The friction between the plates.
When the friction is resolved, an earthquake occurs.
two tectonic plates floating into each other.

California sits on the San Andreas Fault, a major tectonic boundary where two of Earth's tectonic plates interact. The movement of these plates causes stress to build up, which can lead to earthquakes. Due to the history of seismic activity in the region, scientists predict that a major earthquake in California is likely to occur in the near future.
usually an earthquake occurs because underneath the earths crust are tectonic plates and when they move occasionlly one will get caught but the outside is still moving and that causes an earthquake
The most recent major earthquake in Nevada happened in Wells, February 21 2008. Small earthquake happen all over the state every week because Nevada is on top of many fault lines.
The plates moved so this can occur the earthquake.
an earthquake
Small foreshocks that precede a major earthquake can occur
The earthquake in Tokyo occured because, Tokyo lies on three tectonic plates. When those plates come together, seperate, or slide past each other an earthquake happens. However, Tokyo is also a city in a major fault zone!
because of moving plates
Because there are tectonic plates there in the lithosphere.
example of these is the plates are moving in different ways and when it move the earthquake will occur
