The Alpine Fault marks a transform boundary between the two plates, and further south the Indo-Australian Plate subducts under the Pacific Plate forming the Puysegur Trench. Powerful earthquakes shake a wide area on both sides of the boundary. The best paleoseismic evidence to date suggests the southern and central sections of the Alpine Fault, at the boundary separating the Australian and Pacific tectonic plates, typically rupture during very large full-section earthquakes of magnitude 7.7 or larger. By the end of this activity, students should be able to: At Hokuri Creek (Fig. This image shows the three main types of plate boundaries: divergent, convergent, and transform. The Earth’s lithosphere, which includes the crust and upper mantle, is made up of a series of pieces, or tectonic plates, that move slowly over time. The Alpine Fault is a geological fault that runs almost the entire length of New Zealand's South Island (c. 480 km) and forms the boundary between the Pacific Plate and the Indo-Australian Plate. A divergent boundary occurs when two tectonic plates move away from each other.

STUDENT ACTIVITY: New Zealand plate boundary models Activity idea In this activity, students make and/or observe two 3D moving models of the different tectonic plate boundaries under the North and South Islands representing the North Island subduction zone and the South Island Alpine Fault. Earthquakes along the fault, and the associated earth movements, have formed the Southern Alps. Nanoengineered Cement for Sealing Leaky Gas ... Critical Temperature for Tropical Tree Lifespan, Bioplastics from Sewage Sludge and Wastewater. Earthquakes are common along these faults. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench. Financial support for ScienceDaily comes from advertisements and referral programs, where indicated. Contact Us However, most of the motion on the fault is strike-slip (side to side), with the Tasman district and West Coast moving North and Canterbury and Otagomoving South. Transform Plate Boundaries. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed. 202 - Tectonic Plates • pg. EXPLORING THE PLANETS 3 The crust type and general of thickness of the crust. Transform plate boundaries occur where two lithospheric plate slide past each other horizontally along a single or a group of deep nearly vertical steep fault planes. When a tectonic boundary is oriented oblique relative to plate motion, a combination of strike-slip and dip-slip faulting will occur.

Disclaimer Answer to: Is the Alpine Fault convergent, divergent, or transform? 198- Pangea For the maps, you should know the layers of the Earth and be able to name all the major tectonic plates and where they are, as well as plate boundary … Two plates sliding past each other forms a transform plate boundary. The fracture zone that forms a transform plate boundary is known as a transform fault. More often, an array of strike-slip and dip-slip faults will operate together. The Alpine Fault is called a strike slip or transform fault. For more information, see the following related content on ScienceDaily: Content on this website is for information only. It’s the "on-land" boundary of the Pacific and Australian Plates. An Updated Model Provides Answers, Benefits of Renewable Energy Vary from Place to Place, Hazardous Micropollutants from Plastic Waste, Recovery of an Endangered Caribbean Coral. The mountains are rising at 7 millimetres a year, but erosion wears them down at a similar rate. Natural or human-made structures that cross a transform boundary are offset—split into pieces and carried in opposite directions. What are the different types of plate tectonic boundaries. The Alpine Fault cuts through New Zealand. The Alpine Fault, marked here by the yellow line, stretches nearly the entire length of Te Waipounamu, the South Island of Aotearoa New Zealand. The Alpine Fault, which runs for about 600km up the spine of the South Island, is one of the world’s major geological features.

It runs as a single structure for over 500 km. The Marlborough Fault System is a set of four large dextral strike-slip faults and other related structures in the northern part of South Island, New Zealand, which transfer displacement between the mainly transform plate boundary of the Alpine fault and the mainly destructive boundary of the Kermadec Trench, and together form the boundary between the Australian and Pacific Plates. St. Andreas Transform Fault Alpine Fault New Zealand The types of transform fault that are always the longest Oceanic Transform Fault Continental Transform Fault. Two tectonic plates (Oceanic and Continental) collide from compression stress and form a convergent plate boundary. Site Info, Office of Ocean Exploration and Research Have any problems using the site? •Chapter 7- Plate Tectonics, Ch.8 Earthquakes, Ch.9 Volcanoes pg. It is not intended to provide medical or other professional advice. T The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. The Alpine Fault is a geological fault, known as a right-lateral strike-slip fault, that runs almost the entire length of New Zealand's South Island. Website Satisfaction Survey Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. 6. 190 - Earth's Layers • pg. Natural or human-made structures that cross a transform boundary are offset—split into pieces and carried in opposite directions. The biggest faults mark the boundary between two plates. The type of plate boundary at the Alpine Fault is a transform boundary. Rocks that line the boundary are pulverized as the plates grind along, creating a linear fault valley or undersea canyon.
