Hekla volcano, possible one of Iceland's most active volcanoes, could be close to erupting, a University of Iceland geoscientist claims.
The most prominent sign of an impending eruption is bulging ground on the northern side of the volcano. This surface swelling indicates magma (molten rock) is rising under the volcano, pushing up the ground as it fills fractures and pipes beneath Hekla. According to GPS monitoring of the expanding surface, there is now more magma underneath Hekla than before the volcano's last eruption in 2000, University of Iceland geophysicist Páll Einarsson said in a report published in the Icelandic newspaper Morgunblaðið yesterday (March 17).
