2011 Volcanic Activity In Stunning Pictures

Out of an estimated 1,500 active volcanoes around the world, 50 or so erupt every year, spewing steam, ash, toxic gases, and lava. In 2011, active volcanoes included Chile's Puyehue, Japan's Shinmoedake, Indonesia's Lokon, Iceland's Grímsvötn, Italy's Etna, and recently Nyamulagira in the Democratic Republic of Congo. In Hawaii, Kilauea continues to send lava flowing toward the sea, and the ocean floor has been erupting near the Canary Islands.

Collected below are scenes from the wide variety of volcanic activity on Earth over the past year.

Ash and rocks fell across a wide swath of southern Japan straddling the prefectures of Miyazaki and Kagoshima, as one of Mount Kirishima's many calderas erupted, prompting authorities to raise alert levels and call on for an evacuation of all residents within a 2 km (1.2 miles) radius of the volcano.
