Detailed studies of piercing points show the San Andreas Fault has experienced over 225 km of movement in the last 20 million years, and this movement occurred at three different fault traces. Sesak naik (reverse fault atau thrust fault) Sesar jenis ini ditandai dengan salah satu blok batuan bergeser ke arah atas dan blok batuan lainnya bergeser ke arah bawah. What are the two types of faults differentiate There are three different types of faults: Normal, Reverse, and Transcurrent (Strike-Slip). The best type of piercing point includes unique patterns that are used to match the parts of a geological feature separated by fault movement. A strike-slip fault is a simple offset however, a transform fault is formed between two different plates, each moving away from the spreading center of a divergent plate boundary. Other types of faults-normal and reverse -tend to be more destructive, obscuring or destroying these features. Transform faults are unique because their horizontal motion keeps a geological feature relatively intact, preserving the record of what happened. Piercing points are very useful for recreating past fault movement, especially along transform boundaries. Reverse faults are indicative of shortening of the crust. A reverse fault is the opposite of a normal fault the hanging wall moves up relative to the footwall. The San Andreas Fault is one of the best examples of lateral plate motion. A special class of strike-slip faults is the transform faults which are a plate tectonics feature related to spreading centers such as mid-ocean ridges. When two tectonic plates slide past each other, the place where they meet is a transform or lateral fault. A strike-slip fault is a simple offset however, a transform fault is formed between two different plates, each moving away from the spreading center of a divergent plate boundary. When a geological feature is cut by a fault, it is called a piercing point. When the plates finally give and slip due to the increased pressure, energy is released as seismic waves, causing the ground to shake. Transform faults can be distinguished from the typical strike-slip faults because the sense of movement is in the opposite direction (see illustration). The fault can be seen about halfway down, trending left to right, as a change in the topography. This is caused by the San Andreas Fault cutting roughly perpendicular to the creek, and shifting the location of the creek over time. This stream offset is on the San Andreas fault in Carrizo Plain National Monument. Note as the creek flows from the northern mountainous part of the image, it takes a sharp right (as viewed from the flow of water), then a sharp left. Stream offsets are the counterpart to shutter ridges, a sign of lateral movement on strike-slip faults like the San Andreas fault. \): Wallace (dry) Creek on the Carrizo Plain, California.
