Public Response to a Catastrophic Southern California Earthquake: A Sociological Perspective

This paper describes a hypothetical scenario of public response to a large regional earthquake on the southern section of the San Andreas Fault. Conclusive social and behavioral science research over decades has established that the behavior of individuals in disaster is, on the whole, controlled, rational, and adaptive, despite popular misperceptions that people who experience a disaster are dependent upon and problematic for organized response agencies. We applied this knowledge to portray the response of people impacted by the earthquake focusing on actions they will take during and immediately following the cessation of the shaking including: immediate response, search and rescue, gaining situational awareness through information seeking, making decisions about evacuation and interacting with organized responders. Our most general conclusion is that the actions of ordinary people in this earthquake scenario comprised the bulk of the initial response effort, particularly in those areas isolated for lengthy periods of time following the earthquake

Real-time earthquake hazard assessment in California; the early post-earthquake damage assessment tool and the Caltech-USGS broadcast of earthquakes

A real-time earthquake monitoring system which provides source parameters to user groups through a commercial paging service is now in place in California. A GIS-based system to predict and display near real-time damage and casualty estimates is currently being developed by EQE International under contract with the State of California. These new technologies offer immediate tangible benefits to state and local governments, utilities, lifelines and corporations with facilities or operations at risk. This paper will outline the development of these new technologies, identify the contributions they will make to emergency management and explore some directions these innovative systems may take in the future
