Eyjafjallajokull

Eyjafjallajokull is a stratovolcano in southern Iceland completely covered by one of the country's smaller ice caps, lying north of Skogar and west of Myrdalsjokull, and reaching 1,651 meters at its summit, or 1,666 meters counting the ice on top. In March 2010 it produced a relatively modest fissure eruption at Fimmvorduhals, followed on April 14 by a far larger eruption from the ice-covered summit crater that threw volcanic ash several kilometers into the atmosphere. That ash cloud disrupted air travel across more than twenty countries in Europe for roughly a week, one of the most disruptive volcanic events to global aviation in modern history. By August 2010 the volcano was considered dormant again, though it continues to be monitored with infrasound sensors.
