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 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 - Wikipedia
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 …
Ocean Vent - Education
Apr 30, 2024 · An ocean vent sits over a deep fissure in the ocean floor. Ocean vents eject hot, often toxic, fluids and gases into the surrounding seawater. They often mark sites of tectonic activity, and create some of the most hostile habitats on Earth. Ocean vents are a type of hydrothermal vent.

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.
Fissure vent - (Volcanology) - Vocab, Definition, Explanations
A fissure vent is a linear volcanic feature through which lava erupts, characterized by a long crack or opening in the Earth's surface. These vents are significant in the formation of large volcanic landforms and can produce extensive lava flows that cover wide areas.
Fissure Vent - SpringerLink
Nov 20, 2015 · Fissure vents are fractures formed by tensile stresses and fed from below by subsurface dikes. Although explosive eruptions and lava effusion can occur simultaneously over long portions of a fissure, activity often migrates along a fissure over time and becomes localized at a few discrete points, where cones and craters are likely to form.
How Volcanoes Work - fissure eruptions
Linear vents with aligned spatter cones and spatter ramparts -- Fissure eruptions will generate a linear system of spatter cones and ramparts. If the eruption becomes concentrated on a single vent, then scoria cones may develop from more explosive Strombolian activity.
