Significant magnitude 5.0 quake hits 79 km west of Villa General Roca, Argentina in the morning

5.0 quake 11 Jun 10:40 am (GMT -3)

Argentina was shaken near Villa General Roca, Departamento de Belgrano, San Luis, by an earthquake of magnitude 5.0 only 8 minutes ago, the German Research Centre for Geosciences (GFZ) reported.
The quake hit at a shallow depth of 10 km beneath the epicenter near Villa General Roca, Departamento de Belgrano, San Luis, Argentina, in the morning on Saturday, June 11th, 2022, at 10:40 am local time. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 5.0 as well.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Villa General Roca (pop. 200) located 79 km from the epicenter, and San Luis (pop. 184,000) 121 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
