5.0 quake 19 May 12:06 pm (GMT -3)
An earthquake of magnitude 5.0 occurred around noon on Wednesday 19 May 2021 at 12:06 pm local time near Añatuya, Departamento de General Taboada, Santiago del Estero, Argentina, as reported by the German Research Centre for Geosciences (GFZ).
According to preliminary data, the quake was located at a great depth of 603 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.
