Fissure Volcanoes - U.S. National Park Service
Sep 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
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 - Wikipedia
A fissure is a long, narrow crack opening along the surface of Earth. The term is derived from the Latin word fissura, which means 'cleft' or 'crack'. Fissures emerge in Earth's crust, on ice sheets and glaciers, and on volcanoes.
How Volcanoes Work - fissure eruptions
As fluid, gas-poor basaltic magma rises up through a fissure, it is extruded at the surface as a wall of incandescent, liquid-to-plastic fragments known as a curtain of fire. Two such eruptions are shown below from extrusive events on the Kilauea volcano, Hawaii.

Fissure volcanoes are essentially neither constructional nor excavational. They do not build edifices or experience explosive eruptions that form craters or experience subsidence. Related Links

Mar 3, 2022 · A volcano on Earth is a vent or fissure in the planet's crust through which lava, ash, rock and gases erupt. A volcano is also a mountain formed by the accumulation of these eruptive products.
2018 lower East Rift Zone Eruption and Summit Collapse at Kīlauea
Nov 24, 2023 · An intrusion of magma into Kīlauea Volcano's lower East Rift Zone resulted in an eruption in Leilani Estates in the lower Puna District on the Island of Hawai‘i. The first four fissures to erupt in the subdivision are shown here on May 4, emitting copious amounts of hazardous sulfur dioxide gas.

Jul 5, 2023 · Fissure Volcanoes. Volcanoes that have an elongated fissure as their vent. Some fissure volcanoes lack substantial edifices as they may erupt fluid lava flows that may travel great distances from the vent.
Fall into a burning (curtain) of fire with fissure eruptions
Jul 11, 2023 · It's a classic example of an eruption of relatively fluid lava simultaneously at multiple points along a fissure in the earth, resulting in "curtains of fire". These fascinating phenomena provide a spectacular glimpse into the geologic processes driving eruptions.
