The Ambalatungan group is a cluster of several volcanoes on northern Luzon Island, Philippines, conprising Ambalatungan, Bumabag, Podakan, and Binuluan volcanoes, aligned roughly E-W. Ambalatungan volcano is dacitic in composition, and has a steep-walled crater, inside which there are hot springs and strong fumarole vents which produce loud noises and have sulphur deposits. Bumabag volcano is located only 3 km east of Ambalatungan and has 2 craters that also produce strong fumarolic activity. Podakan volcano is 1 km SE of Bumabag and also has a large steam vent. A possible steam eruption might have occurred from Mount Binuluan in 1952, which killed 12 people by a sulfur-rich debris flow.
