What is the plate tectonic setting of Mt Fuji?

Geological Setting

Fuji (or Fujisan) is a classical stratovolcano but its plate tectonic setting is quite complicated. It lies on the Eurasian tectonic plate with the Philippines Sea Plate subducting to the south and the Pacific Plate subducting to the north.

Which plate is the Eurasian Plate?

The Eurasian Plate is the third largest major plate. It consists of most of Europe Russia and parts of Asia. This plate is sandwiched between the North American and African Plate on the north and west sides. The west side shares a divergent plate boundary with the North American plate.

Where is Krakatoa tectonic plate?

Tectonic Setting

It is set in the Indonesian island arc system which was produced by northeastward subduction of the Indo-Australian Plate. Krakatau is directly above the subduction zone where the Eurasian Plate and Indo-Australian Plate meet creating a strato-volcano chain.

What tectonic plates made Krakatoa?

Krakatoa lies along the convergence of the Indian-Australian and Eurasian tectonic plates a zone of high volcanic and seismic activity. Sometime within the past million years the volcano built a cone-shaped mountain composed of flows of volcanic rock alternating with layers of cinder and ash.

What type of plate boundary is Iceland?

Iceland lies on the Mid Atlantic Ridge a divergent plate boundary where the North American Plate and the Eurasian Plate are moving away from each other.

Which tectonic plate interaction caused the island of Iceland?

The tectonic plates whose turbulent interactions formed Iceland are the Eurasian tectonic plate and the North American tectonic plate. Spanning the Mid-Atlantic Ridge Iceland emerged as a result of the divergent spreading boundary between these two plates and the activity of Iceland´s own hotspot or mantle plume.

What type of volcanism is Mount Fuji?

Mount Fuji is a composite cone or stratovolcano. Composite cones formed by violent eruptions have layers of rock ash and lava.Dec 6 2011

How Mount Fuji erupt?

Fuji. Due to the compression of the magma chamber basaltic lava rose from the bottom to the higher dacitic magma chamber at 8 km deep. The mixing of the two different types of magma caused a Plinian eruption to occur. Previous to the Hoei another earthquake named Genroku had struck Japan in 1703.

What tectonic plates are in Alaska?

The state’s location at the boundary between two major plates—the North American plate and Pacific plate—makes Alaska one of the most geologically active regions in the world. The Pacific plate moves northwest relative to the North American plate at a rate of about five to seven centimeters per year.

What type of plate boundary occurs between the Indo Australian and Eurasian plates?

This plate boundary is called the Sumatran Subduction Trench and it is where the oceanic Indian/Australian plate is slowly descending beneath (subducting under) the continental Eurasian plate at a rate of about 4.5 cm/year (2 inches/year).

What type of plate boundary is occurring between the Antarctic and Indo Australian plates?

The southerly side is a divergent boundary with the Antarctic Plate called the Southeast Indian Ridge (SEIR). The subducting boundary through Indonesia is not parallel to the biogeographical Wallace line that separates the indigenous fauna of Asia from that of Australasia.

Which two plates are involved in the formation of Mt Etna?

The volcano sits on the edge of a convergent plate boundary between the Eurasian Plate and the African Plate.

Did Mt Fuji erupt?

Mount Fuji is an active volcano that last erupted in 1707. On December 16 1707 scientists recorded the last confirmed eruption of Mount Fuji Japan’s highest point. … Fuji has erupted at various times starting around 100 000 years ago—and is still an active volcano today.

What tectonic plate is Mauna Loa located on?

Pacific tectonic plate
Like all Hawaiian volcanoes Mauna Loa was created as the Pacific tectonic plate moved over the Hawaii hotspot in the Earth’s underlying mantle.

How was the Eurasian Plate formed?

This immense mountain range began to form between 40 and 50 million years ago when two large landmasses India and Eurasia driven by plate movement collided. Because both these continental landmasses have about the same rock density one plate could not be subducted under the other.

What is Pacific plate and Eurasian Plate?

Eurasian Plate from the subducting Pacific Plate. (Some geologists argue that this portion of the Eurasian Plate is actually a fragment of the North American Plate called the Okhotsk microplate.) A part of the subduction zone measuring approximately 190 miles (300 km) long by 95 miles (150 km) wide lurched…

Which plate pushes the Philippine plate toward the Eurasian Plate?

The crust of the subducting plate is 5-20 km thick. The mantle composition of the subducting plate is progressively depleted from west to east.

Is Krakatoa a supervolcano?

In 1927 a fourth island Anak Krakatau or “Child of Krakatoa” emerged from the caldera formed in 1883. There has been new eruptive activity since the late 20th century with a large collapse causing a deadly tsunami in December 2018.

On December 29 1927 Anak Krakatoa emerged from the caldera formed in 1883 by the explosive volcanic eruption that destroyed the island of Krakatoa. … Due to its young age the island is one of several in the area which are of considerable interest to volcanologists and the subject of extensive study.

What type of volcano is Mount Krakatoa?

Mount Krakatoa is an example of a stratovolcano a tall conical volcano with multiple strata of solidified lava tephra as well as volcanic ash. These type of volcanoes typically have steep sides and usually erupt frequently & violently. Most of the popular eruptions have been made by stratovolcanoes.Sep 18 2009

What continent is Krakatoa in?

The volcanic island known as Krakatoa is located in the Sunda Strait between the islands of Java and Sumatra. At the time of its famous eruption in 1883 the region was part of the Dutch East Indies it’s now part of Indonesia.

When did Iceland form geologically?

about 60 million years ago
The formation of Iceland started about 60 million years ago when the mid-Atlantic ridge (the boundary between the North American tectonic plate and the Eurasian tectonic plate) started to give way and when mantle plumes appeared.Mar 5 2020

What caused the Hawaiian islands to form?

The Hawaiian Islands were literally created from lots of volcanoes—they’re a trail of volcanic eruptions. … In the case of the Hawaiian Islands the Pacific Plate is continually moving to the northwest over the Hawaiian hot spot. This movement caused the Hawaiian chain of islands to form.

Why is Iceland so geologically active?

Iceland is one of the most active volcanic regions on Earth where almost all types of volcanic and geothermal activity can be found. The volcanism on Iceland is attributed to the combination of the Iceland plume hotspot activity and the Mid-Atlantic Ridge activity. The Mid-Atlantic Ridge is visible on land.

How are volcanoes formed in Iceland?

Iceland formed by the coincidence of the spreading boundary of the North American and Eurasian plates and a hotspot or mantle plume – an upsurge of abnormally hot rock in the Earth´s mantle. As the plates moved apart excessive eruptions of lava constructed volcanoes and filled rift valleys.
