The eruption occurs about every 40 to 80 years. There are mostly freatomagmatické outbursts, as a result of contact with a hail of lava usually produces so. jökulhlaupy, that suddenly floods.

Katla is the source of pyroclastic flows, so called. tefry (approximately 6 to 7 cubic kilometers).

Katla has shown signs of unrest since 1999. Geologists are concerned that the eruption may occur anytime in the near future. The activity of the volcano is under constant surveillance, especially after the eruption Eyjafjallajökull glacier lying under the same name in March and April 2010. Eruption of the volcano near between geophysics raise concerns that could trigger the eruption of the volcano Katla
