Home Reef

Stratovulcano · Tonga · 10 m (sottomarino)

A partially eroded pumice cone formed during an eruption that began on 7 August 2006 is seen from the N on 18 December. By the end of the year, wave erosion had destroyed the cone. Floating dacite pumice from this eruption traveled as far as Australia. 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.

Sintesi geologica

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, large amounts of floating pumice, and an ephemeral 500 x 1,500 m island, with cliffs 30-50 m high that enclosed a water-filled crater. In 2006 an island-forming eruption produced widespread dacitic pumice rafts that drifted as far as Australia. Another island was built during a September-October 2022 eruption.

Sintesi da Wikipedia

Home Reef è un'isola effimera prodotta da un vulcano sottomarino, la cui sommità è emersa ripetutamente dalla superficie del mare in seguito all'attività eruttiva. Le isole effimere hanno per definizione una durata limitata nel tempo, in quanto vengono erose in tempi brevi dal moto ondoso e dall'azione dei venti.
