Like the 1971 Sylmar Earthquake and earlier seismic events, the 1994 Northridge Earthquake was another reminder that the health care system had critical fragilities and shortcomings in its ability to provide reliable critical services in a time of emergency. Just months after the Northridge earthquake, the State of California enacted what is known as Senate Bill 1953 (SB 1953) which was an amendment to the Alfred E. Alquist Hospital Seismic Safety Act of 1983 (commonly known as the Alquist Act). The Alquist Act established a seismic safety building standards program under the Department of Health Care Access and Information’s (HCAI) jurisdiction for hospitals built on or after March 7, 1973. The Act was initiated because of the loss of life incurred due to the collapse of hospitals during the Sylmar earthquake of 1971. The Act emphasizes that essential facilities, such as hospitals, should remain operational after an earthquake. Hospitals built in accordance with the standards of the Act resisted the January 1994 Northridge earthquake with minimal structural damage, while several facilities built prior to the Act experienced major structural damage and had to be evacuated. However, certain nonstructural components of the hospitals did incur damage, even facilities built in accordance with the structural provisions of the Act. The provisions and subsequent regulation language of SB 1953 amended the Act to address the issues of survivability of both nonstructural and structural components of hospital buildings after a seismic event. Therefore, the ultimate public safety benefit of the Act is to have general acute care hospital buildings that not only are capable of remaining intact after a seismic event, but also capable of continued operation and provision of acute care medical services after a seismic event. SB 1953’s purpose is to provide resiliency to the healthcare system to be able to provide the needed critical care services when disasters like earthquakes occur. This webinar will provide an overview of the SB 1953 program and present the progress of the program towards its ultimate goal of providing resilience in healthcare in California and be a model for other communities that face similar hazards.

Social science research on businesses affected by the Northridge earthquake was ground-breaking for understanding business interruption and losses, with an emphasis on how factors such as business characteristics and building and infrastructure performance affect outcomes for firms and organizations. In addition to providing an understanding of how businesses fare in the aftermath of disasters, organizational-level findings provided data inputs for the development of regional impact modeling. This webinar will provide an overview of the methods and findings from Northridge earthquake research and how studies of subsequent earthquakes, for example the 2014 S. Napa and the 2023 Kahramanmaras earthquakes, were influenced by but also expanded on the approach. The catalyst of the Northridge study is also evident in the framing of economic analyses for the HayWired earthquake scenario, including aspects of business characteristics, damage patterns, and macroeconomic impacts.

Episode 1 brought together experts from geophysics, geotechnical engineering, lifeline infrastructure systems, and structural engineering to provide an integrated view of the effects of the impactful Northridge Earthquake. While this dramatic event brought destruction to the heart of Los Angeles, it also improved understanding and engineering practice as we prepare for future earthquakes.
