New research from San Jose State University reveals critical data about California’s most famous plate boundary. Following recent seismic activity along the Hayward Fault, geologists led by Professor Kim Blisniuk examined a 10,000-year window at Sanborn County Park to uncover how fast strain is building along the Santa Cruz Mountains section.
In this video, we break down:
The New Science: How cosmogenic radionuclide dating revealed a constant, faster slip rate (~20mm/year) matching the North Coast section.
Geophysics & Tectonics: Why higher slip rates between the Pacific and North American plates mean faster elastic strain accumulation—and what that means for earthquake frequency.
Historical Impact: Looking back at major events like the 1906 San Francisco (M7.9) and 1989 Loma Prieta (M6.9) earthquakes.
Preparedness: Key tips on building an emergency earthquake kit so you're ready when the big one strikes.
