Today, British civil aviation authorities ordered the country's airspace closed as of noon, due to a cloud of ash drifting from the erupting Eyjafjallajökull volcano in Iceland. The volcano has erupted for the second time in less than a month, melting ice, shooting smoke and steam into the air and forcing hundreds of people to flee rising floodwaters. The volcanic ash has forced the cancellation of many flights and disrupted air traffic across northern Europe, stranding thousands of passengers. Collected here are photos of the most recent eruption, and of last month's eruptions, which were from the same volcano, just several miles further east. (18 photos total)
