what type of plate boundary causes the largest earthquakes?
15761
A convergent plate boundary , also known as a destructive plate boundary , usually involves an oceanic plate and a continental plate. The plates move towards one another and this movement can cause earthquakes. As the plates collide, the oceanic plate is forced beneath the continental plate.

Yes, a divergent plate boundary can create earthquakes. There are two primary types of divergent boundaries; spreading ridges in the oceans, and rift valleys on land. They create earthquakes in different ways. To get an earthquake, surfaces need to move over each other.

Subduction zones occur all around the edge of the Pacific Ocean, offshore of Washington, Canada, Alaska, Russia, Japan and Indonesia. Called the "Ring of Fire," these subduction zones are responsible for the world's biggest earthquakes, the most terrible tsunamis and some of the worst volcanic eruptions.

Earthquakes at divergent plate boundaries occur as new crust is created and other crust is pushed apart. This causes the crust to crack and form faults where earthquakes occur. Most earthquakes at divergent plate boundaries occur at mid-ocean ridges where two pieces of oceanic crust are moving away from each other.

Earthquakes occur at plate boundaries when built up pressures in rocks suddenly release causing the plates to move along a fault line. A) Circum-Pacific belt-Encircles the outer rim of the Pacific Ocean. This area is the most active for earthquakes and volcanoes in the world.

Convergent boundaries form strong earthquakes, as well as volcanic mountains or islands, when the sinking oceanic plate melts. The third type is transform boundaries, or boundaries where plates slide past each other, forming strong earthquakes.

Transform plate boundaries, have shallow, but very powerful earthquakes. At convergent plate boundaries, where two continental plates collide earthquakes are deep and also very powerful.

Tectonic Plate Boundaries The Pacific Plate (on the west) slides horizontally northwestward relative to the North American Plate (on the east), causing earthquakes along the San Andreas and associated faults. The San Andreas fault is a transform plate boundary, accomodating horizontal relative motions.

There are places on the earth where the movement of the plate causes them to collide. These collisions cause convergent boundaries. The collisions of large masses of the crust result in mountains ( such as the Himilayans ) , earthquakes ( such as the San Andreas fault) .

By far the most active deep focus faulting zone in the world is that caused by the Pacific Plate subducting under the Australian Plate, Tonga Plate, and Kermadec Plate. Earthquakes have been recorded at depths of over 735 kilometres (457 mi), the deepest in the planet.

Students explore geologic events at converging plate boundaries. BACKGROUND: Most earthquakes and volcanoes occur because of the movement of the plates, especially as plates interact at their edges or boundaries. At diverging plate boundaries, earthquakes occur as the plates pull away from each other.

Earthquakes happen along the edges of tectonic plates and fault lines and there are three large zones on our planet which are most susceptible to earthquakes. These are the Circum-Pacific Seismic Belt, the Alpide Belt, and the Mid-Atlantic Ridge.

Earthquakes can occur at the three different plate boundaries, but some plate boundaries produce more earthquakes. This is due to the amount of friction exerted on the rocks. Transform plate boundaries occur where one plate slides past another. Only strike-slip faults are associated with transform boundaries.

Transform boundaries typically produce large, shallow-focus earthquakes. Although earthquakes do occur in the central regions of plates, these regions do not usually have large earthquakes.

About 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on.

Subduction zone earthquakes follow the descent of the Pacific plate down to 200 km or more. Alaska's largest earthquakes, exceeding magnitude 8 and even 9, occur primarily in the shallow part of the subduction zone, where the crust of the Pacific Plate sticks and slips past the overlying crust.

A destructive plate boundary is sometimes called a convergent or tensional plate margin. This occurs when oceanic and continental plates move together. The oceanic plate is forced under the lighter continental plate. Friction causes melting of the oceanic plate and may trigger earthquakes.
