4.8 quake 25 km northwest of Tacna, Peru, 18 Apr 7:27 pm (GMT -5)
An earthquake of magnitude 4.8 occurred early evening on Sunday 18 April 2021 at 7:27 pm local time near Tacna, Provincia de Tacna, Peru, as reported by the German Research Centre for Geosciences (GFZ).
According to preliminary data, the quake was located 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 European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 5.0 earthquake.
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 Yarahuay (pop. 16) located 12 km from the epicenter, and Tacna (pop. 280,100) 25 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Chipispaya (pop. 1,900) located 40 km from the epicenter, Ilabaya (pop. 9,500) 47 km away, Quilahuani (pop. 3,200) 57 km away, Chuquitira (pop. 4,200) 69 km away, San Antonio (pop. 15,600) 89 km away, and Moquegua (pop. 54,500) 91 km away.
