U.S. Geological Survey - Western Region Office

The U.S. Geological Survey (USGS) operates within the broader Bay Area primarily through its prominent Pacific Coastal and Marine Science Center to study natural hazards and map coastal ecosystems. Based out of its strategic facility in Santa Cruz, the federal scientific agency conducts extensive offshore data collection, seafloor mapping, and seismic activity tracking across northern California's complex fault lines and waterways. Their targeted regional research provides the critical, data-driven science and public safety warnings required to evaluate earthquake risks, monitor coastal erosion, and build long-term climate resilience along vital shorelines.
