4.2 quake 19 Dec 7:39 pm (GMT -3)
A intermediate to deep magnitude 4.2 earthquake was reported early evening near San Antonio de los Cobres, Departamento de Los Andes, Salta, Argentina.
According to INPRES, the quake hit on Saturday 19 December 2020 at 7:39 pm local time at an intermediate to considerable depth of 221 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 the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.2 earthquake 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, 63 km away), the quake was probably not felt.
