A magnitude 4.3 earthquake near Crucecita, Santa María Huatulco, Oaxaca, Mexico, was reported only 21 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 17 km beneath the epicenter in the morning on Sunday 20 June 2021 at 8:29 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 4.3 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 San Agustin (pop. 250) located 37 km from the epicenter, and Crucecita (pop. 15,100) 39 km away.
