A magnitude 4.8 earthquake near Concepcion, Provincia de Concepción, Region del Biobio, Chile, was reported only 15 minutes ago by the European-Mediterranean Seismological Centre (EMSC), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a shallow depth of 15 km beneath the epicenter in the afternoon on Wednesday, November 24th, 2021, at 5:03 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 German Research Centre for Geosciences (GFZ), which listed it as a magnitude 4.9 earthquake.
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 Talcahuano (pop. 253,000) located 74 km from the epicenter, Tomé (pop. 46,700) 83 km away, Concepcion (pop. 215,400) 84 km away, Penco (pop. 46,100) 84 km away, Chiguayante (pop. 82,500) 92 km away, and Coronel (pop. 92,900) 92 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Lota (pop. 49,800) located 96 km from the epicenter.
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.
