Fault lines in northern california.

The Cascadia Subduction Zone is a 700-mile fault that runs from northern California up to British Columbia and is about 70-100 miles off the Pacific coast shoreline. There have been 43 earthquakes in the last 10,000 years within this fault. The last earthquake that occurred in this fault was on Jan. 26, 1700, with an estimated 9.0 magnitude.Owing to wiggles in the fault line, portions of the thin red lines can be more than 100 ft from the fault. By presenting the San Andreas Fault map as interactive web-based imagery, anyone can pinpoint the fault anywhere along its trace. And by using a thin red line, the underlying landscape features are minimally obscured.Department of Earth and Planetary Science, University of California, Berkeley, California, USA.

At over 800 miles ling, the San Andreas fault is the longest fault line in the United States and is responsible for the massive earthquake that decimated San Francisco on April 18, 1906. This fault extends from Southern California to off the Northern California coast just beyond San Francisco, getting its name primarily from its northern …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.
