Moderate magnitude 4.4 quake hits 66 km west of San Antonio de los Cobres, Argentina in the afternoon
4.4 quake 20 Dec 4:12 pm (GMT -3)

An earthquake of magnitude 4.4 occurred in the afternoon on Monday, December 20th, 2021, at 4:12 pm local time near San Antonio de los Cobres, Departamento de Los Andes, Salta, Argentina, as reported by the German Research Centre for Geosciences (GFZ).
According to preliminary data, the quake was located at an intermediate to considerable depth of 191 km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. 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.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In San Antonio de los Cobres (pop. 4,000, 66 km away), the quake was probably not felt.
