The German Research Centre for Geosciences (GFZ) reported a magnitude 4.8 quake in Chile near Calama, Provincia de El Loa, Antofagasta, only 10 minutes ago. The earthquake hit in the morning on Friday 7 May 2021 at 11:01 am local time at an intermediate depth of 113 km. 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.9.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Calama (pop. 143,100) located 63 km from the epicenter, and San Pedro de Atacama (pop. 2,000) 114 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.
