Geography

Cagua is one of the active volcanoes in the Philippines located in the province of Cagayan in the Cagayan Valley Region of northern Luzon in the northernmost part of the Sierra Madre mountain range.[2] The mountain is approximately 12 kilometres (7.5 mi) south of Gonzaga, Cagayan and 14 kilometres (8.7 mi) south of Port Irene in Santa Ana, Cagayan.[3]

Geology

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-kilometer (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.[3]

Eruptive activity

Two historical eruptions have taken place at the volcano. Activity in 1860 was a largely phreatic eruption though it was possibly followed by a pyroclastic flow. Renewed eruptions took place in October 1907 .[3]

[it] Monte Cagua

Il Cagua, anche Kawa, Caua e Gagua, è uno stratovulcano attivo delle Filippine[1] alto 1 160 m.s.l.m. che sorge nella Provincia di Cagayan, nell'estremo nord dell'arcipelago asiatico. Il Cagua è un complesso costituito di basalto e andesite con un diametro alla base di circa 12 km e un cratere largo 1,5 km: nei pressi del cratere sono presenti le fonti termali di Kabinlanganì, Maasok, Magrafil, Manaring e Paminta. [2]. L'attività vulcanica storica del Cagua riporta di una eruzione stromboliana nel 1860 e di una forte fase solfatarica nel 1906.
