A volcanic eruption in
Iceland has sent ash across northern Europe Airlines have stopped or changed the flights across the Atlantic Ocean, leaving hundreds
of passengers stuck in airports.
Grimsvoto is one of the largest and most active volcanoes
in Europe. What makes Grimsvoto different is
that it lies under a huge glacier(冰川)of ice up to 12 meters
thick. The hot volcano heats up the ice above it, which then forms a layer(层)of water between
the glacier and the volcano . This layer of water puts pressure on the volcano,
keeping it stable, As the water flows out from under the glacier, the pressure
lifts. The lava(岩浆)from the volcano then comes up to the surface. This is
exactly what happened today.
Now,
airlines have to make changes to their flights so as not to fly through the
clouds of volcanic ash. According to KLM, one of Europe’s
biggest airlines, airplanes cannot go under the cloud or over it. Going through
the cloud can result in ash getting stuck in the airplane’s engines, causing
damage to the plane.
The
eruption has also caused problems for animals in Iceland. The volcano left ash and
sharp, glass-like rocks all over the countryside. Farmers are keeping their
animals inside to stop them from eating ash- covered grass to the sharp
objects.
