On September 19, 1985, the center, South and West regions of Mexico, in particular the Federal District, were struck by a powerful earthquake, considered the most lethal in Mexican written history. Conmemorating the event 29 year later, the Secretary for Civil Protection of Federal District organized an earthquake drill, for the population to know how to act in these events. The people participated massively, in the capital and in other cities of the country.
