A plume rises above Fourpeaked during its first observed eruption, on 7 September 2006, as seen from Main Street in Homer, across Cook Inlet. The plume rose to a maximum height of 6 km and resulted in a trace of ashfall at Nonvianuk Lake outlet (110 km WNW) and near Homer (150 km NE). The eruption produced a 1-km-long fissure that extended north from the summit.
