A very shallow magnitude 4.2 earthquake was reported early afternoon near Juchitan de Zaragoza, Heroica Ciudad de Juchitán de Zaragoza, Oaxaca, Mexico.
According to Mexico's National Seismological Service (SSN), the quake hit on Thursday 29 April 2021 at 3:21 pm local time at a very shallow depth of 3 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 4.2 earthquake as well.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Colonia Deportivo (pop. 13) located 4 km from the epicenter, and San Pedro Comitancillo (pop. 3,900) 8 km away, the quake should have been felt as light shaking.

Weak shaking might have been felt in Ixtepec (pop. 25,400) located 16 km from the epicenter, San Blas Atempa (pop. 12,000) 17 km away, Santo Domingo Tehuantepec (pop. 42,100) 17 km away, Juchitan de Zaragoza (pop. 74,800) 23 km away, and Salina Cruz (pop. 76,600) 34 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Matias Romero (pop. 18,900) located 49 km from the epicenter.
