Definitions:

Fissure Eruption

A volcanic eruption that occurs when magma rises through and erupts onto the surface in a long fissure.

Lava Fountain

A fountain of molten lava propelled into the air by pressure and escaping gases.

Volcanic Dome

A rounded mound formed over a volcanic vent, created by the slow extrusion of viscous lava from a volcano.

Fissure

1. A fracture or crack on the land surface, such as that which forms by differential subsidence. 2. A magma-filled fracture in the subsurface that typically solidifies into a dike, or a linear volcanic vent erupting onto the land surface.
