California is host to every type of volcano. The specific hazards to people and property depend on which volcano erupts, the style (effusive or explosive), the volume of lava, the location of the vent, the eruption duration, and local hydrologic (water) conditions. The severity of the hazard generally decreases with distance from the volcano vent.
The location of the San Andreas fault in the Shelter Cove area of northern California has been the subject of long-standing debate within the geological community. Although surface ruptures were reported near Shelter Cove in 1906, several subsequent workers questioned whether these ruptures represented true fault slip or shaking-related, gravity-driven deformation.
PROVIDENCE, R.I. [Brown University] — When the rigid plates that make up the Earth's lithosphere brush against one another, they often form visible boundaries, known as faults, on the planet's surface. Strike-slip faults, such as the San Andreas Fault in California or the Denali Fault in Alaska, are among the most well-known and capable of seriously powerful seismic activity.On October 21, 1868, a magnitude 6.8 earthquake struck the San Francisco Bay area.
