An earthquake struck the Mexican state of Oaxaca at 10:29 local time on June 23, 2020, with a magnitude of 7.4 Mw.

Oaxaca is near the Tehuantepec fracture zone, which is where the plates stick together causing frictions leading to earthquakes.

According to the United States Geological Survey (USGS), the epicenter of the earthquake was located 12 kilometers (7.5 mi) south-southwest of Santa María Zapotitlán, Oaxaca, between La Crucecita in the Bahías de Huatulco tourist resort to the southwest and the port of Salina Cruz to the northeast.

Other damaged structures included 213 schools, 15 health centers, three hospitals, 7 bridges and 25 sections of state highways.

[14] Because its tectonic setting leads to frequent earthquakes in Mexico, the Mexican government's response has improved over the years.

The Mexican government sent out a warning about the incoming earthquake with its alert system this allowed the residents to have enough time to get outdoors where it was safe.
