A 7.4 magnitude earthquake struck southern Mexico

A 7.4 magnitude earthquake struck southern Mexico
Officials said the 7.4-magnitude earthquake, which struck the southern coast of Mexico on Tuesday, toppled and evacuated buildings, killing at least five people.

The earthquake struck at 10:29 am. Local time (11:29 pm ET), is 6.8 miles with an epicenter southwest of Santa Maria Japotitlan in the state of Oaxaca near O Koyaka.

According to the coordinator of Mexico's National Civil Defense Service, at least five people died.

Oaxaca State Governor Alejandro Murat said a 22-year-old woman and man were among the dead.

Oaxaca Health Services reported earthquake damage in general hospitals in Pocheutla, Puerto Escondido, and some community hospitals in Pinotepa National and other areas. According to Murat, two of the damaged hospitals are working with coronovirus patients.

"We are confirming [the loss] because this hospital is also treating Kovid cases on the Oaxaca coast," he said in an interview with Radio Formula. The severity of the damage is not specified.

The National Civil Defense Service reported the first death after an earthquake collapsed after the earthquake, just east of the popular tourist destination of Hutalco.

Authorities reported a power outage in the entire state capital and damage to the exterior of a hospital in Oaxaca.

Earthquakes can be felt as far as Guatemala, Honduras and El Salvador. In the capital, Mexico City, about 190 miles north of the earthquake, shocks and sirens were heard.

Tsunami waves of 0.68 m (2.2 ft) were observed in Acapulco and 0.71 m (2.3 ft) in the Salina cruise. According to the United States Tsunami Warning System, earlier tsunami warnings were revised downward, forecasting possible waves of one meter (3.3 ft).

According to the Shakeap of the US Geological Survey (USGS), the loss in Oaxaca is considered moderate to moderate.

Estimates modeled by the USGS suggest potential victims and localized damage are possible, but the damage is likely to result in fewer than 100 deaths and less than $ 100 million. However, the model only includes seismic shocks and there is no effect of a possible tsunami on the coast.

The USGS said recent earthquakes in the region have caused secondary hazards such as tsunamis and landslides.

Previous estimates have predicted the earthquake to be 7.7, but it has been revised to 7.4 (and additional modifications are possible).

Mexico is one of the most active seismic zones in the world and has a long history of devastating earthquakes. The country sits atop three large tectonic plates, and its movement leads to regular earthquakes and occasional volcanic eruptions.

In 2017, two powerful earthquakes tore down buildings in the country in two weeks, breaking roads, and killing hundreds of people. One had an intensity of 7.1 and the other an intensity of 8.1.

Mexico City is particularly vulnerable to earthquakes because its very soft and moist soil is shaken and prone to liquefaction, in which the dirt becomes a dense liquid when sufficiently shaken.
