. 5,600) 87 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Pasuquin (pop. 5,800) located 96 km from the epicenter, Aparri (pop. 33,200) 100 km away, and Laoag (pop. 102,100) 111 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
