The volcano quieted down after the June 27 eruption, and it appeared as if, similar to the 1953 eruption, this phase of activity had ended. However, on August 18, 1992, a pilot reported ash over the volcano. At 1641 AST, without significant seismic precursors, Crater Peak again erupted, suddenly and explosively, sending pulverized rock to more than 14 km altitude. Winds blowing east over the volcano carried the tephra plume over upper Cook Inlet and the City of Anchorage. AVO observers on board a small aircraft documented the violent eruption column roiling over the vent. In this view, steam-condensate rises around the base of the column where hot debris has fallen on snow and ice. Image Credit: R.G. McGimsey. U.S. Geological Survey Photo Date: August 18, 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:
