Moderate mag. 4.3 earthquake - South Pacific Ocean, 128 km north of Concepcion, Region del Biobio, Chile, on Saturday, May 14, 2022 at 12:07 am (GMT -5) -

An earthquake of magnitude 4.5 occurred after midnight on Saturday, May 14th, 2022, at 12:07 am local time near Constitucion, Talca, Maule Region, Chile, as reported by the citizen-seismograph network of RaspberryShake.
According to preliminary data, the quake was located at a very shallow depth of 5 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.4 earthquake.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Quirihue (pop. 8,000) located 95 km from the epicenter, Cauquenes (pop. 31,400) 98 km away, Constitucion (pop. 37,900) 99 km away, Tomé (pop. 46,700) 103 km away, and Talcahuano (pop. 253,000) 111 km away.
