Wrangell reported activity





Event Name : Wrangell 2012/3

Start:March 2012 Observed

Fumarolic or hydrothermal activity: BibCard
Eruption Type:Not an eruption.

Description: From Herrick and others (2014): "On March 11 [2012], observers in Glennallen noted 'puffs of steam' and called the State of Alaska Department of Homeland Security and Emergency Management office with their concerns. AVO was also contacted and analysts were able to see small plumes above known fumaroles in satellite images.

"On March 20, a citizen noticed unusually rigorous steaming at Wrangell while driving towards to volcano from Valdez. Steam rose from the summit as well as a location on the southwestern flank at about 3,000 m (10,000 ft) ASL and the citizen described the volcano as looking like 'a pressure cooker shot through with nails'. There also were calls to the observatory on June 21 due to concerns about substantial plumes visible from various vantage points in the Copper River basin. No other evidence of significant volcanic unrest was detected, thus AVO concluded these events were likely generated by normal fumarolic activity. No further response activities were required."
