5.5 quake 27 Dec 2:11 am (GMT -5)
A magnitude 5.5 earthquake near San Juan de Marcona, Provincia de Nazca, Ica, Peru, was reported only 10 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 early morning on Sunday 27 December 2020 at 2:11 am 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 5.5 earthquake as well.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Atico (pop. 200) located 74 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Coracora (pop. 7,400) located 114 km from the epicenter, San Juan de Marcona (pop. 12,800) 116 km away, Minas de Marcona (pop. 15,500) 123 km away, and Tambo (pop. 5,000) 133 km away.
