Mauna Kea, HawaiÊ»i, a shield volcano on the Big Island of Hawaii. A shield volcano is a type of volcano usually built almost entirely of fluid magma flows. They are named for their large size and low profile, resembling a warrior's shield lying on the ground.This is caused by the highly fluid lava they erupt, which travels farther than lava erupted from stratovolcanoes.hield volcanoes are distinguished from the three other major volcanic archetypesâ stratovolcanoes, lava domes, and cinder cones âby their structural form, a consequence of their unique magmatic composition.
Shield Cone Volcano. Shield Cone Volcanoes are volcanoes with gradual sloping sides, wide bases, and flat craters. They are volcanoes that are created by freely flowing lava, or quiet eruptions. Mauna Loa Volcano, Hawaii. Photograph by D. Little. Cinder Cone Volcano.Cinder Cone Volcanoes are volcanoes with steep sides, and bowl shaped craters. These volcanoes are created by a buildup of cinder and ash. The Cinder Cone Volcano is usually the most dangerous type of volcano because it tends to explode when it erupts.hese volcanoes are formed by lava flows and volcanic rocks. Another name for Composite-Cone Volcanoes are Stratovolcano. Composite-Cone Volcanoes are know to have two kinds of eruptions, free-flowing, or slow moving, and violent erupts.
