San Andreas Fault
The San Andreas Fault is a major geological fault located in California, USA. It is a transform fault, which means it is a boundary where two tectonic plates slide past each other horizontally. The fault is part of the boundary between the Pacific Plate and the North American Plate.

The San Andreas Fault extends for about 1,200 kilometers (750 miles) through California, from the Salton Sea in the south to Cape Mendocino in the north. It is one of the most studied and well-known faults in the world, because it is located in a heavily populated area and has the potential to cause major earthquakes.
The fault has produced several large earthquakes in the past, including the 1906 San Francisco earthquake, which had an estimated magnitude of 7.9 and caused widespread damage and loss of life. The fault is expected to produce more large earthquakes in the future, as the two plates continue to move past each other.
There are ongoing efforts to monitor and study the San Andreas Fault in order to better understand its behavior and the potential hazards it poses to the region.
The San Andreas Fault is known for producing some of the largest and most devastating earthquakes in California's history. The following are some of the notable earthquakes that have occurred along the San Andreas Fault:
1857 Fort Tejon earthquake: This earthquake had an estimated magnitude of 7.9 and ruptured about 225 miles of the southern part of the San Andreas Fault. It caused significant damage and a few fatalities.
1906 San Francisco earthquake:
This is the most famous earthquake associated with the San Andreas Fault, with an estimated magnitude of 7.9. It caused widespread damage and fires in San Francisco, resulting in the loss of thousands of lives and property.
1957 Daly City earthquake: This earthquake had a magnitude of 5.3 and caused damage to several buildings in the city of Daly City.
1989 Loma Prieta earthquake: This earthquake had a magnitude of 6.9 and caused significant damage and loss of life in the San Francisco Bay Area.
It was particularly notable because it occurred during a World Series baseball game and was televised live.
2019 Ridgecrest earthquake: This earthquake, with a magnitude of 7.1, occurred in a remote part of California but was felt over a wide area, including Los Angeles. It caused damage to buildings and infrastructure in the area.
The San Andreas Fault remains a significant earthquake hazard, and scientists continue to monitor and study it in order to better understand its behavior and potential impact on the region.
