Is the Japan trench divergent or convergent?

Seismic activity along the Japan Trench occurs along the associated subduction zone at disruptive convergent plate boundaries between the Okhotsk and subducting Pacific plate. The continuing movement along these plate boundaries occur at a depth of about 8 000 metres (26 247 ft).

What plate boundary does a trench form at?


In particular ocean trenches are a feature of convergent plate boundaries where two or more tectonic plates meet. At many convergent plate boundaries dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction creating a trench.

Is there a trench off the coast of Japan?

Japan Trench deep submarine trench lying east of the Japanese islands in the floor of the western North Pacific Ocean. It is one of a series of depressions stretching south from the Kuril Trench and the Bonin Trench to the Mariana Trench.

What tectonic plates is Japan on?

Japan sits on or near the boundary of four tectonic plates: the Pacific North American Eurasian and Filipino plates.

What convergent boundary is Japan on?

The Pacific plate is moving westward and being subducted beneath the northern part of Japan which is on the Okhotsk Plate. The tectonic plates and their boundaries surrounding Japan. The epicenter of the earthquake is along the convergent margin where the Pacific Plate is being subducted beneath the Okhotsk Plate.

What type of plate boundary is Philippine Trench?

convergent zone
A convergent zone borders an estimate of 45% of the Philippine Trench today. Although there are vast areas of subduction zones some authors have considered this region to have low seismic activity though the USGS has recorded many earthquakes with magnitude ≥ 7.2 in the region as shown by the map to the side.

What type of plate boundary is at the Mariana Trench?

convergent boundary
In the case of a convergent boundary between two oceanic plates one is usually subducted under the other and in the process a trench is formed. “The Marianas Trench (paralleling the Mariana Islands) for example marks where the fast-moving Pacific Plate converges against the slower moving Philippine Plate.

What type of convergent plate boundary does the Mariana Trench represent?

The Mariana trench contains the deepest part of the world’s oceans and runs along an oceanic-oceanic convergent boundary. It is the result of the oceanic Pacific plate subducting beneath the oceanic Mariana plate.

Which type of boundary is made by Mariana Trench?

The boundary between the Mariana and the Pacific Plate to the east is a subduction zone with the Pacific Plate subducting beneath the Mariana.

What type of plate boundary is the Mount St Helens?

convergent plate boundary
Mt. St. Helens is a volcano in Washington near the Oregon border in the Cascade Range. The Cascade Volcanoes which stretch all from British Columbia through Northern California are stratovolcanoes that have formed inland from a convergent plate boundary where ocean crust is subducting below the continent.

Where is the Pacific plate?

The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km2 (40 million sq mi) it is the largest tectonic plate. The Pacific Plate contains an interior hot spot forming the Hawaiian Islands.

Are tectonic plates?

Tectonic plates are pieces of Earth’s crust and uppermost mantle together referred to as the lithosphere. The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium).

What type of plate boundary caused the Japan earthquake 2011?

In Northeast Japan (Tohoku) the Pacific plate is subducting northwestward beneath the Okhotsk plate causing the 2011 Tohoku-oki earthquake. Subduction is a process where one of Earth’s tectonic plates sinks under another.

How was Japan geologically?

The islands of Japan are primarily the result of several large ocean movements occurring over hundreds of millions of years from the mid-Silurian to the Pleistocene as a result of the subduction of the Philippine Sea Plate beneath the continental Amurian Plate and Okinawa Plate to the south and subduction of the …

What is the plate boundary?

Plate boundaries are the edges where two plates meet. Most geologic activities including volcanoes earthquakes and mountain building take place at plate boundaries. … Convergent plate boundaries: the two plates move towards each other. Transform plate boundaries: the two plates slip past each other.

What three plates converge on Japan?

Honshu Japan’s main island lies at the intersection between three tectonic plates: the Eurasian Philippine and North American.

What type of fault is Japan on?

