Fissure Volcanoes - U.S. National Park Service
WEBSep 30, 2022 · Fissure volcanoes are produced by eruptions that occur along elongated fissures versus at a central vent. Fissure eruptions occur when magma-filled dikes intersect the surface. Fissure eruptions usually do not build substantial edifices, but instead feed lava flows that can travel great distances.
Fissure vent - Wikipedia
WEBA 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.
