Shield volcano - Wikipedia
https://en.m.wikipedia.org/wiki/Shield_volcano
WebA 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.

WebNational Park Shield Volcanoes. At least 13 national parks contain shield volcanoes, including: Hawai’i Volcanoes National Park contains parts of Mauna Loa and Kīlauea, two of the most active shield volcanoes on Earth. Although these volcanoes are adjacent to one another, they have separate magma systems and are thus independent of one another.

WebSep 28, 2023 · Shield volcanoes are a type of volcano that erupts 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 at large distances. For a shield volcano, violent explosions are possible. But they’re more common for stratovolcanoes.

WebIn volcano: Shield volcanoes. Structures of this type are large dome-shaped mountains built of lava flows. Their name derives from their similarity in shape to a warrior’s shield lying face up. Shield volcanoes are usually composed of basalt. Small shield volcanoes may form rapidly from almost continuous….

WebShield 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.

WebSHIELD VOLCANOES. Shield volcanoes are broad, low-profile features with basal diameters that vary from a few kilometers to over 100 kilometers (e.g., the Mauna Loa volcano , Hawaii). Their heights are typically about 1/20th of their widths. The lower slopes are often gentle (2-3 degrees), but the middle slopes become steeper (~10 degrees) and ...

WebShield volcanoes are exactly what the nomenclature implies – very large, broad, shield-like structures that have a low aspect ratio (i.e., much wider than they are tall). These volcanoes form when a centralized vent produces low-viscosity flows over a long period of time ( Walker, 2000: 284).
