Tondano is an approximately 20 x 30 km Quaternary caldera in north Sulawesi containing post-caldera pyroclastic cones, obsidian flows, and thermal areas. Lake Tondano lies against the well-defined eastern caldera rim. The historically active andesitic-to-basaltic stratovolcanoes Soputan, Sempu, Lokon-Empung and Mahawu (described elsewhere in this compilation) lie astride the poorly defined southern and northern rims of the caldera. The age of the latest eruptions within the caldera is not known, although thermal areas occur at Batu Kolok and Sarangson, and at the Tampusu cinder cone and Lahendong maar.
