A magnitude 4.6 earthquake near Pinotepa Nacional, Santiago Pinotepa Nacional, Oaxaca, Mexico, was reported only 15 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 10 km beneath the epicenter in the evening on Sunday 20 June 2021 at 8:03 pm 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 4.6 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 24 km from the epicenter, Corralero (pop. 1,700) 28 km away, Santo Domingo Armenta (pop. 2,600) 30 km away, El Ciruelo (pop. 2,200) 31 km away, San Nicolas (pop. 3,300) 43 km away, Pinotepa Nacional (pop. 29,600) 46 km away, Cuajinicuilapa (pop. 10,300) 46 km away, Santiago (pop. 10,100) 63 km away, and Ometepec (pop. 24,100) 70 km away.
