Moderate earthquake of magnitude 4.2 just reported 31 km southwest of Ometepec, Mexico

4.2 quake 22 Mar 12:43 am (GMT -6)
A shallow magnitude 4.2 earthquake was reported after midnight near Ometepec, Guerrero, Mexico.
According to Mexico's National Seismological Service (SSN), the quake hit on Monday 22 March 2021 at 12:43 am local time at a shallow depth of 27 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 4.2 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 Montecillos (pop. 1000) located 4 km from the epicenter, San Nicolas (pop. 3,300) 4 km away, Cuajinicuilapa (pop. 10,300) 9 km away, El Pitahayo (pop. 1,600) 13 km away, and Ometepec (pop. 24,100) 31 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Marquelia (pop. 6,600) located 40 km from the epicenter, Pinotepa Nacional (pop. 29,600) 46 km away, and Ayutla de los Libres (pop. 15,400) 89 km away.
