Mexico's National Seismological Service (SSN) reported a magnitude 4.3 quake in Mexico near Pinotepa Nacional, Santiago Pinotepa Nacional, Oaxaca, 36 minutes ago. The earthquake hit in the morning on Thursday 4 March 2021 at 7:50 am local time at a shallow depth of 17 km. 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 4.3 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 Tecoyame (pop. 250) located 41 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Santiago Tepextla (pop. 1,400) located 47 km from the epicenter, Santo Domingo Armenta (pop. 2,600) 51 km away, San Nicolas (pop. 3,300) 51 km away, El Ciruelo (pop. 2,200) 60 km away, Corralero (pop. 1,700) 61 km away, Cuajinicuilapa (pop. 10,300) 62 km away, Marquelia (pop. 6,600) 67 km away, and Pinotepa Nacional (pop. 29,600) 79 km away.
