Mount Tondano

Mount Tondano in the province of North Sulawesi, Sulawesi, Indonesia, has a 20 × 30 km wide caldera which was formed in the Late Miocene or Early Pliocene[2] by a massive eruption. Post caldera activity includes pyroclastic cones, obsidian flows and geothermal areas in the caldera area. Lake Tondano lies in the east side of the caldera.[1]

The 5 km long and 3.5 km wide ellipsoidal Pangolombian caldera lies entirely within the Tondano Caldera, and formed from a large eruption of an older Somma volcano.[2]

In more recent times, the somma volcanoes of Soputan, Sempu, Lokon-Empung and Mahawu have been constructed along the rim of the Tondano caldera, with Soputan being the youngest and most frequently active of the group.[1] The Tondano caldera has been investigated as a potential source for geothermal energy to support the growing population in the vicinity of the caldera.[2] Energy demand has been growing in Indonesia, and the Tondano caldera system could potentially provide clean energy for thousands of residents in northern Sulawesi.[2]
