It had a moment magnitude of 6.7 Mw and an epicenter in the Acambay grabenc, 100 km (62 mi) northwest of Mexico City.
The earthquake occurred along three fault zones that bound the Acambay graben, an extensional tectonic feature located within the Trans-Mexican Volcanic Belt.
The largest vertical displacement, 50 cm (20 in), occurred near Tixmadejé village, about midpoint along the rupture between Acambay and San José Solís.
East of the reservoir, a northwest–southeast trending rupture, likely an extension of the Acambay–Tixmadejé Fault, stretched 2 km (1.2 mi) with vertical displacements of 12–20 cm (4.7–7.9 in).
On the Pastores Fault, a 17 km (11 mi) rupture trending east–west occurred between Santiago Coachochitlán and Mayé el Fresno.
Within the graben, three parallel ruptures were recorded near Temascalcingo, corresponding to the intragraben fault zone, with the longest extending 20 km (12 mi).
