Explanation:
Why did the picturesque
2010 volcanic eruption in Iceland create so much ash?
Although the large
ash plume was not unparalleled
in its abundance, its location was particularly
noticeable because it
drifted across such well-populated areas.
The
EyjafjallajĘkull
volcano in southern Iceland began erupting on 2010 March 20,
with a second eruption starting under the center of a small glacier on 2010 April 14.
Neither eruption was unusually powerful.
The second eruption, however, melted a large amount of
glacial ice which then cooled
and fragmented lava into gritty
glass particles that were carried up with the
rising volcanic plume.

lightning bolts illuminate
ash pouring out of the EyjafjallajĘkull volcano.
