Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Gaua
A steam plume rises from the historically active crater of Mount Garat in this view across Lake Letas, within the 6 x 9 km wide summit caldera of Gaua volcano (also known as Santa Maria). Construction of Mount Garat (Gharat) and other small cinder cones in the SW part of the caldera left this crescent-shaped caldera lake. The symmetrical, flat-topped Mount Garat cone is topped by three craters. The onset of eruptive activity from a vent high on the SE flank of Mount Garat in 1962 ended a long period of dormancy.
