Volcano Katla

Volcano Katla is located in southern Iceland. The active volcano has shown signs of a possible eruption from late August 2016 and is larger than neighbouring Eyjafjallajökull; which caused enormous disruption to European air travel when it erupted in 2010.

Latest updates

Over fifty earthquakes were recorded on 29 September 2016, within the Katla caldera. Such seismicity is well above the daily average and it is the highest daily rate since 2011. The Icelandic Meteorological Office report that such summertime increases in activity are common. These follow two magnitude ~4.5 earthquakes which occurred in quick succession in the early hours of 29 August 2016. No measurable signs of volcanic tremor have yet been detected.

At this stage the Aviation Colour Code for Katla is 'Green' which means that the volcano is in a normal, non-eruptive state.

Past eruptions

Katla last erupted in 1918 and ejected 0.7 Km3 of material. This compares to the 0.25 Km3 of ash and other debris released by Eyjafjallajökull in 2010. Katla's prior eruptions have had a Volcanic Explosivity Index (VEI) of between 4 and 6 (on a scale of 0 to 8). In comparison, the Eyjafjallajökull 2010 eruption had a VEI of 4.
