Abstract:

A major industrial area and two power plants are near the epicenter of the Magnitude 8. 1 Mexico Earthquake of September 19, 1985. All investigated facilities are modern, generally well constructed, and included some seismic consideration in their designs. The power plants are founded on rock and firm soils and performed exceptionally well. Much of the industrial area is situated on river deposit sediments, and higher ground motion and certain foundation failures led to various significant earthquake effects. The observations of the performance of facilities and available ground motion records provide insight to the expected performance of modern power and industrial facilities.
