On August 24, 2014, a magnitude-6.0 earthquake, with an epicenter located 4 miles northwest of American Canyon, California, severely impacted the nearby city of Napa and the surrounding region, damaging commercial buildings, dwellings, and other building types. FEMA undertook a special project, carried out by the Applied Technology Council, to investigate the impacts of the earthquake. Maryann Phipps served as Project Co-Director and led a team of earthquake specialists to gather field data to better understand the performance of selected damaged and undamaged buildings. The earthquake provided an ideal opportunity to calibrate and evaluate existing earthquake hazard reduction methodologies and to expand existing knowledge and databases on the performance of buildings and nonstructural components. Results of the investigation were published in FEMA P-1024, Performance of Buildings and Nonstructural Components in the 2014 South Napa Earthquake.
