Moderate magnitude 4.2 earthquake 67 km northeast of Tacna, Peru
4.2 quake 16 May 8:28 am (GMT -5)
4.2 quake 16 May 8:28 am (GMT -5)
A shallow magnitude 4.2 earthquake was reported in the morning near Tacna, Provincia de Tacna, Peru.
According to the European-Mediterranean Seismological Centre (EMSC), the quake hit on Sunday 16 May 2021 at 8:28 am 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. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
Our monitoring service identified a second report from the United States Geological Survey which listed the quake at magnitude 4.2 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 Talabaya (pop. 250) located 12 km from the epicenter, Chuquitira (pop. 4,200) 32 km away, and Chipispaya (pop. 1,900) 36 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Quilahuani (pop. 3,200) located 47 km from the epicenter, Tacna (pop. 280,100) 67 km away, and Ilabaya (pop. 9,500) 68 km away.

Data for the same earthquake reported by different agencies

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.
