Its epicenter was near Ometepec, in the border between the states of Guerrero and Oaxaca. With a shallow focus of 20 km, the earthquake caused strong shaking over a large area along the Oaxaca–Guerrero border and the adjacent Pacific coastline. Significant tremors were felt in areas up to several hundred kilometers away, including Mexico City and also in Guatemala. Two people were killed and over 30,000 houses were damaged or destroyed. Tectonic setting The states of Guerrero and Oaxaca lie above the convergent boundary where the Cocos plate is being subducted below the North American plate at a rate of 6.4 cm/yr (2.5 in/yr). The dip of the subducting slab is about 15° as defined by focal mechanisms and hypocenters of previous earthquakes. Seismicity in this area is characterized by regular megathrust earthquakes along the plate interface. In addition, there have been a series of historic normal fault events within the subducting slab.Singh S.K. M. Ordaz L. Alcantara N. Shapiro V. Kostoglodov J. F. Pacheco S. Alcocer C. Gutierrez R.

The United States Geological Survey (USGS) reported the epicenter in the state of Oaxaca, about 23 km east of Ometepec and 6 km northwest of San Juan Cacahuatepec. The depth was reported as 15 km by NSS and 20 km by the USGS.

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. The earthquake coincided with an earthquake drill in Chiapas. The earthquake drill, simulating an earthquake of magnitude 7.9 on the Richter scale, was implemented by the Protección Civil of Chiapas on 20 March. The earthquake drill started at 12:00, and the real earthquake occurred just minutes later.http://www.nortedigital.mx/article.php?id=6881 Sismo en Chiapas coincide con simulacro 25 August 2012 https://archive.today/20130221091417/http://www.nortedigital.mx/article.php?id=6881 21 February 2013 dead Damage thumb|Structural damage caused by the earthquake at the Monterrey Institute of Technology and Higher Education, Mexico City Campus The airport of Mexico City was closed for a short time and reopened after no damage had been observed.https://www.ledevoir.com/international/actualites-internationales/345491/un-seisme-de-magnitude-7-9-frappe-le-mexique Un séisme de magnitude 7,4 frappe le Mexique 20 March 2012 28 December 2016 The trading of Mexican Stock Exchange (BMV) was suspended.
