Wrangell 1997/6
Start: June 1997 [1]
Event Type: Not an eruption
- Fumarolic or hydrothermal activity [1]
- Steam [1]
Description: From McGimsey and Wallace (1999): "On June 3, 1997, AVO received a pilot report of steam rising from the summit of Wrangell Volcano. Three weeks later, on June 24, another report described a steam plume rising up to 700 ft (~213 m) above the summit. No sign of activity was observed on satellite imagery and no mention was made in the AVO weekly update. Several active fumaroles in the summit caldera frequently produce steam plumes that are mistaken for eruptive activity."
