Last year: Southern Iceland's Eyjafjallajokull glacier sent ash into the air in April last year bringing Europe to a virtual standstill. The 1783 eruption of the Laki volcano spewed a toxic cloud over Europe, killing tens of thousands of people. Crops failed and famine spread. In April 2010, the Eyjafjallajokull eruption prompted aviation officials to close Europe's air space for five days out of fear that the ash could harm jet engines.
Iceland volcano: New quakes raise concern over large eruption. Read more about sharing. A volcanic system close to Iceland's Bardarbunga's volcano was hit by a magnitude 4.5 earthquake in the early hours of Wednesday. It adds to concerns that magma from Bardarbunga could feed into the nearby Askja volcano. British and Icelandic scientists say that 50 million cubic metres of molten rock has moved in a 24 hour period. If it continues to head north, it could link up with the Askja system and trigger a large eruption.
