Earthquakes occur along the San Andreas Fault because of the tectonic plates. When the plates slip or shift, an earthquake happens.
Earthquakes almost always occur along fault lines because fault lines are formed by 2 tectonic plate borders colliding and grinding on each other, and when pressure builds up... ***SNAP*** a crack, or fault, is created. When the tectonic plates shift back together, or apart, a Earthquake occurs, since the fault is expanding and collapsing.
there is a fault line in san andreas
and due to plate tectonics, the earths plates shift and hit each other causing earthquakes
when two plates are slide past one another an example is the san Andreas fault California which is the boundary between the north America and pacific plates
Dynamic Metamorphism >.<
It result from the moving of rock deep under the ground. This movement is caused by the rubbing of one plate into another. The plates have jagged edges, and so when they rub against each other, they get stuck. Since plates constantly move, the plates that are stuck create great tension, and when they are finally free, a huge amount of energy is released. Shock waves move from focus in all directions, and it causes the earth to vibrate.
Faults are breaks in the crust where the crust has moved. The types of dip-slip faults are normal and reverse faults. In both of these, the movement is along the slope of the fault. Sudden movements along these faults can produce fault scarps. Layers of rock being misaligned is evidence of fault movement. Fault creep is caused by slow movement along the fault.In a normal fault, the plates are moving away from each other. This is due to tension. When the fault moves, the footwall rises relative to the hanging wall. Normal faults occur at divergent boundaries, such as ocean ridges. Normal faults can produce fault-block mountains.In a reverse fault, the plates are moving towards each other. This is due to compression. Here, the footwall falls relative to the hanging wall. A thrust fault is a special type of reverse fault, where the angle is shallow. Reverse faults occur at convergent boundaries, like subduction zones.A strike-slip fault is where the two plates move horizontally past each other. The force between them is called shearing. This type of fault is often called a transform fault, because they occur at transform boundaries.
Haiti is an example of a transform boundary, because the left side of Haiti (where Port Au Prince is located) is the boundary of a tectonic plate that is sliding past another tectonic plate going in the other direction (Transform boundary). Because of this, a lot of tension builds up between the two plates, until an earthquake occurs when they slide past each other. (Keep in mind that tectonic plates move very little, and it took Pangea 250 million years to become what we see the world as now).Think, today (this is recent news as of January 20, 2010) when you turn on the news you hear of the devastating effects of a 7.0 earthquake in Haiti. This was because of the tectonic plates going in opposite directions against each other, i.e. the transform boundary!The most famous example is the San Andreas Fault in California.Transform boundaries -- where crust is neither produced nor .... one of the most visible and spectacular consequences of plate tectonics. ... However, a few occur on land, for example the San Andreas fault zone in California.
Earthquakes occur along a fault. Near the San Andreas fault lots of earthquakes occur.
Earthquakes occur along the San Andreas Fault because of the tectonic plates. When the plates slip or shift, an earthquake happens.
Movement along the fault causes earthquakes; several thousand occur annually, although only a few are of moderate or higher magnitude.
AnswerAccording to the USGS, the plates along the San Andrea fault move about 1.7in per year.
it is because of the fault line that is called San Andreas fault
Rocks can form rift valleys and mountains.
Most earthquakes occur on active fault lines such as the San Andreas fault in California. Most fault lines are under water but some come above water, such as the San Andreas fault in San Francisco and the fault line in Iceland. The San Andreas fault caused the great fire in San Francisco.
The Ring of Fire and the San Andreas Fault
Along fault lines. Major fault lines occur where the tectonic plates meet each other. The plates will either rub against each other or one will force the other underneath it, which commonly causes earthquakes.
Anywhere along fault lines.
