A major, magnitude 7.1 earthquake hit Mexico late yesterday, September 19. Particularly hard hit was the Puebla region.

Preliminary analysis of the event indices the epicenter was approcimately 58 km SW of Puebla de Zaragoza, Mexico, a city of nearly 3 million, at a depth of approximately 50 km. Reports suggest many buildings in Puebla were damaged, with many collapses. 200 fatalities have been reported so far, however, the number may rise significantly.

Preliminary fault plane solutions (i.e. earthquake mechanism) indicates the main shock happened on a normal fault and is not directly related with the September 8 magnitude 8.1 earthquake.
