Magnitude 4.2 earthquake strikes near Abra Pampa, Departamento de Cochinoca, Jujuy, Argentina

4.2 quake 19 Jan 8:56 pm (GMT -3)
A intermediate to deep magnitude 4.2 earthquake was reported in the evening near Abra Pampa, Departamento de Cochinoca, Jujuy, Argentina.
According to the United States Geological Survey (USGS), the quake hit on Tuesday 19 January 2021 at 8:56 pm local time at an intermediate to considerable depth of 279.3 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. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
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 Abra Pampa (pop. 9,400, 80 km away), and El Aguilar (pop. 3,700, 82 km away), the quake was probably not felt.
