Earthquakes and other frequent tectonic activities is a characteristic of this region. The Aegean-Anatolian micro plate is forced to move westwards due to the collision between the African and Eurasian plates. This fault zone is a part of western Turkey, in the Marmara sea. The intensity and frequency of tectonic activity differs for every segment.Ģ004: Parkfield earthquake ➤ North Anatolian Fault It has been divided into three segments of northern, central, and southern. The fault zone is around 1,300 km long and runs through the state of California. The fault joins the East Pacific Rise and the South Gorda – Juan de Fuca plate. The Pacific plate is moving alongside the North American plate for millions of years. It is a transform boundary formed on the west coast of North America in California. They are also known as conservative boundaries, as no new crust (lithosphere) is created or destroyed. There are, however, a few transform boundaries that occur on continents. They generally offset the spreading ridges on the ocean floor by zigzag plate margins. They also connect two trenches at subduction zones (where one tectonic plate is going underneath another), or a ridge with a trench. They generally connect the segments of the diverging mid-oceanic ridges. Transform faults end at the junction of another plate boundary or another fault. One segment of the east moving part of the ridge slides alongside another segment of the westward moving part of the ridge. Transform faults occur on the sides of these segments, which during divergence, move past each other. Now, consider the crust on both the sides of the ridge to be divided into bands of horizontal parallel segments. The divergent boundary is not a straight line however, it is zigzag and crooked. (This occurs most commonly at a mid-oceanic ridge like the Mid-Atlantic Ridge in the Atlantic Ocean). Let us imagine that there are two divergent tectonic plates such that one plate is moving away from the other. It is a tectonic plate boundary, where two plates slide past each other horizontally, without forming or destroying the tectonic crust. spreading centers), or occasionally, convergent plate boundaries (e.g. He proposed that such large faults connect two divergent plate boundaries (e.g. The Canadian geophysicist John Tuzo Wilson is the father of the concept of transform boundaries. However, some regions like the transform boundaries, which although tectonically active, are the silent revolutionaries, as they do not alter the shape of the Earth phenomenally. Some such activities are responsible for the formation or destruction of geological features on land. The interaction between landmasses and water bodies is guided by the activities in the Earth’s interior.
Plate tectonics have given the Earth’s surface its present shape. The Indo-Australian, Pacific, and Antarctic plates meet at the Macquarie Triple Junction south of New Zealand. It is the region where three tectonic plates collide with each other. This ScienceStruck article provides information regarding this boundary is, along with its examples. A type of plate tectonic boundary, other than the convergent and divergent boundaries is the transform boundary.
