One of the locations in the USA with a high hazard level for seismic activity is the state of California. This is because California lies on the San Andreas Fault, which is a major tectonic boundary where the Pacific Plate and the North American Plate meet. Consequently, California experiences numerous earthquakes, including some of the most significant seismic events in the country's history. Other areas with high seismic activity include Alaska, Washington, and Hawaii.
