A fissure vent, also known as a volcanic fissure, eruption fissure or simply a fissure, is a linear volcanic vent through which lava erupts, usually without any explosive activity. The vent is often a few metres wide and may be many kilometres long. Fissure vents can cause large flood basalts which run first in lava channels and later in lava ...
A volcanic fissure and lava channel. A fissure vent, also known as a volcanic fissure or eruption fissure, is a long volcanic vent through which lava erupts. Fissure vents are connected to deep magma reservoirs and are typically found in and along rifts and rift zones. [14] They are commonly associated with shield volcanoes.
Crack in the Ground marks the western edge of this small, volcano-tectonic depression. The crack is the result of a tension fracture along a hingeline produced by the draping of Green Mountain lava flows over the edge of upthrown side of the concealed fault zone. The fissure is located at the southwest corner of Four Craters Lava Field. [2]
The name is perfect, even while it dramatically undersells this geologic wonder in remote southeast Oregon. It's called Crack in the Ground, a volcanic fissure 70 feet deep and two miles long that ...

Volcanic outbreaks in the Reykjanes peninsula are so-called fissure eruptions, which do not usually cause large explosions or significant dispersal of ash into the stratosphere.
Some of the eruptive structures formed during volcanic activity (counterclockwise): a Plinian eruption column, Hawaiian pahoehoe flows, and a lava arc from a Strombolian eruption. Several types of volcanic eruptions—during which material is expelled from a volcanic vent or fissure—have been distinguished by volcanologists.
A volcano erupted in southwest Iceland at around 8 a.m. local time. The Icelandic Meteorological Office (IMO) reported that the southernmost part of the fissure was “about 900 m from the town of ...
