Magnitude 4.9 earthquake strikes near San Martin, Departamento de San Martín, Mendoza, Argentina

A shallow magnitude 4.9 earthquake was reported around noon near San Martin, Departamento de San Martín, Mendoza, Argentina.
According to the German Research Centre for Geosciences (GFZ), the quake hit on Saturday, March 18th, 2023, at 12:41 pm local time at a shallow depth of 10 km. 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.
A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 4.9 earthquake 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 San Martin (pop. 82,500) located 34 km from the epicenter, and Mendoza (pop. 876,900) 69 km away.
