Incandescent spatter accumulated on the summit and was moving down a deep gully on the northwest flank of the volcano. On the 27th, staff of the volcano observatory made airborne observations and reported low level fountaining and occasional small explosions of incandescent material in the summit crater. Satellite images showed thin ash plumes extending as far as 30 miles (45 km) from the volcano. Although visual and satellite observations were difficult due to bad weather volcanologists correlated the increased earthquake activity with eruptions that sent plumes as high as 4,000 feet (1,200 m) above the summit. On Tuesday the 24th, earthquake activity began to increase, indicating stronger eruptions relative to the previous week. The seismic stations continued to record earthquakes the following week that indicated a low level of activity. Bad weather hampered visual observations. The volcano is monitored by six seismic stations operated by the volcano observatory. Earthquakes indicated a low level eruption. Satellite images showed a hot spot near the cone. The volcano observatory was alerted to the eruption by residents near the volcano who saw an unusual plume. The eruption began on September 16, 1996. Volcanologists at the Alaska Volcano Observatory reported a small eruption at Pavlof volcano on the Alaska Peninsula. Geological Survey's Alaska Volcano Observatory on Volcan ListServ on June 3, 1997. This update is based on information posted by the U.S. Pavlof last erupted from September to December, 1996. The Alaska Volcano Observatory monitors the volcano and expects renewed activity. Two days later the National Weather Service in Cold Bay reported a steam plume rising 3,000 feet (1,000 m) above Pavlof's summit. An increase in earthquake activity was noted at Pavlof on June 1, 1997.
