shield volcano

Glossaries

Term	Definition
shield volcano	A shield volcano is a type of volcano with a broad, flattened shape, formed by the accumulation of fluid lava flows that spread over large distances. A shield volcano is a volcano characterized by its broad, gently sloping dome shape, resembling an inverted shield. This type of volcano forms from the accumulation of basaltic lava flows, which are highly fluid and can spread over vast distances before solidifying. The low viscosity of this lava allows the eruptions to cover wide areas, resulting in gentle slopes and a very wide volcanic structure. Shield volcanoes are primarily associated with effusive eruptions, which are characterized by lava flows rather than explosive activity. Notable examples of shield volcanoes include Mauna Loa in Hawaii and Piton de la Fournaise on Réunion Island.
