is located in the province of Cagayan. Specifically, it lies in the Cagayan Valley region, of northern Luzon island. Part of the Cordillera del Kate, a sub-group of the Caraballo Mountains, it lies in a region of active volcanism which probably originates from a fault between Babuyanes and Luzon. Though there is a more evident seismic record between northeast Luzon and the islands, volcanoes occur on the northwestern side of the island. Evidence of a correlation between the two islands includes agglomerates from multiple volcanoes and pebbles of andesitic lava throughout the region.

| Mount Cagua, Cagayan Valley Regon, Northern Luzon, Philippines. Elevation : 1,133 m (3,717 ft) Type : Stratovolcano Ages of Rock : Pleistoscene Volcanic arc/belt : Babuyan (Bashi) Segment of Luzon-Taiwan Arc Last eruption : 1907 |
Activity of the early Pleistocene erupted basaltic andesite or effusive basalt. The volcano was covered by enormous lava flows from 600,000 to 300,000 years ago. It has seen activity ranging from phreatic eruptions to ash flows. The volcano is topped by a 1.5 kilometers (1 mi) wide crater marked by sharp and precipitous walls.
It has six hot springs. Maasok near the crater; Marafil in the northwest; Manaring, 5 kilometres (3.1 mi) north-northeast; San Jose, 10 km (6.2 mi) north-northeast; Kabinlangan, 3 km (1.9 mi) northwest and Paminta, 2 km (1.2 mi) north-northwest.
Eruptive activity
Two historical eruptions have taken place at the volcano. Activity in 1860 was largely phreatic though it was possibly followed by a pyroclastic flow. Renewed solfataric eruptions took place in 1907.
