It suddenly slips when the stress across it becomes too high, which produces a sudden series of shockwaves that radiate in all directions from the fault through the surrounding rock. The earthquake you feel happens when these shockwaves reach the surface.
An earthquake.
No an earthquake is caused because in that certain area where the earthquake was , there was a fault line.
The largest earthquake fault is San Andreas fault.
The closest major fault to Vallejo is the Hayward Fault, which runs along the western base of the East Bay Hills just east of the city. This fault is known for its potential to produce a significant earthquake in the future.
The 1920 Haiyuan earthquake, also known as the 1920 Gansu earthquake, occurred on the Haiyuan Fault. This fault is located in the Gansu province of China and is a major active fault in the region.
If the fault is responsible for the earthquake, there will be movement (displacement) along the fault.
painful fault
No. While the largest earthquakes the San Andreas Fault can produce are larger than the largest ones its "sister" faults can produce, not every earthquake it produces is that large. As an example, the San Andreas Fault caused the 2004 Park field earthquake, which was a magnitude 6.0. The Hayward Fault, which runs parallel to the San Andreas Fault, has generated earthquakes at least as strong as 6.8. The 1994 Northridge earthquake, a magnitude 6.7, was the result of a previously undiscovered thrust fault beneath Los Angeles.
If the fault is responsible for the earthquake, there will be movement (displacement) along the fault.
San Andreas fault.
The San Francisco earthquake was caused by a rift in the San Andreas fault.
It is a THRUST fault The San Andreas Fault
