Mount Binuluan (also known as Ambalatungan) is a remote volcano in the Kalinga province of the Cordillera Administrative Region of the Philippines. The 2,329-metre-high (7,641 ft) mountain is part of the Cordillera Central mountain range on Luzon island, the largest island in the country. Binuluan exhibits active volcanism through numerous fumarole fields, solfataras and hot springs on its slope. There were reports of possible eruptions in 1952 and 1986 (or 1987), but they are unverified. – Source
The Ambalatungan group is a cluster of several volcanoes on northern Luzon Island, Philippines, comprising 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. – Source
