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 ...
The northern volcano, Camp Hill, began forming when the MEVC was still partially covered by glacial ice. Eruptions under the glacial ice formed a circular meltwater pond which quenched the erupting lava and caused phreatic explosions, resulting in fractured and churned debris accumulating around the erupting vent to create a broad tuff ring.

The Giant's Causeway (Irish: Clochán an Aifir) [1] is an area of approximately 40,000 interlocking basalt columns, the result of an ancient volcanic fissure eruption. [3] [4] It is located in County Antrim on the north coast of Northern Ireland, about three miles (4.8 km) northeast of the town of Bushmills.
The craters were formed during a series of eruptions associated with a basaltic dyke intrusion from the volcanic system of Bárðarbunga around the year 877. [ a ] These eruptions, like those of the neighbouring Veiðivötn , were from about 65 kilometres (40 mi) (or 42 kilometres (26 mi) [ 5 ] ) long volcanic fissures within the area of a lake.
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.
There are high temperature geothermal areas associated with the Hofsjökull central volcano, its northern fissure swarm, and Kerlingarfjöll to its south. [6] A sulfurous jökulhlaup occurred in the summer of 2013, from the Hofsjökull glacier with a new ice cauldron being formed at the north-east edge of the Hofsjökull central volcano's ...
The name is perfect, even while it dramatically undersells this geologic wonder in remote southeast Oregon. It's called Crack in the Ground, a volcanic fissure 70 feet deep and two miles long that ...
Both volcanoes are part of the Eastern volcanic zone of Iceland, are over the Iceland mantle plume, [18] and are related to two associated parallel fissure systems with crater rows extending to the south east; the 25 km (16 mi) long Laki–Grímsvötn fissure system and the 30 km (19 mi) long Rauðhólar-Eldgígur fissure system.
