Strike slip fault description11/30/2023 Contrary to popular belief, California will not suddenly "fall into the ocean." It will just continue moving at about 2 inches per year until, 15 million years from now, Los Angeles will be located right next to San Francisco. The southwestern portion of California is moving northwestward towards Alaska. While strike-slip faults occur across the world, the most famous is the San Andreas fault. Various studies of active and exhumed strike-slip faults have yielded high resolution descriptions of their internal structure and slip localization patterns. That means someone standing near the fault trace and looking across it would see the far side move to the right or to the left, respectively. Strike-slip faults are either right-lateral or left-lateral. The forces creating these faults are lateral or horizontal, carrying the sides past each other. In these faults, the fault plane is usually vertical so there is no hanging wall or footwall. That is, the slip occurs along the strike, not up or down the dip. The fault plane is essentially vertical, and the relative slip is lateral along the plane. Cross-sections through strike slip faults tend to be quite confusing, for this. Strike-slip (also called transcurrent, wrench, or lateral) faults are similarly caused by horizontal compression, but they release their energy by rock displacement in a horizontal direction almost parallel to the compressional force. The damage zones around strike-slip faults tend to contain a mixture of structures that we normally associate either with horizontal shortening (as in thrust belts) or with horizontal extension (as in rifts). Strike-slip faults have walls that move sideways, not up or down. Structures associated with strike-slip faults. jack0m/DigitalVision Vectors/Getty Images Strike-slip faults occur as plates scrape by each other.
