An overflight on June 26 revealed that the lake in Crater Peak had disappeared. After four hours of energetic seismicity, Crater Peak erupted explosively at 0704 AST on June 27, 1992. The eruption occurred under heavy cloud cover and was not photographed. Tephra from the 15-km high eruption column darkened the snow and ice of the surrounding mountains. Ashfall was reported as far away as Manley Hot Springs, 425 km north of the volcano. In this view, looking NNW towards Crater Peak, the tephra-mantled summit of Spurr is visible behind Crater Peak and to the right. A steam-condensate plume rises from the Crater Peak vent. During the eruption, avalanches of hot debris flowed down the south flank of Crater Peak and mixed with snow to form debris flows, or lahars, which reached the Chakachatna River, not visible in this view.

U.S. Geological Survey Photo Date: July 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:
