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.
Most earthquakes are associated with the movement of tectonic plates, which make up the Earth's outer shell. The majority of earthquakes occur along plate boundaries, where these plates interact and sometimes collide or separate, creating stress and releasing energy in the form of an earthquake. Plate boundaries can be categorized as convergent, divergent, or transform boundaries, and earthquakes can occur along any of these types of boundaries.
California is associated with the most earthquakes in the United States due to its location along the San Andreas Fault, a major tectonic plate boundary. These earthquakes vary in size and frequency, with some causing significant damage and loss of life.
The lithosphere is most directly affected by earthquakes and volcanoes. Earthquakes occur when there is movement along faults in the lithosphere, while volcanoes are associated with the release of molten rock, or magma, through the lithosphere to the surface.

California is most commonly associated with earthquakes in the lower 48 US states. California sits along the San Andreas Fault, a major tectonic boundary that is known for producing large earthquakes. Washington also experiences earthquakes, but they are less frequent and severe compared to California.
Seismic waves are associated with earthquakes.

Most seismic activities are associated with areas of active tectonism. So earthquakes occurs principally in such areas.

Volcanoes can cause lava flows and large amounts of ash. They might be associated with earthquakes as well.
