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.
