An earthquake of magnitude 4.3 occurred around noon on Tuesday 29 December 2020 at 1:29 pm local time near San Antonio de los Cobres, Departamento de Los Andes, Salta, Argentina, as reported by the European-Mediterranean Seismological Centre (EMSC).
According to preliminary data, the quake was located at an intermediate to considerable depth of 209 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.
A second report was later issued by INPRES, which listed it as a magnitude 3.7 earthquake. A third agency, the United States Geological Survey (USGS), reported the same quake at magnitude 4.3.
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, 85 km away), the quake was probably not felt.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
