 Talk Summary

The coast of Central Chile experienced a shallow M_w 8.8 earthquake that was associated with strong intensity motion over a 70 mile by 400 mile long corridor similar to the corridor from the coastal region from Los Angeles to San Francisco and the San Joaquin Valley. This earthquake hit at the heart of most industrialized and populated area of Chile.  About 6 million people live in this area.  This area has around 10,000 buildings, with a significant number in the range between 15 and 30 stories high.   Many of these buildings have thin bearing concrete walls.  The building code in Chile follows closely ACI 318, with some key changes aimed at constructability.  Dr. Restrepo will present his observations of the performance of buildings in this large earthquake.
