In September 1985, a magnitude 8.0 earthquake killed an estimated 9,500 people in and around Mexico City. Buildings of 5 to 15 stories were most affected, as their interaction with the shock waves created a harmonic resonance, exacerbating the degree of swaying.  There are several instances of tall buildings in Mexico City incorporating earthquake-resistant engineering. Corrections? Coastal and most inland damage was moderated by the fact that most of the west of Mexico sits on bedrock, which serves to transmit the shockwaves without amplifying them.  The Cocos Plate pushes against and slides under the North American Plate, primarily along the coasts of the states of Michoacán and Guerrero in Mexico.  The Museo Mural Diego Rivera on the north side of the park houses a mural by Diego Rivera which was originally housed in the huge Hotel Del Prado across the street.

In Los Angeles, where the period of the seismic waves was less…, …amplified the effects of the 1985 earthquake, the epicentre of which was located hundreds of miles away. , The stepping-in of non-PRI organizations to take over where the government could not, also took its toll on PRI's reputation.
