This is followed by a period of intense volcanism, during which the new volcano erupts almost all (e.g. 98%) of its total magmatic volume.

It was also clearly a period of intense volcanism - with intrusive igneous rocks representing the ejected and intrusive molten matter from the interior of the Earth scattered about the region.

The Ring of Fire around the Pacific Ocean with its attendant intense volcanism and seismic activity poses a major threat for disastrous earthquakes, tsunamis and volcanic eruptions.

This area has also experienced intense volcanism, Arthur's Seat in Edinburgh being the remnant of a once much larger volcano active in the Carboniferous period some 300 million years ago.

The gases and water vapors and carbonaceous brews that formed the atmosphere and filled the seas were seen as having come from within Earth in an early period of intense volcanism.

The Pacific Plate is being subducted beneath the Okhotsk Plate along the trench, resulting in intense volcanism.

This area has also experienced intense volcanism, Arthur's Seat in Edinburgh being the remnant of a once much larger volcano.

On the permanent nightside, the surface is cool enough for the formation of the crust with pools of lava above the convective mantle with intense volcanism.

These so-called tidal forces heat its interior, powering its intense volcanism.

This is where rapid subduction of the Pacific Plate fuels the intense volcanism.
