volcanoes are located within tectonic plates. They are fueled by localized sources of high heat energy known as thermal plumes. These plumes of molten rock, called magma, rise from the lower asthenosphere. They are much hotter than the typical lithosphere rock. This magma melts the surrounding ar...
Mount Hood, highest peak (11,239 feet [3,425 metres]) in Oregon, U.S., and the fourth highest peak in the Cascade Range, 45 miles (70 km) east-southeast of Portland. It is a dormant volcano that last erupted about 1865, with minor steam and ash (tephra)
3. Volcanoes are often found at meeting points of “tectonic plates”. These plates are pieces of the Earth’s surface that fit together just like a jigsaw puzzle.4. Volcanoes can also occur over “mantle plumes”.Ever heard of mantle plumes? They’re super-hot areas of rock inside the ...
A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from below the surface.Volcanoes are generally found where tectonic plates are diverging or converging. A mid-oceanic ridge, for example the Mid-Atlantic...
Volcanoes of New Zealand | John Seach New Zealand sits on the boundary of the Pacific and Australian tectonic plates. Active volcanoes are only located on the North Island, and offshore islands. New Zealand Antarctic territory includes volcanoes at Balleny Islands, Mt Erebus, and Mt Melbourne....

These fiery peaks have belched up molten rock, hot ash, and gas since Earth formed billions of years ago.
The eruption devastated southern and central Kyushu and left the present-day caldera. Younger cones have grown inside the caldera, including Iwo-dake, a rhyolitic lava dome at the eastern end of Tokara-Iwo-jima. Kikai's frequent historical activity were small to medium explosive eruptions mainly ...
