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 volcanoes are the largest of the three types of volcanoes,  built from basaltic lava flows and shaped like a gentle dome.  Cinder cone volcanoes have very steep slope â¦ s and reach heights of  300 meters or less, and are made from ejected lava.hey are produced by hotspots and mid-ocean ridge. Cinder-cone volcanoes are the second of the three types of volcanoes. Cinder-cone volcanoes. Cinder-cone volcanoes have explosive eruptions that release lava high in the air.
