What does lava erupt violently?
Such eruptions result when sufficient gas has dissolved under pressure within a viscous magma such that expelled lava violently froths into volcanic ash when pressure is suddenly lowered at the vent. ... This cloud may then collapse, creating a fast-moving pyroclastic flow of hot volcanic matter.
Where does lava erupt?
Lava is the most common form of material erupted from volcanoes that form oceanic islands like the Galápagos and Hawaiian Islands. Lavaflows are usually only 1-10 meters thick, but some flows can be as thick as 50-100meters, depending on the type of lava and the volume of the eruption.