The two best known faults in Japan are the Itoigawa-Shizuoka Tectonic Line (ISTL) which cuts across Honshu north to south just west of Tokyo and the Median Tectonic Line (MTL) which is an east-west trending strike-slip fault that parallels the Nankai Trough from the Kii Peninsula into the heart of Kyushu.

Is the Amurian plate oceanic or continental?

Among them Amuria (AM) is the northernmost continental domain extruded eastward in response to the India–Asia collision (Fig. 1). The Baikal Rift system and the Stanovoy range represent its western and northern boundaries with the Siberian Craton which pertains to the Eurasian Plate (EU).

Which type of convergent boundary created the Philippines and Japan?

The Philippine Sea Plate the Amurian Plate and the Okhotsk Plate meet near Mount Fuji in Japan. The thickened crust of the Izu–Bonin–Mariana arc colliding with Japan constitutes the Izu Collision Zone.
Philippine Sea Plate

Movement1 north-west
Speed1 48-84mm/year

Is the Philippine plate oceanic or continental?

Philippine Sea Plate is an oceanic plate surrounded by subduction zones. The plate is moving northwest at a rate of 6 – 8 cm/year towards the Eurasian Plate. Ranken and Cardwell (1984) showed that the rate of convergence increases southwards along the trench.

Is the Pacific Plate oceanic or continental?

An example of an oceanic plate is the Pacific Plate which extends from the East Pacific Rise to the deep-sea trenches bordering the western part of the Pacific basin. A continental plate is exemplified by the North American Plate which includes North America as well as the oceanic crust…

Is the Mariana Trench geologically active?

The active volcanoes of the Mariana Arc are mostly seamounts (underwater volcanoes) with summits that are only a few hundred meters (< 1 000 feet) below the ocean’s surface and only nine are tall enough to form islands. Many are spaced out along a chain with the largest volcano situated farthest east.

What is ocean-ocean convergent boundary?

At an ocean-ocean convergent boundary one of the plates (oceanic crust and lithospheric mantle) is pushed or subducted under the other (Figure 4.6. 1). … It mixes with the overlying mantle and the addition of water to the hot mantle lowers the crust’s melting point and leads to the formation of magma (flux melting).

Which type of zone is located at a deep ocean trench?

Deep-sea trenches generally lie seaward of and parallel to adjacent island arcs or mountain ranges of the continental margins. They are closely associated with and found in subduction zones—that is locations where a lithospheric plate bearing oceanic crust slides down into the upper mantle under the force of gravity.

Is Japan a oceanic oceanic convergent boundary?

Japan has been situated in the convergent plate boundary during long geohistorical ages. This means that the Japanese islands are built under the subduction tectonics. The oceanic plate consists of the oceanic crust and a part of the mantle beneath it.

What are the 3 convergent plate boundaries?

Convergent boundaries where two plates are moving toward each other are of three types depending on the type of crust present on either side of the boundary — oceanic or continental . The types are ocean-ocean ocean-continent and continent-continent.

Is the Nazca plate convergent or divergent?

The Nazca plate is an oceanic tectonic plate in the southeastern Pacific Ocean that shares both convergent and divergent boundaries corners multiple triple junctions contains three seamount chains overrides four hotspots and is responsible for the creation of the Andean orogeny (Figure 1).

Which plate boundary is formed between the Philippine plate and the Eurasian Plate?

subduction zone

The Nankai Trough subduction zone is a typical subduction system characterized by subduction of multiple geological units of the Philippine Sea Plate (the Kyushu-Palau Ridge the Shikoku Basin the Kinan Seamount Chain and the Izu-Bonin Arc) beneath the Eurasian Plate in the southwest of Japan.

What type of plate boundary is the Mid-Atlantic Ridge?

divergent boundaries
Perhaps the best known of the divergent boundaries is the Mid-Atlantic Ridge. This submerged mountain range which extends from the Arctic Ocean to beyond the southern tip of Africa is but one segment of the global mid-ocean ridge system that encircles the Earth.Sep 15 2014
