Kuwae

Caldera · Vanuatu · 2 m (submarino)

The forested cliff marks the upper caldera wall of the largely-submarine Kuwae caldera between Epi and Tongoa islands. The 6 x 12 km caldera contains two basins that cut the NW end of Tongoa Island and the flank of the late-Pleistocene or Holocene Tavani Ruru volcano on the SE tip of Epi Island. The Karua volcano lies near the northern rim of the caldera. It has formed several ephemeral islands since it was first observed in eruption during 1897.

Resumen geológico

The largely submarine Kuwae caldera occupies the area between Epi and Tongoa islands. The 6 x 12 km caldera contains two basins that cut the NW end of Tongoa Island and the flank of the Tavani Ruru volcano on the SE peninsula of Epi Island. Native legends and radiocarbon dates from pyroclastic-flow deposits have been correlated with a 1452 CE ice-core peak thought to be associated with collapse of Kuwae caldera; however, others considered the deposits to be of smaller-scale eruptions and the ice-core peak to be associated with another unknown major South Pacific eruption. The submarine Karua cone in the east-central part of the caldera has formed several ephemeral islands since it was first observed in eruption during 1897.
