"One of the surprises was the complexity of the plumbing system," Sigmundsson said. Records show eruptions in 920, 1612 or 1613, 1821–23, and 2010. The behavior of Eyjafjallajökull might be typical for such moderately active volcanoes. The cause of Eyjafjallajökull's explosive eruption seemed to be the meeting of one body of magma, made up mostly of the common volcanic rock basalt, with another type of magma within the volcano, consisting largely of silica-rich trachyandesite. "The study gives the hope that with similar methods as we have used, we can better understand how volcanoes work and how they wake up before eruptions," Sigmundsson said. 23 24 25.
