In this volcano there were two or more discrete magmatic sources involved, with magma of different composition. At this point the eruption was explosive but maanagement the key ingredient missing was water and volcanologists feared that the eruption may extend under the glacier- they were right!

That means that the countries affected by this hazard responded by themselves or collectively, and had the capacity to do so.

Thde glacial water instantly cooled the erupting lava causing it to shatter into minute shards of glass and ash which were propelled s metres into the atmosphere by the force of the explosions. LEDCs were also badly affected, with Kenya being a great example.

This fine grained ash poses a problem to airplanes, as it can affect many systems when it enters the engines and even turn to a glassy substance because of the heat of the jet engine.

Scientists were very concerned at the time of the eruption that this eruption could be a precursor or warning sign of a much larger eruption of the historically more active and dangerous Katla. It was also categorised as both a fissure and explosive eruption.
