The heightened earthquake risk poses significant threats to the densely populated communities in the East Bay, including Fremont, Hayward, Oakland, and Santa Rosa. A worst-case scenario could involve a linked rupture between the Hayward and Rogers Creek faults, potentially generating a 7.4 magnitude earthquake. Such an event could lead to widespread social and economic disruption, including property damage, infrastructure collapse, and long-term financial consequences for residents and businesses. Dr. Jones also highlighted the often-overlooked economic risks, such as potential bankruptcies, that could follow a major seismic event.
