Geology
The Smithsonian Institution's Global Volcanism Program list Binuluan under Ambalatungan Group. The dacitic little-known cluster of volcanoes and the Philippine Commission of Volcanology (1981), and as Mount Binuluan by Wolfe (1982)] was described as consisting of three volcanoes constructed along a roughly E-W line. Binuluan volcano contains a steep-walled crater with hot springs and vigorous sulfur-encrusted fumarolic vents that produce loud noises. Bumabag volcano, 3 kilometres (1.9 mi) east of Binuluan, has two craters that also show strong fumarolic activity. Podakan volcano, 1 kilometre (0.62 mi) SE of Bumabag, also has a large steam vent. The Bumabag and Podakan volcanoes could possibly be flank vents of Mount Binuluan.
The Philippines Institute of Volcanology and Seismology (PHIVOLCS) lists Binuluan or Ambalatungan as an inactive volcano.
