The Culprit in Mexico City-Amplification of Motion

Abstract Mexico City has repeatedly suffered from the the long-distance effects of the earthquakes that originate as far away as the subduction trenches near the Mexican Pacific Coast. The Michoacan, Mexico earthquake of 19 September 1985 was no exception and caused extensive damage to property and numerous loss of lives. The unique subsurface condition resulting […]

Engineering Aspects of the September 19, 1985 Mexico Earthquake

 Abstract Following the September 19, 1985 Mexico earthquake, a team consisting of four engineers and one seismologist from the Naitonal Bureau of Standards (NBS)and the United States Geological Survey (USGS) was dispateched to Mexico City to provide technical advice to the U.S. rescue effort and to assess structural damage. This report is primarily based on […]

32 Years After Michoacán: Preliminary Reconnaissance Observations in the Aftermath of the September 19, 2017 Puebla-Morelos Earthquake

Abstract In the wake of the devastating Central Mexico earthquake on Tuesday, September 19th, a team of SOM engineers traveled to Mexico City to contribute to post-disaster recovery efforts. Shortly after the 7.1 magnitude earthquake struck, three structural engineers based in SOM’s San Francisco and Los Angeles offices—Abel Diaz (M.EERI, 2011), Patrick Murren, and Samantha […]
