Geography & Climate
Santo Tomas is located in Philippines, within the Luzon Volcanic Arc of the broader Western Pacific Volcanic Regions. Situated at 16.33° N, 120.55° E in the Northern Hemisphere, the volcano lies within a tropical climate zone. At 2,260 meters above sea level, Santo Tomas rises above the surrounding terrain into montane or subalpine conditions. The elevation creates distinct ecological zones along its flanks, from forested lower slopes to exposed rocky terrain near the summit. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
GVP Reference Summary
Santo Tomas is a stratovolcano with numerous volcanic vents and fissures (Philippines Commission of Volcanology, 1981). There was a report of an eruption or "displacement" in the region on 4 January 1641, described as an outburst of water accompanied by an earthquake. That is also the date of the major eruption of Parker volcano in southern Mindanao that impacted much of the Philippines. The Asin Hot Springs are about 12 km NNW of the summit, but their connection to the volcano is unknown.
