This true-color image over Kodiak Island, Alaska, shows a plume of resuspended volcanic ash (tan pixels) extending southeastward from the mainland out over the Gulf of Alaska. According to the Alaska Volcano Observatory, strong winds in the Katmai National Park and Preserve region are picking up old, loose volcanic ash and blowing it toward the southeast. Although this particular plume is not the result of an active volcano, airplane pilots should consider resuspended ash just as hazardous as the ash from an actively erupting volcano. This scene was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS), aboard NASA’s Aqua satellite, on September 21, 2003.
