Four days after its most recent eruption, Alaska’s Mount Redoubt erupted again on March 26, 2009. The volcano sent a plume of ash at least 65,000 feet above sea level, said the National Weather Service. The Alaska Volcano Observatory reported that the eruption also sent a lahar, a flood of rock and water, into the Drift River Valley.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this image of the aftermath of the eruption at 2:40 p.m. local time, a little more than five hours after the large eruption. A cloud of tan ash extends from the volcano south and east. The ash colors the clouds south of Anchorage—an indication that the volcanic plume rose above the cloud level. A dark-colored streak extends south of the volcano where ash had fallen on the snow.
