This list of shield volcanoes includes active, dormant and extinct shield volcanoes.Shield volcanoes are one of the three types [specify] of volcanoes. They have a short cone shape, and have basaltic lava which means the lava has low viscosity (viscosity is a measure of the ability for a liquid to flow)
A shield volcano is a type of volcano named for its low profile, ... Most mature shield volcanoes have multiple cinder cones on their flanks, the results of tephra ...
Lassen Volcanic National Park is one of the few areas in the world where all four types of volcanoes can be found: plug dome, shield, cinder cone, and stratovolcano. [4] The source of heat for the volcanism in the Lassen area is subduction of the Gorda Plate diving below the North American Plate off the Northern California coast. [5]
All four types of volcanoes found in the world—shield, composite, cinder cone, and plug dome—are represented in Lassen Volcanic National Park. [2] The Cascade Volcanoes are fed by heat generated as the Gorda and Juan de Fuca tectonic plates are being subducted below the much larger but lighter North American Plate.
A cinder cone (or scoria cone [1]) is a steep conical hill of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or scoria that has been built around a volcanic vent. [ 2 ] [ 3 ] The pyroclastic fragments are formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent.
According to Hildreth (2007), Belknap Crater is a broad, low-angled shield volcano compared to other mafic (rich in magnesium and iron) volcanic cones. [7] Belknap's summit cone rises about 400 feet (120 m) above the base shield volcano, [8] and the volcano itself rises about 1,600 feet (490 m) above its surroundings. [9]
All stratovolcanoes and shield volcanoes have a tendency to form a cone at the surface. However, stratovolcanoes are able to form steeper sides whilst shield volcanoes only form very flat cones. The reason for this is that stratovolcanoes are composed largely of solid, eruptive material, whereas shield volcanoes are built up mainly by fluid ...
The 5.5 km (3.4 mi) wide island is a symmetrical shield volcano cone capped by central scoria cones, reaching a height of 260 m (850 ft). [ 2 ] [ 3 ] Rangitoto is the youngest and largest of the approximately 50 volcanoes of the Auckland volcanic field , having erupted in two phases about 1450 CE and 1500 CE [ 4 ] [ 5 ] and covering an area of ...
