Details for: Ruang

Ruang volcano, seen here from the nearby island of Tagulandang, forms a small 4 x 5 km island that is part of a chain of islands extending north from Sulawesi. Explosive eruptions, recorded in historical time since 1808, have been accompanied by pyroclastic flows and lava dome formation, and have frequently caused damage to populated areas.
