M6.9 Scenario Earthquake on the Rose Canyon Fault, Final Report – Is San Diego Prepared?

Rose Canyon Fault Zone investigations indicate a geologic history of many major earthquakes over the last 10,000 years. We cannot predict when the next one will occur, but we can be certain that it will. Is San Diego ready?

The final scenario report issued in March and this presentation outline the fault rupture, liquefaction, and ground shaking hazards expected to accompany a scenario earthquake and explore the potential impacts on buildings and infrastructure systems and the consequences for the San Diego community and economy.

How will the older buildings fare? Newer buildings? How will the critical lifeline utilities and transportation infrastructure systems fare? The airport and the Port facilities? What will be the impacts on government facilities and operations, on emergency services and response capacities? What will be the impacts on the tourism industry, waterfront activities, downtown business operations? On the border crossings and bi-national trade?

These questions are investigated and potential earthquake consequences are considered. Some key mitigation measures and strategies are suggested to better prepare San Diego for the inevitable future RCFZ earthquake and to help transform San Diego into a more seismically resilient city.

Scenario Mitigation Strategy #1:  Developing San Diego’s Vulnerable Building Inventory


The Scenario study identified San Diego’s older seismically vulnerable buildings as presenting the greatest risk to life, property, and emergency response following a major RCFZ earthquake.  As cities in California have worked towards providing more resilient and safer communities, new initiatives to pursue retrofit ordinances have become a theme throughout the state.  For each city, understanding the existing vulnerable building stock has been one of the critical steps towards developing a meaningful and effective program.


To support the scenario efforts, the SEAOSD EBC has inventoried a large portion of the downtown San Diego building stock and developed methods to effectively gather and record existing building data.  This inventory data will play a key role in assisting the City in making decisions regarding future seismic hazard mitigation ordinances and with city planning.  It is also the first step for future studies to be conducted which will expand our understanding of the vulnerability of the city’s building stock.
