EVENT SPECIFIC INFORMATION

Event Name : Makushin 2000/7

Start:July 2000 Observed
Stop:June 2001 Observed

Seismicity with no confirmed eruption: BibCard BibCard
Eruption Type:Not an eruption.

Description: From McGimsey and others (2004): "On February 22, 2001, pilot Joe Polanco reported smelling sulfur and seeing steam issuing from the summit area of Makushin as he flew by. Over the next several months, as tremor from the eruption of Cleveland volcano, 230 km (~145 mi) to the west was being recorded on the Makushin network, AVO seismologists began to suspect that some of the seismicity was actually being generated at Makushin. By May, 2001, it was determined that a real increase in seismic activity beneath Makushin had begun in July, 2000, and on June 1, 2001, AVO included Makushin in the Weekly Update. Earthquakes ranging in magnitude from 0 to 1.5 were occurring at a depth of between 0 and 8 km. AVO continued to closely monitor the activity, which became intermittent by mid-summer and slowly faded back down to background levels through the fall months."
