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.
Examples of shield volcanoes are Kilauea and Mauna Loa (and their Hawaiian friends), Fernandina (and its Galapagos galÃ¡pagos), Friends, Karthala Erta, Ale, Tolbachik, masaya and many. Others here are 4 of the volcanoes that comprise the big island Of'hawai. ihield 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.
