Gaua volcano is one of the active volcano in Vanuatu.
Construction of the historically active cone of Mount Garet and other small cinder cones in the SW part of the caldera has left a crescent-shaped caldera lake, Lake Letas.
The symmetrical, flat-topped Mount Garet cone is topped by three active craters.
Advice to all tourism agencies, local authorities, people of Gaua and the general public not to access the Gaua volcanic cone.
In this area volcanic gases will always be expected and other volcano risks could occur at any time in such major unrest state.
