Causes of Earthquakes

Earthquakes are primarily caused by the movement of tectonic plates beneath the Earth's surface. These massive slabs of the Earth's lithosphere are in constant motion, driven by forces such as mantle convection, gravitational pull, and the rotation of the Earth. When two tectonic plates interact, they can either move apart, slide past one another, or collide, resulting in the release of energy that manifests as an earthquake.

In the case of Los Angeles, the San Andreas Fault is a transform fault where the Pacific Plate and the North American Plate slide past each other horizontally. The friction between these plates causes stress to build up over time. When this stress exceeds the strength of the rocks along the fault line, it is released in the form of seismic waves, leading to an earthquake.

Aside from tectonic activity, earthquakes can also be triggered by other factors such as volcanic activity, human-induced activities like mining or reservoir-induced seismicity, and even meteorite impacts. However, the majority of significant earthquakes in Los Angeles are attributed to tectonic movements.
