An earthquake of magnitude 4.4 occurred only 13 minutes ago 32 km northwest of San Francisco del Monte de Oro, Argentina, INPRES reported.
The quake hit at a shallow depth of 10 km beneath the epicenter near San Francisco del Monte de Oro, Departamento de Ayacucho, San Luis, Argentina, in the morning on Friday 25 December 2020 at 9:11 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 European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.4 as well.
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 Francisco del Monte de Oro (pop. 3,300) located 32 km from the epicenter, and Villa General Roca (pop. 200) 40 km away.
