Home Reef Volcano, Tonga

The eruption in Tonga is most likely to be at Home Reef. The underwater volcano erupted in August 2006 and formed an island. The crew from a yacht viewed the eruption from a distance of two miles. They reported the island was one mile in diameter with four peaks and a central crater which emitted steam and occasional ash eruptions. Photographs show steam and phreatic eruptions. Observers at a nearby island resort on 9th-11th August reported continuous thunder rumbling to the south and a huge plume of smoke and cloud rising up into the sky.

Volcanic Eruption in Tonga

A volcanic eruption in Tonga has formed a new island between islands of Kao in the Ha'apai Group and Late in the Vava'u Group. The most likely location is Home Reef volcano. The captain of a fishing boat reported a new island near Home Reef, SW of Vava'u. It was described as "bigger than Fotuha'a", which is a nearby island of 134 people. There has been no official confirmation of the new island from either Tonga's Ministry of Lands or the Tonga Defence Service. The captain of another Maritime Projects fishing boat, had witnessed the actual emergence of the new island. Local fishermen sometimes see signs of volcanic activity west of Tonga. It is fairly common to see floating pumice after seismic activity. Fisherman report rumbling sounds occasionally when passing overundersea vents. The sounds are loud enough to wake up passengers.
