Could an eruption like Laki happen again? Self says it not only could — but will — although such events are very difficult to predict. “There haven’t been enough of them to stack them up and say they happen every X number of years.”
What type of eruption is grimsvotn?
Grímsvötn is a basaltic volcano which has the highest eruption frequency of all the volcanoes in Iceland and has a southwest-northeast-trending fissure system. The massive climate-impacting Laki fissure eruption of 1783–1784 was a part of the same fissure system.
How old is Grímsvötn?

Is Iceland volcano about to erupt?
On March 19, 2021, the Fagradalsfjall volcano erupted after lying dormant for 800 years. Three months later, the volcano on Iceland’s Reykjanes peninsula is still spewing lava and expanding its flow field.
What type of eruption does Laki produce?
That is close to the average discharge of the Ohio River, but in basaltic lava form. This is why the Laki eruptions are considered close to a mini flood basalt eruption with such high rates of eruption. Most of the lava flows (90%) erupted in the first 5 months.
What effects did a volcanic eruption in 1783 have on mainland Europe?
In 1783, a mysterious dry fog enveloped the continent of Europe, blood-red sunsets were reported throughout the summer, and many reported a sulfuric smell, breathing difficulties and sore eyes. The Europeans were unaware that this was the result of a devastating event unfolding in Iceland.

Is the Grimsvotn volcano connected to the ACC?
On the other hand, because of the magma erupted showed strong connections to the Grímsvötn Volcanic System acc. to petrology studies, the 1996 as well as a former eruption there in the 1930s are thought to have taken place within Grímsvötn Volcanic system.
Where is the Grimsvotn fissure in Iceland located?
Grímsvötn (Icelandic pronunciation: [ˈkrimsˌvœhtn̥]; vötn = “waters”, singular: vatn) is a volcano with a (partially subglacial) fissure system located in Vatnajökull National Park, Iceland.
