Eyjafjallajökull Volcano Erupts, Grounding European Flights
Iceland's Eyjafjallajökull volcano had been relatively quiet for nearly two centuries before renewed seismic activity began in early 2010. A flank fissure eruption occurred in March, but on April 14 the summit caldera erupted explosively beneath its ice cap, sending a plume of fine volcanic ash more than eight kilometers high. Westerly winds carried the glass-rich ash southeast across northern Europe, where it posed severe risks to jet engines. Aviation authorities closed airspace in over twenty countries for several days, canceling more than 100,000 flights and stranding millions of passengers. The disruption represented the largest shutdown of European air travel since World War II.
