Cagua Volcano is one of the active volcanoes of the Philippines. It has erupted twice in recorded history.


Cagua, one of the active volcanoes in the Philippines, is located in the province of Cagayan. Specifically, it lies in the Cagayan Valley region, of northern Luzon island. Located in the northernmost part of the Sierra Madre mountain range,[2] it lies in a region of active volcanism which probably originates from a fault between Babuyanes and Luzon.[3] 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.[3]


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[edit]

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.
