The first notable earthquake was April 18, 1906, which was the cause of the great San Francisco earthquake and fire. In 1989 there was an earthquake in San Francisco Bay Area and was a 6.9 and killed 63 people. This quake is known as the "Quake of '89" or the "World Series Earthquake".
The result is commonly known as an earthquake.
Aftershocks are smaller earthquakes that occur after a larger earthquake in the same area. They are a result of the earths crust near the fault rupture readjusting as a result of the main earthquake (also known as the "main shock").
"Yes. Deductibles on insurance are usually affordable, especially if you live close to a known fault line."
California has more earthquakes then Florida, because California sits along the San Andreas Fault line. ( )-improvement, actually California sits on a series of many fault lines, the San Andreas only being one of them. San Andreas runs most of the length of the coast of California and is well known because it has a hard "kink" near LA which causes more violent earthquakes when it shifts, and can actually be seen in the topography of some areas of California from overhead.These fault lines are also a part of the "ring of fire" which causes the majority of the earthquakes and volcanoes along the West Coast of N America, Japan, and many of the Island chains of the Pacific.
The San Andreas fault!The San Andreas Fault
The largest geographical fault in California is the San Andres fault. This large fault is responsible for the largest quakes to hit the state. The San Jacinto, Elsinore, and Imperial are smaller parallel faults to the San Andres.
San Andreas fault
The best known is the San Andreas Fault.
San Andreas fault
The name of the transform boundary that separates the Pacific Plate and the North American Plate is known as the San Andreas Fault. It is the site of many of the earthquakes that plague Southern California.
The San Andreas Fault is a transform fault (also known as a strike-flip fault). It is where two plates are sliding past each other in opposite directions.
The first notable earthquake was April 18, 1906, which was the cause of the great San Francisco earthquake and fire. In 1989 there was an earthquake in San Francisco Bay Area and was a 6.9 and killed 63 people. This quake is known as the "Quake of '89" or the "World Series Earthquake".
If there is little or no earthquake activity on a fault, or a section of a fault then it may be: Inactive (no longer moving) Locked (If it is known to be building up strain for a future large earthquake, i.e. San Andreas) or It may be releasing nearly all it's stress by creeping, rather than in large quakes.
San Andreas Fault
The focus (more correctly termed the hypocenter) of an earthquake is the point in the earth where the earthquake rupture or fault movement actually occurred. The point on the surface directly above the hypocenter is known as the epicenter.
A well-known transform boundary in California is the San Andreas fault.
