A submarine volcano of the Tonga–Kermadec Ridge, informally called Volcano 2, is situated southwest of Tongatapu. It lies 68 m (223 ft) beneath the surface and could be the cone of a larger volcano located 15 km (9.3 mi) northwest. An eruption in 1907 located 48 km (30 mi) from Tongatapu created pumice rafts while the most recent eruption occurred in 1932.[1]
