When the magma reaches water at the ocean floor most spreading centers are in the ocean it cools and hardens and becomes new oceanic crust.
Does the san andreas fault make new ocean floor.
The fault divides into three segments each with different characteristics and a different degree of earthquake risk.
The san andreas runs deep near and under some of california s most populated areas the cities of desert hot springs san bernardino wrightwood palmdale gorman frazier park daly city point reyes station and bodega bay rest on the san andreas fault line.
San andreas fault line map.
As the plates continue to move apart more and more new basaltic crust is created.
The san andreas fault s nick name is saf.
The san andreas fault connects two divergent fault boundaries in the north and south.
The north coast section of the san andreas fault is north of san francisco.
For example in bodega bay the san andreas fault is actually located about 800 meters away from where it was thought to be.
Most transform faults are underwater but the san andreas fault is one of the few that is exposed on land.
It runs most of the length of california and into the ocean.
Transform faults have shallow earthquakes that are often quite damaging on land.
Prior to 1300 the intervals are shorter about 200 years.
The scale of the project started in 2007 by the california ocean.
