An earthquake of magnitude 4.2 occurred only 21 minutes ago 30 km southwest of Ometepec, Mexico, Mexico's National Seismological Service (SSN) reported.
The quake hit at a moderately shallow depth of 30 km beneath the epicenter near Ometepec, Guerrero, Mexico, early morning on Tuesday 11 May 2021 at 5:18 am local time. 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 San Nicolas (pop. 3,300) located 4 km from the epicenter, Montecillos (pop. 1000) 5 km away, Cuajinicuilapa (pop. 10,300) 9 km away, El Pitahayo (pop. 1,600) 12 km away, Juchitan (pop. 3,300) 28 km away, and Ometepec (pop. 24,100) 30 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, and Pinotepa Nacional (pop. 29,600) 47 km away.
