Lake Hargy (lower right) lies in the SE corner of the 10 x 12 km wide Hargy caldera. The Lobu River drains the lake through a notch in the northern caldera rim. The post-caldera cone of Galloseulo lies beneath the large cloud bank in the center of the image, about half way from the lake to the Bismarck Sea. The Toiru River cuts across the bottom of the image. Small eruptions have taken place at Galloseulo over the past 7000 years, the last occurring about 1000 years ago.
