Observers from a Royal New Zealand Airforce aircraft reported venting and a sulphur smell from Home Reef on 8 December. The island was about 450 m in diameter, circular in shape, and rose to a height of 73 m (240 ft) a.s.l. The water around the island was cloudy with sediment.

Geologic Background. Home Reef, a submarine volcano midway between Metis Shoal and Late Island in the central Tonga islands, was first reported active in the mid-19th century, when an ephemeral island formed. An eruption in 1984 produced a 12-km-high eruption plume, copious amounts of floating pumice, and an ephemeral island 500 x 1500 m wide, with cliffs 30-50 m high that enclosed a water-filled crater. Another island-forming eruption in 2006 produced widespread dacitic pumice rafts that reached as far as Australia.
