Moderate yet deep earthquake of magnitude 5.4 just reported 102 km southeast of Calama, Chile

5.4 quake 10 Dec 3:41 am (GMT -3)

The German Research Centre for Geosciences (GFZ) reported a magnitude 5.4 quake in Chile near Calama, Provincia de El Loa, Antofagasta, only 13 minutes ago. The earthquake hit early morning on Saturday, December 10th, 2022, at 3:41 am local time at an intermediate depth of 119 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.
A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 5.4 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 5.6.
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 San Pedro de Atacama (pop. 2,000) located 22 km from the epicenter, and Calama (pop. 143,100) 102 km away.
