Project Title: September 19, 2017 Puebla-Morelos, Mexico Earthquake: Seismological and Structural Observations by the ATC Reconnaissance Team
Funding Source: ATC Endowment Fund
Purpose: Following the magnitude-7.1 Puebla-Morelos, Mexico earthquake on September 19th of 2017, the Applied Technology Council (ATC) deployed to the field an interdisciplinary team of seismologists, structural and geotechnical engineers, tasked with performing reconnaissance and collecting building design and strong ground motion information. The team arrived in Mexico City on October 10th, 2017 and worked with local agencies and academic institutions for the duration of one week. The ATC-141 report documents the findings of the field team, including observation of earthquake effects for 70 buildings, microtremors recorded using monitoring instruments at 7 buildings, and a compilation of processed ground motion recordings from UNAM (National Autonomous University of Mexico) and CIRES (Center of Instrumentation and Seismic Records). This report also serves as a reference to two papers approved for publication in Earthquake Engineering Research Institute (EERI) Spectra Journal.
Acknowledgements: The field team was primarily supported by the ATC Endowment fund, which was established in 1989 with a purpose to support projects of critical interest to structural engineering design practice, research, and education. Additional support was provided for instrumentation by the National Science Foundation (NSF) Grant #1810899.
