The 40-km-wide volcanic Guaya Island contains Lake Letas within a 6 x 8 km caldera in the center of this September 2019 Planet Labs satellite image monthly mosaic (N is at the top). The active Mount Garet formed within the caldera and has two summit craters; explosive eruptive activity occurred from the SE crater in 2009-2010. Smaller cones and lava flows have formed across the flanks.
