Crater Peak erupted for the final time in 1992 during the night of September 16-17. Like the first two eruptions, this event was brief and explosive, sending a tephra cloud to 15 km in altitude over the volcano. Hot debris cascaded onto the surface of the Kidazgeni Glacier, adjacent Crater Peak, causing extensive melting and scouring of the ice, shown here. Down slope, these avalanches of hot debris became increasingly water-rich and formed lahars which rushed down a steep-walled canyon and temporarily dammed the Chakachatna River. The tephra cloud from this eruption traveled ENE just missing Anchorage but heavily impacted the communities in the Matanuska-Susitna and Cooper River basins. Image Credit: C.A. Gardner. U.S. Geological Survey Photo Date: September 23, 1992 June 27, 1992 Mount Spurr USA volcano Following 39 years of inactivity, Crater Peak vent on the south flank of Mount Spurr volcano burst into eruption at 7:04 a.m. Alaska daylight time (ADT) on June 27, 1992. The Municipality of Anchorage reported nearly $2 million in damage, office closures, and cleanup costs from the August eruption. In addition, there were numerous, small-scale losses incurred by businesses. No loss of life resulted directly from the eruptions. However, two heart attacks, one fatal, from shoveling ashfall were reported in Anchorage. Event Data:
