The San Andreas Fault (western US), the North Anatolian Fault (Turkey) or the Dolores-Guayaquil Megafault in the northern Andes are some examples of huge strike-slip faults transecting continental crust. MORs are, of course, divergent plate boundaries where two. These may result in some of the most damaging earthquakes on continental crust. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary. Midocean ridge spreading centers (MOR on the map below) are offset by numerous transform faults. ![]() A fault is a crack in the earth's crust resulting from the movement of the two plates. When strike-slip movement halts due to increased friction at some location, stresses can build up that are released in sudden slips. The boundary where two separate plates meet is where all the action occurs and is called a fault. A single tectonic plate can have multiple types of plate boundaries with the other plates that surround it. A well-known transform plate boundary is the San Andreas Fault, which is responsible for many of California’s earthquakes. These structures are so-called strike-slip faults. A transform plate boundary occurs when two plates slide past each other, horizontally. Because rocks are cut and displaced by movement in opposite direction, rocks facing each other on two sides of the fault are typically of different type and age. Almost any road cut in the zone shows a myriad of small fractures, fault gouge (pulverized rock), and a few solid pieces of rock.The third type of plate boundary is the transform fault, where plates slide past one another without the production or destruction of crust. Many smaller faults branch from and join the San Andreas fault zone. Viewed in detail, the fault is a complex zone of crushed and broken rock from a few hundred feet to a mile wide. The entire San Andreas fault system is more than 800 miles long and extends to depths of at least 10 miles within the Earth. The San Andreas is the "master" fault of an intricate fault network that cuts through rocks of the California coastal region. It is a tectonic plate boundary, where two plates slide past each other horizontally, without forming or destroying the tectonic crust. Wallace, USGS.)The Pacific Plate (on the west) moves northwestward relative to the North American Plate (on the east), causing earthquakes along the fault. This earthquake, however, was but one of many that have resulted from episodic displacement along the fault throughout its life of about 15-20 million years.Īerial view of the San Andreas fault slicing through the Carrizo Plain in the Temblor Range east of the city of San Luis Obispo. What is a Transform Boundary Transform boundaries are created when tectonic plates slide past each other horizontally along strike-slip faults or transform faults. Several transform fault boundaries are involved.Ī sudden displacement along the fault on Approduced the great San Francisco earthquake and fire. The San Andreas fault is part of a complex structure of plate boundaries associated with the west coast of the United States. ![]() residents, the most famous example is the San Andreas fault in California. Neither production nor consumption of lithosphere occurs at these boundaries. Tectonic plates grind past each other at transform fault boundaries.
