Successive pyroclastic avalanches formed overlapping, lobate tongues of coarse debris that coursed down the upper flanks of Crater Peak and funneled into pre-existing drainage. The farthest traveled pyroclastic flows moved about 3 km from the crater rim, descending more than 1000 m, as shown in this oblique view of the south flank of Crater Peak. Image Credit: C.A. Neal. U.S. Geological Survey Photo Date: September 3, 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:
