A seismometer had been installed on the rim of Crater Peak, in August of 1991. Signals from this instruments allowed AVO to track the build up of seismicity prior to the eruption. Several hours into the eruption, the seismometer stopped transmitting. This twisted steel pipe with 1/4 inch thick walls and a melted, blasted piece of corrugated, galvanized steel was all that remained of the geophone, batteries, culvert, and antenna.

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:
