4.2 quake 1 Dec 9:51 am (GMT -7)
A magnitude 4.2 earthquake near Pinotepa Nacional was reported 33 minutes ago by Mexico's National Seismological Service (SSN), considered the main national agency that monitors seismic activity in Mexico. The earthquake occurred at a shallow depth of 12 km beneath the epicenter in the morning on Tuesday 1 December 2020 at 9.51 am local time. 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 European-Mediterranean Seismological Centre (EMSC) 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 Tuza (pop. 250) located 37 km from the epicenter, and El Azufre (pop. 520) 42 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Corralero (pop. 1,700) located 42 km from the epicenter, El Ciruelo (pop. 2,200) 52 km away, Pinotepa Nacional (pop. 29,600) 54 km away, Santiago (pop. 10,100) 58 km away, Pinotepa de Don Luis (pop. 5,500) 66 km away, and Cuajinicuilapa (pop. 9,400) 74 km away.
