USGS-Led Study Reassesses Earthquake Hazard Potential for Central California’s Hosgri Fault
Regional map showing the main fault structures that are part of the Pacific–North American plate boundary along central California. The San Gregorio–Hosgri fault system is predominantly located near the coastline and highlighted in red. Inset map shows the focus region of this study where the Cross-Hosgri slope is located. A new study from United States Geological Survey (USGS) researchers and industry partners uses advanced sub-surface analyses and sediment dating to reassess the slip rate of the Hosgri fault off the central California coast. The research was led by Dr. Jared Kluesner, USGS Research Geophysicist at the Pacific Coastal and Marine
