Remember Fissure Vent
Fissure Vent Technical Terms
Fissure Vent: An opening in earth’s surface of a volcanic conduit in the form of a crack or fissure rather than a localized crater; a roughly linear crack or area along which lava, generally mafic and of low viscosity, wells up to the surface, usually without any explosive activity. The results can be an extensive lava plateau (e.g. Columbia River Plateau). Compare – crater [volcanic]. SW & GG
