Magnitude 5.2 earthquake strikes near Calama, Provincia de El Loa, Antofagasta, Chile

5.2 quake 4 Oct 10:08 am (GMT -3)
5.2 quake 4 Oct 10:08 am (GMT -3)
A magnitude 5.2 earthquake near Calama, Provincia de El Loa, Antofagasta, 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 an intermediate depth of 138 km beneath the epicenter in the morning on Tuesday, October 4th, 2022, at 10:08 am 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.
Our monitoring service identified a second report from the citizen-seismograph network of RaspberryShake which listed the quake at magnitude 5.1. A third agency, the German Research Centre for Geosciences (GFZ), reported the same quake at magnitude 5.1.
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 Calama (pop. 143,100) located 23 km from the epicenter, and Maria Elena (pop. 4,900) 64 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include San Pedro de Atacama (pop. 2,000) located 111 km from the epicenter, and Tocopilla (pop. 24,500) 121 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.
