It spewed ash and large amounts of sulfur dioxide gas—the highest levels ever detected from space, according to preliminary estimates from researchers at NASA's Goddard Space Flight Center. Astronauts on the International Space Station snapped this digital photograph of Nabro in January 2011, when all was still quiet. The horseshoe-shaped caldera stretches 8 kilometers (5 miles) in diameter and opens to the southwest. Two smaller calderas lie within the larger one. Gullies and channels scar the outer flanks, signs of many years of runoff. The inner edge of the caldera has steep cliffs, some as high as 400 meters.
