Aniakchak (United States, Alaska Peninsula): Volcanic Ash Advisory Center Anchorage (VAAC) issued the following report: NO ERUPTION.
…3 Aug:
The Alaska Volcano Observatory (AVO) reported that strong winds blowing to the north in the region north of Aniakchak and east of Port Heiden have picked up loose volcanic ash and carried it to the north today. A dense cloud of possible resuspended volcanic ash was observed near ground levels in a web camera at Port Heiden. Satellite views confirm that this cloud has been drifting to the north approximately 200 km. The height of this cloud is not known, but resuspended ash clouds are typically from sea level up to 5 km in altitude.
This phenomenon is not the result of volcanic activity and usually occurs seasonally in the spring and fall during times of high winds and dry snow-free conditions in volcanic areas of Alaska.
