By presenting the San Andreas Fault map as interactive web-based imagery, anyone can pinpoint the fault anywhere along its trace. And by using a thin red line, the underlying landscape features are minimally obscured.

1. Introduction [2] The San Andreas Fault System (SAFS) is a complex network of predominantly strike-slip faults that forms a present day boundary between the North American and Pacific plates. The system extends from the Mendocino triple junction (MTJ) on the north to the Gulf of California on the south. SAFS is characterized by a relatively complex tectonics.The California Geological Survey periodically issues official maps of earthquake fault zones, in compliance with the Alquist-Priolo Earthquake Fault Zoning Act. Two examples of earthquake fault zone maps are shown in the figure below.The San Andreas Fault System is the dividing line between two tectonic plates. The Pacific Plate is moving in a northwesterly direction relative to the North American plate. The movement is horizontal, so while Los Angeles is moving …The Maacama fault is the northward continuation of the Hayward-Rodgers Creek fault system in northern California.
