Mexico was shaken near Salina Cruz, Oaxaca, by an earthquake of magnitude 5.0 only 23 minutes ago, Mexico's National Seismological Service (SSN) reported.
The quake hit at a shallow depth of 11 km beneath the epicenter near Salina Cruz, Oaxaca, Mexico, in the morning on Friday 23 April 2021 at 9:33 am local time. 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.
Our monitoring service identified a second report from the United States Geological Survey which listed the quake at magnitude 4.8.
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 91 km from the epicenter, San Francisco del Mar Viejo (pop. 4,000) 96 km away, La Gloria (pop. 1,800) 99 km away, San Mateo del Mar (pop. 5,700) 104 km away, Colonia Juarez (pop. 2,800) 106 km away, Paredon (pop. 6,100) 106 km away, Salina Cruz (pop. 76,600) 112 km away, Tonala (pop. 35,300) 118 km away, and Arriaga (pop. 24,400) 119 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
