Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Curacoa
A raft of floating pumice from a July 1973 submarine eruption behind the wake of a ship. This was the first report of an eruption from the Curacoa submarine volcano in the northern Tonga Islands. The pumice raft covered an area of more than 100 km2 and was encountered by a ship 200 km to the W nearly two weeks after the start of the eruption. Another eruption was observed in the same general area in 1979. Photo by the crew of the vessel "Port Nicholson," 1973 (courtesy of Tom Simkin, Smithsonian Institution).

A submarine volcano south of Curacoa Reef at the northern end of the Tofua volcanic arc was first observed in eruption in 1973. Explosive eruptions, which produced large rafts of dacitic pumice, covering an area of more than 100 km2, were observed from the island of Tafahi, 27 km SSW. The eruption site was located about 6.5 km SW of Curacoa Reef. Multiple submarine vents are apparently located in this area; a second eruption was reported in 1979 from a location 13 km N of Tafahi.
