The National Seismological Center of the University of Chile reported a magnitude 4.7 quake in Chile near Illapel, Provincia de Choapa, Coquimbo Region, only 30 minutes ago. The earthquake hit in the morning on Thursday 24 December 2020 at 9:15 am local time at a moderately shallow depth of 49.2 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 INPRES, which listed it as a magnitude 5.0 earthquake. Other agencies reporting the same quake include United States Geological Survey (USGS) at magnitude 4.6, European-Mediterranean Seismological Centre (EMSC) at magnitude 4.6, and German Research Centre for Geosciences (GFZ) at magnitude 4.9.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Illapel (pop. 22,800) located 82 km from the epicenter, and Salamanca (pop. 13,300) 105 km away.
