Event Type: Not an eruption
- Remobilized tephra - no eruption [1]
Description: From Orr and others, 2023: "Although no eruptive activity was detected at Redoubt Volcano in 2019, on August 16, strong winds entrained and resuspended ash near the volcano. The resuspended ash cloud was not seen in satellite imagery but was visible in webcam views, and PIREPs described it as reaching an altitude as high as 10,000 ft (3,000 m) ASL. The National Weather Service Alaska Aviation Weather Unit issued a significant meteorological weather advisory for aviators, but AVO received no reports of ashfall. The Aviation Color Code and Volcano Alert Level at Redoubt Volcano remained GREEN and NORMAL throughout 2019."
