the Fault Activity Map of California is the method of fault compilation. Almost all of the Quaternary faults shown in the 2010 version of the Fault Activity Map have been digitally compiled from original-scale 1975 and 1994 maps, as well as more recent mapping when available. This compilation method insures that locations of these faults are moreJan 26, 2023 · A fault is a “weak point within a tectonic plate where pressure from the Earth’s surface can break through and cause shaking in an earthquake.”. Faults vary in length and seldom follow a straight line. The United States Geological Survey (USGS) explains that “ faults allow the blocks (of rock) to move relative to each other.

The fault's two tectonic plates will eventually draw closer to one another. As the plates shift and slide past one another, earthquakes will occur more frequently. Scientists predict that the fault line will extend more inland, through cities, and even farther from its original location as the plates continue to move. 2. Seismic RiskTitle: 2010 Fault Activity Map of California Author: Comments: The 2010 Fault Activity Map of California presents a much more detailed depiction of faults in California than previous versions.
