Description: From McGimsey and Wallace (1999): "On Thursday, February 19, 1997, AVO received multiple pilot reports (PIREPs) of ash and steam rising to 5,000 ft (~1,500 m) above either Martin or Mageik volcanoes. No anomalous seismic activity was recorded on the Katmai seismic network, and no indication of eruptive activity was detected on satellite imagery.

"* * * Another observation of unusual steaming at Martin and Mageik was reported to AVO on December 11, 1997, via the Alaska Tsunami Warning Center, who received the report from a resident of Karluk Village on Kodiak Island. Using a spotting scope, the village resident had observed the peaks for the previous three weeks - noting no unusual activity - when on the morning of the 11th he witnessed a sudden increase in steam activity and watched as white, towering steam clouds billowed from Martin, subsided, and then rose again to about 600-700 ft (~200 m) above the vent, forming a large mushroomed top before dissipating. A second white, billowing steam plume then rose from adjacent Mageik. Local pilots also noticed the unusually vigorous activity." This steaming does not constitute a volcanic eruption.
