4.2 quake 25 Apr 2:21 pm (GMT -5)
Mexico's National Seismological Service (SSN) reported a magnitude 4.2 quake in Mexico near Crucecita, Santa María Huatulco, Oaxaca, only 24 minutes ago. The earthquake hit early afternoon on Sunday 25 April 2021 at 2:21 pm local time at a shallow depth of 22 km. 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 Agustin (pop. 250) located 4 km from the epicenter, Crucecita (pop. 15,100) 18 km away, San Isidro Apango (pop. 1000) 18 km away, Huatulco (pop. 7,400) 19 km away, San Miguel Figueroa (pop. 1,100) 19 km away, La Erradura (pop. 1,100) 20 km away, San Pedro Pochutla (pop. 13,700) 23 km away, Puerto Angel (pop. 2,600) 24 km away, and Benito Juarez (pop. 1,300) 24 km away.
