Flooding at Iceland volcano could signal eruption

REYKJAVIK, Iceland -- Torrents of water are pouring from a glacier that
sits atop Iceland's most active volcano, an indication that the
mountain is growing hotter and may be about to erupt, scientists said
Monday.
The flood that began Thursday at the Grimsvotn volcano is similar to
one in 2004 that lasted five days and ended with an eruption that
disrupted European air traffic, University of Iceland geophysicist Pall
Einarsson said.
In April, millions of air travelers around the world were grounded when
ash from Iceland's Eyjafjallajokul volcano led most northern European
countries to close airspace for five days.
There are no signs yet of the underground tremors that would signal an
eruption at Grimsvotn, Icelandic Meteorological Office geophysicist
Gunnar Gudmundsson said.
Grimsvotn lies under 650 feet (200 meters) of ice on the Vatnajokull
glacier in southeast Iceland. In addition to 2004, it erupted in 1998
and 1996, causing flooding to a largely uninhabited plain around it.
The flooding triggered by hot molten rock, or magma, from the volcano
has been expanding a lake underneath the glacier, building pressure
strong enough to send water pouring from under the ice cap.
A rugged island in the north Atlantic, Iceland is one of the world's
most volcanically active countries.
