McGimsey and others (2004) report that "NWS observers in Cold Bay contacted AVO on the morning of November 7, 2001 to report a small steam plume originating from the south side of Pavlof; they also received several Pilot Weather Reports (PIREPS) describing the same observation. About a month later, on December 13, 2001, NWS personnel in Cold Bay reported steam issuing from a point about half-way down the south flank of the volcano. The plume rose to a height of about 6,000 ft (~1,830 m) before dissipating. A Pen Air pilot corroborated the report and added that the steaming was coming from a 'hill' on the southwest flank; this pilot added that he encountered a strong sulfur smell on a flight by the volcano that day. AVO detected no unusual seismicity or thermal anomalies. Based on conversations with the Pen Air pilot, AVO determined that the source of steaming was likely the fumarole field on nearby Mt. Hague, a late Pleistocene volcano with no historic activity."
