The Alert Level for Gaua volcano remains at Level 1.
This means that the volcanic activity remains unrest. The area of risk is around the volcanic crater.
This is a reminder to all visitors do not approach the volcanic crater to avoid volcanic gases impact and any other volcano activity impacts.
All communities, villages, visitors and travel agencies have to seriously consider this information.
The Vanuatu Meteorology and Geo-Hazards Department will continue to closely monitor this volcano activity. More information will be provided when necessary.
The roughly 20-km-diameter Gaua Island, also known as Santa Maria, consists of a basaltic-to-andesitic stratovolcano with an 6 x 9 km wide summit caldera. Small parasitic vents near the caldera rim fed Pleistocene lava flows that reached the coast on several sides of the island; several littoral cones were formed where these lava flows reached the sea. Quiet collapse that formed the roughly 700-m-deep caldera was followed by extensive ash eruptions. Construction of the historically active cone of Mount Garat (Gharat) and other small cinder cones in the SW part of the caldera has left a crescent-shaped caldera lake. The symmetrical, flat-topped Mount Garat cone is topped by three pit craters. The onset of eruptive activity from a vent high on the SE flank in 1962 ended a long period of dormancy.
