Following the August eruption, the inside of Crater Peak was mantled with pyroclastic debris and coarse talus from rock avalanches from the steep crater walls. The actual orifice or vent for the eruptions is located at the back (NW) corner of the crater, here steaming profusely. Other "rootless" fumaroles emit steam through the thick blanket of debris on the crater rim and where banked against the crater walls. Image Credit: T.P. Miller. U.S. Geological Survey Photo Date: August 20, 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:
