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 is a volcanic fissure about 2 miles (3.2 km) long [1] with depths measuring nearly 30 feet (9 m) below ground level [2] in Central Oregon, United States. The formation of the fissure occurred approximately between 700,000 and 12,000 years ago. [3] The eruptions from the Four Craters Lava Field were accompanied by a slight ...
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.
Puʻu ʻŌʻō. The 2018 lower Puna eruption was a volcanic event on the island of Hawaiʻi, on Kīlauea volcano's East Rift Zone that began on May 3, 2018. It is related to the larger eruption of Kīlauea that began on January 3, 1983, though some volcanologists and USGS scientists have discussed whether to classify it as a new eruption. [2]
Laki (Icelandic pronunciation: [ˈlaːcɪ] ⓘ) or Lakagígar ([ˈlaːkaˌciːɣar̥], Craters of Laki) is a volcanic fissure in the western part of Vatnajökull National Park, Iceland, not far from the volcanic fissure of Eldgjá and the small village of Kirkjubæjarklaustur. The fissure is properly referred to as Lakagígar, while Laki is a ...
However, fissure vents occur on both (mainly the west) sides of the volcano. [14] The volcano is 800,000 years old. [15]: 15 The volcano is fed by a magma chamber under the mountain, which in turn derives from the tectonic divergence of the Mid-Atlantic Ridge. It is part of a chain of volcanoes stretching across Iceland.
