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)
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.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.

Antofagasta Chile (393.4 km W of epicenter) [Map] / Weak shaking (MMI III) / horizontal (sideways) swinging / 10-15 s : The floor moved sideways then stopped and after a few minutes it started moving again but less | 4 users found this interesting.  
  • There has been several deep quakes for decades here in Jujuy and Salta and actually we can't feel them. But it doesn't matter, someday a big one will come, it's inevitable. I guess each hundred years there's one.
  • too many deep quakes are not a good sign, take care there mate
