Significant magnitude 5.2 quake hits 79 km southwest of Mollendo, Peru in the evening

A magnitude 5.2 earthquake near Mollendo, Provincia de Islay, Arequipa, Peru, was reported only 11 minutes ago by the German Research Centre for Geosciences (GFZ), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a shallow depth of 10 km beneath the epicenter in the evening on Saturday 27 February 2021 at 9:16 pm local time. 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 European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 5.3 earthquake.
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 Islay (Matarani) (pop. 4,800) located 77 km from the epicenter, Mollendo (pop. 29,000) 79 km away, Cocachacra (pop. 8,800) 93 km away, Camana (pop. 16,400) 112 km away, and Ilo (pop. 53,500) 118 km away.
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.
