After coming to life in December 2010—following more than 80 years of silence—Kizimen Volcano showed no signs of slowing down in February 2011.
This false-color satellite image shows a vigorous volcanic plume streaming northeast from the summit. The white portion of the plume is likely rich with steam, while the tan plume is primarily ash. To the northwest, forests that have not yet been coated with ash are red. The ground east of Kizimen is coated in newly-fallen ash that has not yet covered by snow. Several dark streaks lie to the south of the summit—probably traces of pyroclastic flows.
In contrast to the explosive eruptions of the previous week, ash emissions from Mount Redoubt became more frequent but confined to lower altitudes on March 30, 2009. The commercial satellite GeoEye-1 captured a high-resolution view of the volcano the same day.
