Shield Volcanoes. Shield volcanoes are the largest volcanoes on Earth that actually look like volcanoes (i.e. not counting flood basalt flows). The Hawaiian shield volcanoes are the most famous examples. Shield volcanoes are almost exclusively basalt, a type of lava that is very fluid when erupted A shield volcano is a wide volcano with shallowly-sloping sides. Shield volcanoes are formed by lava flows of low viscosity - lava that flows easily. Consequently, a volcanic mountain having a. Shield Volcanoes are one of the three types 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 Shield volcanoes are a type of volcano that tend to erupt basalt lava. Because basalt has a low viscosity (more watery), it can flow on the surface better. So when these types of volcanoes erupt, lava flows outwards large distances. For a shield volcano, violent explosions are possible. But they're more common for stratovolcanoes A shield volcano is a large volcano, often many miles in diameter, with gently sloping sides. The lava—the molten or liquid rock expelled during an eruption—from shield volcanoes is largely basaltic in composition and it has a very low viscosity (it's runny)

A shield volcano is the largest type of volcano on Earth, with low viscosity lava flows and a wide broad shape. The low viscosity, runny, nature of the lava means it travels in streams far from the source and covers many square miles. The largest volcano in the entire world, Mauna Loa in Hawaii, is a shield volcano A shield volcano is the largest kind of volcano that erupts a thin, low-viscosity, basaltic lava gently and over a large area The largest and hottest shield volcano on Earth was revealed by researchers from the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology (SOEST).

Shield Volcano Definition . A shield volcano has a broad shape due to having been formed by multiple lava flows. This type of volcano is formed as a result of lava flowing over a period of time. Because there are multiple flow points for the lava, a gently sloping surface is created. This surface resembles a warrior's shield, which is why they are described as shield volcanoes A shield volcano is a broad volcano with sloping sides that is formed mainly out of runny lava that flows out of its central summit vent. Examples of Shield Volcano: Mauna Loa in the Island of Hawaii, Wolf volcano in Galapagos Islands and Nyamuragira in the Democratic Republic of Cong The island of Surtsey []. Surtsey is the youngest shield volcano of Iceland and originated in a series of eruptions which started with a submarine phase in 1963 and ended by subaerial production of lava and ash in hawaiian style in 1967. Since then, heat within has changed the volcanic ash into erosionresistant tuffstone and the sea has eroded away other parts of the island Shield volcano definition, a volcano formed entirely from accumulated flows of fluid lava, growing a few feet at a time and giving the volcano its broad, gently sloping profile. See more A shield volcano is usually built up from highly fluid magma flows, which results in a volcano with a low profile that is spread over a large area, similar to the shield of a warrior if it were lying on the ground. The width of a shield volcano is usually 20 times its height, on average, but that doesn't mean that they do not reach high altitudes

A shield volcano is a type of volcano usually built almost entirely of fluid lava flows. They are named for their low profile, resembling a warrior's shield lying on the ground.This is caused by the highly fluid (low viscosity) lava they erupt which travels farther than lava erupted from stratovolcanoes.
