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)
Selected geological features near the Skjaldbreiður shield volcano.(red outline). Light violet shading shows the current surface area of the Skjaldbreiður lava flows. Shading also shows: calderas, central volcanoes and fissure swarms, subglacial terrain above 1,100 m (3,600 ft), and seismically active areas. Clicking on the image enlarges to ...
This causes enormous lava flows, accounting for 80% of Venus' surface area. Many of the mountains are large shield volcanoes that range in size from 150–400 km (95–250 mi) in diameter and 2–4 km (1.2–2.5 mi) high. More than 80 of these large shield volcanoes have summit calderas averaging 60 km (37 mi) across. [39]
Fumarole Butte is a shield volcano in central Juab County, Utah, United States. [1] Built during the Quaternary period, it is composed of basaltic andesite. It stands 207 meters (679 ft) in height and has a diameter of 12 kilometers (7 mi). Under the volcano lies Crater Bench, the result of an eruption of basaltic andesite.
The volcano dates from the Mid-Holocene, is - following B. Hróarsson - about 6,000 years old, slightly younger than the Selvogsheiði, another shield volcano on Reykjanes peninsula, [1] whereas Sinton defines its age as “finiglacial”, i.e., from the beginning of Holocene. [2] It covers about 160km2, and its volume is about 10km3. [1]
Kīlauea (US: / ˌ k ɪ l ə ˈ w eɪ ə / ⓘ KIL-ə-WAY-ə, Hawaiian: [kiːlɐwˈwɛjə]) is an active shield volcano in the Hawaiian Islands. It is located along the southeastern shore of Hawaii Island. The volcano is between 210,000 and 280,000 years old and grew above sea level about 100,000 years ago.
Mount Wrangell, (Ahtna: K’ełt’aeni, or K’ełedi when erupting) [3] is a massive shield volcano located in Wrangell-St. Elias National Park and Preserve in southeastern Alaska, United States. The shield rises over 12,000 feet (3,700 m) above the Copper River to its southwest.
