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.

Based on its magnitude, the fault that was active during the quake ruptured along a surface of approx. 32 km² (=12 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 10 km (6 mi).
Aftershocks typically occur during the days and weeks following the quake at or near the same fault, at distances of up to approx. two times the length of the rupture zone.
The often broadly linear arrangement of aftershock epicenters encompasses the rupture zone of the main shock (check on the map below to verify).
