A lighter toned ash cloud rising off the south flank of Crater Peak resulted from avalanches of hot debris, or pyroclastic flows, that had traveled down the side of the cone towards the Chakachatna River. The summit of Mt. Spurr is at left. The spreading eruption cloud at this time has reached at least 14 km altitude and formed a wide, anvil-shaped cloud. 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:
