WebFormation [ edit] A lava tube is a type of lava cave formed when a low- viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Tubes form in one of two ways: either by the crusting over of lava channels, or from pāhoehoe flows where the lava is moving under the surface. WebStratovolcanoes.
