Iceland volcano could wreak havoc with air travel

Aug. 20, 2014, Reykjavik, Iceland - The world's airline industry is on alert after Icelandic authorities have raised the alarm over a sudden flurry of small earthquakes that could cause one of the country's largest volcanoes to erupt.

The Icelandic Meteorological Office warned Tuesday it has detected
more than 3,000 minor earthquakes since Saturday along a fault line in
the country's centre.

Much of the activity is clustered around Bardarbunga — a subglacial
stratovolcano under Iceland's largest glacier. "Several of these events
were larger than magnitude 3," the office warns, with one touching 4.5
on the Richter scale — the strongest in that region since 1996 —
although none has been that strong in the past 24 hours.


Although seismic activity in Iceland is routine, the sudden increase
in number and intensity has volcanologists worried, because the last
time similar activity was seen was in April 2010, when Eyjafjallajokull erupted and the plume of ash and smoke grounded transatlantic air travel for the better part of a month.



Seismologists say magma is moving horizontally, not yet vertically,
and "no signs of migration towards the surface or any other signs of
imminent or ongoing volcanic activity have been detected so far."


However, the aviation alert level has been raised to the second-most severe level as a precaution.


"Presently there are no signs of eruption, but it cannot be excluded
that the current activity will result in an explosive subglacial
eruption, leading to an outburst flood … and ash emission," the office
