A magnitude 4.6 earthquake near Juchitan de Zaragoza, Heroica Ciudad de Juchitán de Zaragoza, Oaxaca, Mexico, was reported only 17 minutes ago by the German Research Centre for Geosciences (GFZ), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a shallow depth of 10 km beneath the epicenter in the morning on Friday 23 April 2021 at 9:33 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 5.0 earthquake.
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 Portillo Guayaba (pop. 10) located 33 km from the epicenter, Chahuite (pop. 9,800) 49 km away, Las Amilpas (pop. 8,800) 49 km away, and Arriaga (pop. 24,400) 68 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Tonala (pop. 35,300) located 77 km from the epicenter, Juchitan de Zaragoza (pop. 74,800) 81 km away, Salina Cruz (pop. 76,600) 82 km away, Santo Domingo Tehuantepec (pop. 42,100) 93 km away, and Ixtepec (pop. 25,400) 97 km away.
