Mount Binuluan

Mount Binuluan (also known as Ambalatungan) is a remote volcano in the Kalinga province of the Cordillera Administrative Region of the Philippines.

There are a number of sites with strong steam emission, fumarolic activity, surface sulfur deposits, hot fresh water springs, hot sulfurous water springs, sulfur staining of riverine rocks, poisonous gas emissions, recent volcanic gas related deaths (>100 in last 20 years at Batong Buhay mines alone), heat destruction of vegetation, poisonous water, fumarole fields with new and shifting activity.

A possible phreatic or steam eruption was reported from Mount Binuluan in 1952, during which a sulfur-rich debris flow killed a dozen people.

In 2007 and 2008, some 90- and 100-year-old elders in Barangay Tulgao in Tinglayan said the loss of life in 1952 was caused by an eruption during a typhoon followed with the collapse of a natural earth bank below Sugo-oc fumarole field, high on the northern side of the Bunog River.

Because of these, there was a large migration out of the village with the Dananao people taking possession of a land along the Tubuk-to-Aurora Road in eastern Kalinga and resettling there.
