Performance of Buildings and Nonstructural Components in the 2014 South Napa Earthquake

On August 24, 2014, a magnitude-6.0 earthquake occurred in Napa, California. In response to this earthquake, the Special Projects task of the National Earthquake Technical Assistance Program (NETAP) was used to fund an investigation. At the time, this event had not yet been declared a federal disaster, and disaster funds were therefore not available. Because of limitations to this funding, some issues, such as performance of lifelines or building investigations in additional areas, could not be investigated. Past earthquakes in California have resulted in significant improvements to national and local building codes. For the 2014 South Napa earthquake, work was focused on documenting the observed performance of buildings and nonstructural components in order to lead into future improvements in future building codes, and to do so within six months.
