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.
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 in southwest Iceland has finally erupted, spewing rivers of lava from at least a four-km-long fissure, weeks after scores of earthquakes jolted the Reykjanes peninsula.
Aerial footage showed streams of orange molten lava and clouds of gases spewing from a snaking fissure about 900 meters (half a mile) long. Tourists are told to stay away from an erupting volcano ...
NORTH OF SYLINGARFELL, Iceland (Reuters) -A volcano in southwestern Iceland erupted on Thursday for the third time since December, spraying streams of lava up to 80 metres (260 feet) into the air ...
Augustine Volcano (Alaska) during its eruptive phase on January 24, 2006. A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
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 ...
