Other articles where Stratovolcano is discussed: volcano: Stratovolcanoes: Stratovolcanoes such as Mayon Volcano in the Philippines, Mount Momotombo in Nicaragua, and Ol Doinyo Lengai in Tanzania are steep cones built by both pyroclastic and lava-flow eruptions. Stratovolcano Steep, conical volcanoes built by the eruption of viscous lava flows, tephra , and pyroclastic flows , are called stratovolcanoes. The descent of the oceanic plate causes the release of trapped water from hydrated minerals and porous rock, into the mantle rock in the area above the oceanic slab.

The lava that flows from them is viscous, and cools and hardens before spreading very far. Shield volcanoes have long gentle slopes causd by highly fluid lava flows of basalt ie Hawaiis Kilauea. Unlike shield volcanoes, stratovolcanoes have a steep slope and explosive eruptions every now and then. Volcano - Volcano - Stratovolcanoes: Stratovolcanoes such as Mayon Volcano in the Philippines, Mount Momotombo in Nicaragua, and Ol Doinyo Lengai in Tanzania are steep cones built by both pyroclastic and lava-flow eruptions.

As nouns the difference between volcano and caldera is that volcano is a vent or fissure on the surface of a planet (usually in a mountainous form) with a magma chamber attached to the mantle of a planet or moon, periodically erupting forth lava and volcanic gases onto the surface while caldera is (vulcanology) a large crater formed by a volcanic explosion or by collapse of the cone of a volcano.
