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 .
It was historically considered to be the largest volcano on Earth until the submarine mountain Tamu Massif was discovered to be larger. [4] 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 ...
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)
Olympus Mons (/ ə ˌ l ɪ m p ə s ˈ m ɒ n z, oʊ-/; [4] Latin for 'Mount Olympus') is a large shield volcano on Mars.It is over 21.9 km (13.6 mi; 72,000 ft) high as measured by the Mars Orbiter Laser Altimeter (MOLA), [5] about 2.5 times the elevation of Mount Everest above sea level.
The Medicine Lake shield rises about 3,900 ft (1,200 m) above the Modoc Plateau to an elevation of 7,795 ft (2,376 m). Lavas from Medicine Lake Volcano are estimated to be at least 140 cu mi (600 km 3) in volume, making Medicine Lake the largest volcano by volume in the Cascade Range (Newberry Volcano in Oregon has the second largest volume).
Maat Mons has a large summit caldera, 28×31 km in size.Within the large caldera, there are at least five smaller collapse craters, up to 10 km in diameter.A chain of small craters 3–5 km in diameter extends some 40 km along the southeast flank of the volcano, but rather than indicating a large fissure eruption, they seem to also be formed by collapse.
Axial Seamount is a shield volcano, which means it's shaped like a shield rather than a steep-sided cone volcano. Its caldera at the top is a few miles wide and long, and about 300 feet deep.
It is a shield volcano with a diameter of 60–70 kilometres (37–43 mi) [15] or 60–80 kilometres (37–50 mi) [12] and an estimated volume of 2,500 cubic kilometres (600 cu mi). [17] The summit of Emi Koussi is formed by two overlapping calderas , which together form a [ 18 ] 15-by-11-kilometre (9.3 mi × 6.8 mi) wide [ 15 ] elliptical ...
