![]() The common examples of convergent boundaries are the subduction zones that are formed when the heavier plate slides beneath the lighter plate, creating a deep trench.Convergent Boundaries are also called destructive boundaries. When two tectonic plates collide, a convergent plate boundary is formed.They remold or revamp the earth’s surface leaving a trail of geologic features.Three types of tectonic borders are formed by the movement of tectonic plates: Convergent Boundaries The transform boundaries truly live up to their name as transforming beasts. ![]() More than 10 earthquakes have been associated with it in the 20th century with the latest being in 1956 when a 7.1 magnitude earthquake struck near Mandalay killing 38 people. The lock it produces tends to remain for several years before releasing the accumulated stress in huge earthquakes. Its average movement per year is about 16 to 20 millimeters. It runs right through the Asian nation Myanmar, with several urban areas on its path such as Pyi Taw which is Myanmar’s capital. This 1200 km fault lies between the Sunda Plate and the Indian plate. It has been the scene of powerful earthquakes, five of which occurred in only the last 100 years, the latest being the 2013 magnitude 7.5 one. This fault extends for more than 900 km marking the boundary of the North American plates and the Pacific Plates. You can enjoy a view of its full length which can be seen from the air and space. ![]() It is Afghanistan’s largest fault, running through Chaman, a town in southern Afghanistan. It consists of numerous connected faults that mark the boundary of the Indo-Australian plate and the Eurasian plate. This 850 km fault is located in Afghanistan and Pakistan. Geologists believe that in the past almost 900 years, rupturing of the fault has occurred four times 3. The alpine fault runs 600 km through the South Island and is clearly visible on land when viewed from space.Īt 30 m per 1000 years, its movement is considered to be quite fast. However, they also undergo a similar rate of erosion leaving their level relatively unchanged. These are mountain ranges with an interesting feature: they rise by 7 millimeters each year. This lateral movement has created the Southern Alps. It is characterized by the horizontal sliding motion between the Australian plate in the Pacific plate. That’s because one city is located in one plate and the other in the other plate that are moving relative to each other. The fault is responsible for some deadly major earthquakes such as the San Francisco earthquake of 1906 and the Loma Prieto earthquake of 1989.Īlthough San Francisco is currently located 340 km north of Los Angeles, their positions will be reversed given 16 million years! The fault links the Cascadia subduction zone with a divergent boundary running through the Gulf of California. The cause of all this sensation is the San Andreas Fault which is the best-known transform boundary. If you are a resident of California, you may be very accustomed to frequent predictions about imminent earthquakes-some of which pass. This is unlike divergent boundaries where new oceanic crust is generated and convergent boundaries where old oceanic crust undergoes destruction. One key aspect of transform plate that distinguishes it from divergent boundaries and convergent boundaries is that crust is not created or destroyed. In fact, the huge Pacific Plate features all boundary types i.e., convergent, divergent, and transform boundaries. Transform boundaries don’t always exist alone. ![]() Transform boundaries are also termed strike-slip boundaries, transform fault boundaries, conservative plate boundaries, or transform plate margins. This is the cause of massive earthquakes. Such locks can hold tectonic forces that accumulate over time.Įventually, the intensifying force overcomes the lock, causing a slip and a huge jump, usually extending to 8 meters. This is because of the interlocking that takes place between the two sides. The movements of the plates as they slide past each other are not smooth. Transform plate boundaries typically form on seafloors where they act as connections between mid-ocean spreading ridges. The plates’ grinding action against each other can produce phenomenal effects such as shallow earthquakes, widespread deformation of the crust, and displacement of rock. A transform boundary (also called a transform fault), is a fractured area or Faultline on the earth’s surface where two tectonic plates slide horizontally past each other.
