Nevada is one of the most seismically active states in the country, ranking third after California and Alaska. To blame are the state's many faults, found at the base of almost every mountain range.

USGS map showing faults that span the Pacific–North America plate boundary. The Hayward Fault Zone is a right-lateral strike-slip geologic fault zone capable of generating destructive earthquakes. The fault was first named in the Lawson Report of the 1906 San Francisco Earthquake in recognition of its involvement in the earthquake of 1868. [1]The Hayward Fault is thought capable of generating a magnitude 7.5 quake. However, many scientists believe that the Hayward Fault is connected to the Calaveras Fault to the south, the Rodgers Creek Fault to the north and to the Maacama Fault still farther north. If that is the case, the longer fault system could produce larger temblors.

The San Andreas Fault—made infamous by the 1906 San Francisco earthquake—is a strike-slip fault. This means two fault blocks are moving past each other horizontally.

These volcanoes rest above the active Cascadia subduction zone, …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.Most of central and northern California rests on a crustal block ( terrane) that is being torn from the North American continent by the passing Pacific plate of oceanic crust. Southern California lies at the southern end of this block, where the Southern California faults create a complex and even chaotic landscape of seismic activity.More than 22 million people live along Southern California’s coast, and many more migrate there every year. Faults and earthquake threats in this region have been heavily studied on land. USGS aims to boost our knowledge about faults on the seafloor, so they can be included in hazard assessments.
