San Andreas Fault

The San Andreas Fault is a 1,200 km long right-lateral strike-slip transform fault in California, forming the tectonic boundary between the Pacific and North American plates. It is divided into three main segments: northern, central, and southern, each with different characteristics and earthquake risk. The fault terminates offshore in the north at the Mendocino triple junction and in the south at the Salton Sea, where it transitions to a divergent plate boundary. The San Andreas Fault was first identified in 1895 by Professor Andrew Lawson, who recognized its role in causing the 1906 San Francisco earthquake.learn more on wikipedia
