Shield volcano - Wikipedia
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.
Shield volcano | geology | Britannica
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….
Shield Volcanoes - U.S. National Park Service
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.
Shield Volcanoes | Volcano World | Oregon State University
WEBShield 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 …
What is a Shield Volcano? - Earth How
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.
Shield Volcanoes Characteristics and Examples | Science Drill
WEBFeb 27, 2024 · Shield volcanoes are broad, low-profile volcanic landforms with gentle slopes that resemble a warrior’s shield or a broad low dome. They have mostly basaltic lava flow layers with minor pyroclasts. However, some are …
Shield Volcano - an overview | ScienceDirect Topics
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).
Geology and History of Kīlauea | U.S. Geological Survey - USGS.gov
WEBKīlauea Volcano is a shield volcano located on the eastern slope of Mauna Loa Volcano on the Island of Hawai‘i. The volcano is considered to be in the shield-building stage of Hawaiian volcanism. The Island of Hawai‘i with lava flows erupted in approximately the past 1,000 years shown in red.
How Volcanoes Work - shield volcanoes
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.
Geology and History of Mauna Kea | U.S. Geological Survey - USGS.gov
WEBNov 21, 2023 · Mauna Kea, the highest peak on the Island of Hawai‘i (4,207.3 m, 13,803 ft), is a shield volcano built upon the southern flank of Kohala Volcano's eastern rift zone. Mauna Kea is slightly higher than Mauna Loa (4,170 m, 13,681 ft), but its estimated volume (42,000 km 3) is about 55% less than that of Mauna Loa (95,000 km 3 ).
