Iceland is located on the Mid-Atlantic Ridge.
The North-American and Eurasian plates move apart- called constructive
plates.
This causes magma to rise to the surface and form volcanoes.
The latest eruption occurred under a glacier.
The water cooled the lava quickly resulting in glass particles entering the
plume.

Why can’t we fly?- Which are true?
http://en.wikipedia.org/wiki/File:Turbofan3_Unlabelled.gif
The particles erode the fans of the
engines.
The aircraft is likely to be hit by lava.
Ash blocks the ventilation system, causing the engines
to overheat and shut down.
Ash can add significant weight to
the aircraft and change its balance.
Glass in the plume melts and coats the internal parts of the
engine.
The particles can sandblast the
windscreen making it difficult to land.
Gases from the volcano could cause
the pilots to pass out.
Ash can cause damage to instruments that measure
pressure and airspeed.
Pilots are unable to navigate due to the poor visibility.
