This September 1995 photo shows a Surtseyan plume at Ruapehu during the eruption through Te Wai ā-Moe (Crater Lake), forming the dark cock’s-tail plume above the vent and a gas-and-steam plume to the left from the lake water. Two lahar paths descend the Whakapapa ski field on the northern flank in the foreground. A third lahar traveled down the eastern flank Whangaehu Valley.
