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.
A shield volcano is a type of volcano characterized by its broad, shield-like profile. Unlike the steep, conical shape of stratovolcanoes, shield volcanoes have gentle slopes formed by the flow of low- viscosity basaltic lava.
Although shield volcanoes are the largest volcanoes on Earth, they do not form soaring mountains with conical peaks like composite volcanoes. Instead, they are broad volcanoes with gentle slopes and are shaped somewhat like a warrior’s shield lying flat on the Earth.
The shield volcano is an active volcano with a caldera that tends to erupt basalt lava. The name “shield volcano” originated from its Roman shield-like shape and is often broad and flatter than the other types of volcanoes.
What is a Shield Volcano? 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 Congo
Shield volcanoes are large, broad, low-profile volcanoes with gentle slopes. These volcanic landforms resemble a low profile, wide dome, cones, or warrior’s shield in their cross-section. They have a low angle slope of about 2-3° towards their base and lower flanks and up to 10° near their vent.
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.
