Category A type of volcano . Description Built up by layers of lava flows from typically effusive eruptions, these eruptions commonly commence from central vents or at fissures. Under moderate to low eruption rates, shield volcanoes develop their most typical shield-like shape. Plan view : ranges...
A shield volcano is a broad volcano with gentle sides composed of basaltic lava. Mauna Loa of Hawaii Island is the largest shield volcano.
volcano eruption A shield volcano like Mauna Loa owes its shape to the way the lava erupts from a vent in the earths crust that begins as a fissure, or crack.Pockets of superheated magma well up from beneath the crust, causing it to bulge upward. As the sea floor bulges from the movem...
The basaltic lava that creates shield volcanoes gives it a different shape compared to other volcanoes. It flows quickly and covers more ground, which gives the shield volcano a broad surface. Each time the volcano erupts, more basaltic lava flows over the hardened surface to create another ...
These eruptions will usually have ground flows of lava that is capable of traveling great distances. Because the flows travel a longer distance, the individual sheets of lava are generally thinner. These longer lava flows from the eruptions are what gives the shied volcano their distinctive shape....
Despite the simplicity of the model, the quality of the fits and the internal consistency of the results are reasonable, encouraging development of more advanced models linking shield volcano shape to rheological properties of lavas and their characteristic time-scales of emplacement....
The shape, size, and position of the inadvertent-touch-prevention shielding area are determined according to the pressing states and positions of the grip support-point and the grip hold-point, and said shielding area is used for shielding a conventional touch operation or the like. 握持靠点也...

volcano, constructed from massive lava flows that emanated from the volcano centre to form a broad, shield-like shape. The volcano has anomalously low slopes, probably due to the high effusion rates of the erupting lavas. We suggest that the Tamu Massif could be the largest single volcano on...
