4.5 quake 24 Mar 8:51 pm (GMT -6)
A shallow magnitude 4.5 earthquake was reported in the evening near Pinotepa Nacional, Santiago Pinotepa Nacional, Oaxaca, Mexico.
According to Mexico's National Seismological Service (SSN), the quake hit on Wednesday 24 March 2021 at 8:51 pm 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. 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.5 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 Callejon de Romulo (pop. 490) located 19 km from the epicenter, Santo Domingo Armenta (pop. 2,600) 25 km away, Corralero (pop. 1,700) 26 km away, El Ciruelo (pop. 2,200) 27 km away, San Nicolas (pop. 3,300) 37 km away, Cuajinicuilapa (pop. 10,300) 41 km away, Pinotepa Nacional (pop. 29,600) 44 km away, and Jamiltepec (pop. 10,100) 63 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Ometepec (pop. 24,100) located 65 km from the epicenter.
