On the anniversary of the devastating Loma Prieta quake, we hear from the USGS about the threat posed by the Hayward Fault, get an assessment from the Building Inspection Department of how the city's soft-story buildings would fare with major shaking, learn how neighbors can mobilize in a disaster with NERT, and bring dispatches from the unveiling of a statewide earthquake early warning system.
