San Andreas Fault. San Andreas Fault is a major continental transform boundary that is situated in the extreme western part of the continent of North America and forms the border between two principal tectonic plates: the North American Plate on the eastern side and the Pacific Plate on the western side.Since the Pacific Plate slides …by Gary S. Fuis, Daniel S. Scheirer, Victoria E. Langenheim, and Monica D. Kohler*. Abstract The widely held perception that the San Andreas fault (SAF) is vertical or steeply dipping in most places in southern California may not be correct. From studies of potential-field data, active-source imaging, and seismicity, the dip of the SAF is ...The New Madrid fault line is best known for some of the most violent earthquakes to ever hit the United States: a series of four in 1811 and 1812. The quakes were estimated at magnitude 7.5 to 8.0, so strong the Mississippi River reportedly flowed backward. Damage occurred as far away as Washington, D.C., and Charleston, S.C.A major fault line in Southern California capable of producing a magnitude 8 earthquake began to move for the first time in 500 years.

The Southern San Andreas fault (SSAF) poses one of the largest seismic risks in California. However, structural properties around Coachella Valley remain enigmatic. In 2019, we collected magnetotelluric soundings (MT) to help inform depth-dependent fault zone geometry, fluid content and porosity. This project was led by the Institute of Geophysics and Planetary Physics at the University of CaliforThe earthquakes of California are caused by the movement of huge blocks of the earth's crust- the Pacific and North American plates. The Pacific plate is moving northwest, scraping horizontally past North America at a rate of about 50 millimeters (2 inches) per year. About two-thirds of this movement occurs on the San Andreas fault and some ...Detailed Description. Map of faults in southern California.
