Ash Plumes from Redoubt Volcano


Earth Observatory Images of Ash plumes ejected by Redoubt Volcano. Above image was acquired March 23, 2009
at 12:30am AKDT [Add 8 hrs for UTC.] The above Terra MODIS image was captured at 12:30 a.m.  March 23, just 16 minutes after the third large eruption. Two plumes of ash are visible: a long white plume reaching north, and a smaller one just northeast the volcano. Communities along the trajectory of the ash plume included Skwenta and Talkeenta. NASA images created by Jesse Allen, using data provided courtesy of the MODIS Rapid Response team.


The Aqua MODIS image  was captured four hours later, at 4:30 a.m. AKDT, just as the fifth large eruption began. At that time, the new ash plume was located directly over Mt. Redoubt.
