A shield volcano is a type of volcano named for its low profile, resembling a shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity) lava, which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano.
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)
The lava's viscosity mostly determines the behavior of lava flows. While the temperature of common silicate lava ranges from about 800 °C (1,470 °F) for felsic lavas to 1,200 °C (2,190 °F) for mafic lavas, [ 16 ] its viscosity ranges over seven orders of magnitude, from 10 11 cP (10 8 Pa⋅s) for felsic lavas to 10 4 cP (10 Pa⋅s) for ...
Skjaldbreiður, a shield volcano whose name means "broad shield" Shield volcanoes, so named for their broad, shield-like profiles, are formed by the eruption of low-viscosity lava that can flow a great distance from a vent. They generally do not explode catastrophically but are characterized by relatively gentle effusive eruptions. Since low ...
Mauna Loa is a shield volcano with relatively gentle slopes, and a volume estimated at 18,000 cubic miles (75,000 km 3), [5] although its peak is about 125 feet (38 m) lower than that of its neighbor, Mauna Kea. [6] Lava eruptions from Mauna Loa are silica-poor and very fluid, and tend to be non-explosive.
About 17 square miles (45 square kilometers) of rock was produced in this lava flow. "Both Sif Mons and the volcanoes in Niobe Planitia are shield volcanoes, characterized by broad, gentle slopes ...
The Deccan Traps are a large igneous province of west-central India (17–24°N, 73–74°E). They are one of the largest volcanic features on Earth, taking the form of a large shield volcano. [2] They consist of many layers of solidified flood basalt that together are more than about 2,000 metres (6,600 ft) thick, cover an area of about ...
Kohala (mountain) Kohala is the oldest of five volcanoes that make up the island of Hawaii. Kohala is an estimated one million years old—so old that it experienced, and recorded, the reversal of Earth's magnetic field 780,000 years ago. It is believed to have breached sea level more than 500,000 years ago [1] and to have last erupted 120,000 ...
