Description: From McGimsey and others (1995): "On March 3 [1992], a plume-like cloud seemingly originating from Mount Mageik appeared on two successive National Oceanographic and Atmospheric Administration (NOAA) satellite images prompting the Federal Aviation Administration to issue a warning to aircraft of a possible eruption. AVO responded by compiling pilot reports, analyzing the satellite imagery, obtaining seismic information from the research seismic net in Katmai, issuing an information release, and then dispatching staff on an observation flight to assess the situation; AVO did not, however, confirm an eruption. Pilots reported smelling sulfur dioxide but detected no gas or ash plume. The seismic data indicated no unusual seismicity had occurred in the Katmai volcanic group. Airborne AVO observers found no evidence of eruptive activity at Mt. Mageik or in the areas downwind from the volcano. AVO then issued an update announcing that no eruption had occurred. The incident was deemed useful in exercising AVO's response to a potential eruption in a remote area."
