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]

Mount Pinatubo is an active stratovolcano in the Zambales Mountains, located on the tripoint boundary of the Philippine provinces of Zambales, Tarlac and Pampanga, all in Central Luzon on the northern island of Luzon. Its eruptive history was unknown to most before the pre-eruption volcanic activity of early 1991.

<span class="mw-page-title-main">Mount Arayat</span> Volcano in the Philippines

Mount Arayat is a potentially active stratovolcano sleeping in the province of Pampanga on the island of Luzon, Philippines, rising to a height of 1,033 metres (3,389 ft). The volcano has a breached crater on its northwest side with a smaller andesitic dome in the collapse amphitheater. There are no historical records of eruption in Arayat and the only dated rocks are 530- and 650-thousand-year-old basalts predating the collapse and formation of the lava dome. However, weak steaming is currently present in some of the heavily eroded vents on the North Western side of the summit. Additionally an analysis report indicates that the volcano erupted over the last 2,000 years, but it is believed to refer to the volcanic activity of the volcano. The Mount Arayat National Park was established in 1933.
