According to the
National Seismological Service (NSS) of Mexico, the
epicenter was located in the Oaxaca-Guerrero border, about 30 km south of Ometepec and 8 km southeast of
Cuajinicuilapa. The focal mechanism and depth of the earthquake indicate that it was a result of
thrust faulting along or close to the plate interface. Similar earthquakes have struck the area before, including the
1932 Jalisco earthquake, the
1985 Mexico City earthquake, the
1995 Colima–Jalisco earthquake and the
2003 Colima earthquake.
Damage , Mexico City Campus The airport of Mexico City was closed for a short time and reopened after no damage had been observed. The trading of
Mexican Stock Exchange (BMV) was suspended. On 22 March it was announced that two people were killed in Cuajinicuilapa because of the earthquake, one direct and one indirect. The first died due to the injuries caused after a wall collapsed on him in El Tamale community, while the second suffered a heart attack, in San Nicolás. The strongest ground motions registered at very strong (MM VII) on the
Mercalli intensity scale, affecting smaller cities and towns near the epicenter such as
San Juan Cacahuatepec, Cuajinicuilapa,
Ometepec and
Pinotepa Nacional. Many other areas in the states of Guerrero and Oaxaca experienced strong (MM VI) shaking, while larger cities—such as
Huajuapan de León, Oaxaca,
Tehuacán, Puebla, and
Acapulco, Guerrero—experienced moderate (MM V) tremors. Lighter ground motions(MM IV–III)spread through much of south-central Mexico. The intensity in Mexico City was MM VI–VII, which was stronger than the surrounding area because of local topography and soil conditions. Part of a pedestrian bridge collapsed on a small passenger bus in
Azcapotzalco, Mexico City, with no injuries reported. The service of Mexico City Metro Line A was interrupted because of track damage.
