Takk Hjörtur explains the consequences and frequencies of various Icelandic volcanoes erupting including Eyjafjallajökull, Katla, Hekla and Laki.

Explained is the relationship between eruptions of Katla and Eyjafjallajokull and some other Icelandic volcanoes.

There are plenty of volcanoes in Iceland.

Have you ever wondered what’s going on with all of these Icelandic volcanoes? Is it true that the eruption of one volcano can trigger another one to start up? Which of the big ones is really likely to erupt soon and which ones are not at all likely? Most importantly of all – how do you pronounce them!
