Japan sits on a subduction zone, with the Pacific seafloor sinking downward beneath the island. That’s the cause of both Japan’s dangerous earthquakes and its volcanic peaks like Mt. Fuji.

Subduction zone volcanoes commonly exhibit a symmetric shape with steeper slopes near the vent and a broad gentle base. These stratovolcanoes produce a wide range of volcanic products including ...

Volcanoes form when the subducting oceanic plate becomes hot enough to melt materials and create magma that rises to the surface ... These mountains are entering the subduction zone and are melting.

Subduction zones are found around the world, mostly in coastal regions where an oceanic plate dives beneath a continental plate. The resulting geohazards include the largest earthquakes and tsunamis, ...

For subduction zone volcanoes, the average is usually 4%, rarely exceeding 8 wt%, which is considered superhydrous. Skip to main content. Your source for the latest research news.

Plate tectonics, responsible for deadly earthquakes and volcanoes around the globe, may also be a key factor in the success of life as we know it on the third planet, a new study suggests.

If we were to draw a schematic cartoon diagram of a subduction zone, it would include a diving oceanic plate, represented by a uniform slab. As the plate dove deeper, water driven off by the ...

Another way volcanoes can form is what's known as hotspot volcanism. In this situation, a zone of magmatic activity —or a hotspot—in the middle of a tectonic plate can push up through the ...

Inland of each subduction zone lies a chain of spouting volcanoes called a volcanic arc, such as Oregon's Cascades, Alaska's Aleutian Islands and Indonesia's 130 active volcanoes.
