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.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Huatulco (pop. 7,400) located 55 km from the epicenter, San Miguel Figueroa (pop. 1,100) 57 km away, Puerto Angel (pop. 2,600) 57 km away, San Pedro Pochutla (pop. 13,700) 60 km away, Benito Juarez (pop. 1,300) 60 km away, San Roque (pop. 1,500) 62 km away, and Merced del Potrero (pop. 2,200) 68 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
