Icelandic
Eruptions May Disrupt Air Traffic For
Months
Volcanic eruptions in Iceland which this
week caused thousands of flights to be
canceled may continue for months, disrupting
European air traffic as ash is sporadically
blown above the continent’s busiest
airports. More than 20,000 flights have been
grounded after an April 14 eruption of the
1,666-meter (5,466-foot) Eyjafjallajökull
volcano sent dust billowing across thousands
of miles of European airspace and closed
terminals from Dublin to Moscow. “It could
go on for months,” Sigrun Hreinsdottir, a
geophysicist at the University of Iceland,
said in a telephone interview from
Reykjavik. “From what we’ve seen, it
could erupt, pause for a few weeks, and then
possibly erupt again.” Canceled flights
are costing carriers about $200 million a
day, the International Air Transport
Association estimates. Restrictions over
most of the U.K. will remain in place until
1 p.m. at least, shutting London Heathrow,
Europe’s busiest airport, and while
terminals have reopened in Scotland and
Ireland, others have closed as the cloud
drifts southeast. Flights have been halted
amid concern that the ash plume could damage
engines or parts such as speed sensors. The
finest material from the blast is formed of
dust akin to glass, which can melt and
congeal in a turbine, causing it to stop,
said Sue Loughlin, head of vulcanology at
the British Geological Survey.
