4.7 quake 20 Dec 10:55 am (GMT -5)
Just 23 minutes ago, a 4.7-magnitude earthquake struck near Atico, Provincia de Caraveli, Arequipa, Peru. The tremor was recorded in the morning on Sunday 20 December 2020 at 10:55 am local time, at a moderately shallow depth of 48 km below the surface.
The event was filed by the European-Mediterranean Seismological Centre (EMSC), the first seismological agency to report it.
Our monitoring service identified a second report from the German Research Centre for Geosciences (GFZ) which listed the quake at magnitude 4.5.
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 Atico (pop. 200) located 33 km from the epicenter, and Cerro de Arena (pop. 12) 47 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Camana (pop. 16,400) located 112 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.
