Moderate yet deep earthquake of magnitude 5.2 just reported 77 km northwest of San Antonio de los Cobres, Argentina
5.2 quake 22 Mar 12:18 pm (GMT -3)
An earthquake of magnitude 5.2 occurred around noon on Wednesday, March 22nd, 2023, at 12:18 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 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.
Our monitoring service identified a second report from the citizen-seismograph network of RaspberryShake which listed the quake at magnitude 5.2 as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include San Antonio de los Cobres (pop. 4,000) located 77 km from the epicenter.
