A magnitude 5.1 earthquake near Coquimbo, Provincia de Elqui, Coquimbo Region, Chile, was reported only 14 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 very shallow depth of 5 km beneath the epicenter early morning on Monday 18 January 2021 at 2:45 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.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Coquimbo (pop. 161,300) located 27 km from the epicenter, and La Serena (pop. 154,500) 37 km away, the quake should have been felt as light shaking.
