Iceland Volcanic Eruption May Ignite Geological Chain Reaction

April 15 (Bloomberg) -- The Icelandic volcano that erupted for the second time in four weeks may ignite a geological chain reaction with another volcano nearby, potentially extending a disruption to air traffic as ash plumes block flight paths.
The Eyjafjallajokull volcano in southern Iceland is adjacent to the Katla volcano, increasing the risk of a second eruption, said Ármann Höskuldsson, a volcanologist at the Institute of Earth Sciences at the University of Iceland. The Eyjafjallajokull last erupted in 1821 and remained active for two years, according to the researcher.
“It is a beautiful volcano, but not when it’s erupting,” Höskuldsson said. “It might be better tomorrow, but it could take a few days.”
Iceland sits on an oceanic ridge in the Atlantic that provides a continuous flow of magma, keeping the crust warm and providing natural energy. Iceland has more than 200 volcanoes and more than 600 hot springs. The volcano, located in a thinly populated part of Iceland, will likely spew ashes for a couple of days before lava emerges, according to the university.
The island is home to 320,000 residents. Settlers arrived in Iceland around 874 on sail-powered wooden longships. The country came under Norwegian control in 1262 and then under Danish dominion in 1380. It gained autonomy 90 years ago and became fully independent from Denmark in 1944. Iceland made headlines in the last year after its financial system cratered.
Wandering Plume
The extent and duration of the ash plume depends on weather conditions and the length of the eruption, said Sarah Holland, a spokeswoman for the U.K. Met Office. The band of ash now covers most of Norway, Scotland, northern and central England, as well as parts of Ireland, Sweden, Finland and Russia, according to the Met Office’s volcanic ash advisory service.
The plume is projected to spread east and south, extending over most of the British Isles, Scandinavia, the Benelux countries, Germany, Poland, the Czech Republic and the Baltic states of eastern Europe over the next day, as well as parts of northern France and western Russia.
The ash will affect flight traffic as long as the thick plume is lingering at heights of between six and 10 kilometers, Höskuldsson said. European, U.S., and Asian air traffic was heavily disrupted today, with the U.K and Norway suspending all flights as the volcanic ash poses a risk of engine malfunction and impairment of cabin air quality.
