What is a fissure eruption?
VolcanoesEruption types
Quick Answer
A fissure eruption happens when lava erupts from a long crack in the ground instead of a single volcano vent.
The Full Story
Fissure eruptions can produce enormous lava flows from a line of openings, sometimes stretching for kilometers. They are often associated with rifting or very fluid basaltic magma. One famous example is the 1783–1784 Laki eruption in Iceland, which opened a long fissure and released vast amounts of lava and gas. Such eruptions can have major regional effects, including air pollution and crop failures.
