Remobilized tephra - no eruption:

Description: From McGimsey and others (2004): "An AVO remote-sensing specialist on a commercial flight from Cold Bay to Anchorage on July 13, 1999 noted that the summit of Pavlof was snow-free and that the upper, snow-covered north flank appeared 'dirty'. A pilot reported on July 30 'ash to 5,000 feet [presumably above the summit] - no eruption'. Seismic and satellite data indicated no unusual activity. NWS personnel suggested that strong winds in the area were remobilizing ash deposits on the upper flanks and summit. Steam plumes from the summit were visible from Cold Bay on several occasions."
