Earthquakes are the most common natural disaster on the Pacific Coast.

The Pacific Coast is highly prone to earthquakes due to its location along the Pacific Ring of Fire, a region known for frequent seismic activity. The area is home to several major fault lines, including the San Andreas Fault, which is responsible for many of the earthquakes in California. These tectonic shifts occur as the Earth's plates move and interact, leading to earthquakes that can range from mild tremors to catastrophic events. While other natural disasters like flooding, hurricanes, and tornadoes can happen, earthquakes are the most common and often have significant impacts on the region.
