CAGUA VOLCANO IN CAGAYAN


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, 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. - http://en.wikipedia.org/wiki/Cagua_Volcano

This volcano is 3,717 feet high with a distinct summit crater. An explosive eruption was recorded in 1860. Signs of activity were observed in 1907 but no eruptions took place and the volcano has been quiet since.  - http://wikimapia.org/1901450/Mt-Cagua-Volcano

Cagua volcano is located in northern Luzon, Philippines. It is considered part of the Babuya segment because it falls within the N-S trend of the active volcanoes and is east of the trend of the Northern Luzon extinct volcanic centers.
Mt. Cagua is a calcalkaline basaltic and andesitic stratovolcano, which has been built up by at least three eruptive phases:
1) An effusive phase between 1.5 and 1.2 Million years ago.
2) Emission of thick andesitic pyroclastic flows at approximately 670,000 years ago.
3) Young ash flow deposits, deposits, some of which were phreatomagmatic in origin.

MOUNT BINULUAN IN KALINGA PROVINCE




Source:  https://en.wikipedia.org/wiki/Mount_Binuluan


Mount Binuluan is a remote volcano in the Kalinga province of the Cordillera Administrative Region (CAR) Region of the Philippines. The 2,329-metre (7,641 ft) high mountain is part of the Cordillera Central mountain range on Luzon island, the largest island in the country. Binuluan exhibits active volcanism through numerous fumarole fields, solfataras and hot springs on its slope. There were reports of possible eruptions in 1952 and 1986 (or 1987), but they are unverified.

Mount Binuluan [Bin-oo-loo-ahn (Lubuaganyen dialect)] is one of the highest peaks in the area. The mountain is surrounded by the municipalities of Lubuagan, Pasil and Tinglayan in Kalinga province.

Southeast of the mountain is the Chico River flowing from southwest to northeast direction, while due northwest of the mountain is Pasil River, also flowing from southwest to northeast direction merging with Chico River just past the mountain. Mount Binuluan belongs to a range of mountains situated between the two rivers, trending southwest to northeast. Just southwest of Binuluan is Mount Mosimus 2,178 m (7,146 ft), followed by Mount Cauitan 2,569 m (8,428 ft) and Mount Alchan (Alchanon) 2,567 m (8,422 ft), the 19th and 20th tallest mountain in the Philippines. South of this line of mountains are Mount Chumangil 1,996 m (6,549 ft) and Mount Patoc 1,819 m (5,968 ft), the other volcano of the Central Cordillera Range displaying strong fumarolic activity.



Mount Binuluan is usually covered in cloud or mist and so photographs could be difficult to obtain. The village of Bangtitan in Upper Uma in Lubuagan is a good vantage point for views and photography of the mountain on the rare occasions when the primary peak is not mist-enshrouded. It is not known if Binuluan itself has ever been climbed as access to the site is very difficult. The terrain is rugged and undeveloped.

Mount Binuluan exhibits a number of active geothermal features. There are a number of sites with strong steam emission, fumarolic activity, surface sulfur deposits, hot fresh water springs, hot sulfurous water springs, sulfur staining of riverine rocks, poisonous gas emissions, recent volcanic gas related deaths (>100 in last 20 years at Batong Buhay mines alone), heat destruction of vegetation, poisonous water, fumarole fields with new and shifting activity. - Wikipedia.org

MOUNT BILIRAN IN SAMAR


Photo from:  biliranisland.com

The volcanic island of Biliran, located across the narrow Biliran Strait from the northern tip of Leyte Island, contains many prominent andesitic lava domes, the highest of which is 1301 m Surio. Several Pleistocene K-Ar dates have been obtained from volcanic centers on northern Biliran Island. Fumarole fields are scattered throughout the 20 x 35 km wide island. The only known historical activity at Biliran was a phreatic explosive eruption and possible debris avalanche at a thermal area in 1939. - silent-gardens.com

Mount Biliran is an active volcano in the Philippines. It is a complex (compound) volcano, meaning that it has more than one feature. These volcanoes form because of changes of their eruptive characteristics or the location of multiple vents in an area. - wiki.answers.com

Biliran is a compound volcano that makes a large mountainous island just north of the island of Leyte.  Biliran's single historic eruption was from a flank vent in 1939. There are five solfatara fields on the island. The solfatara on the west side of Mt. Guinon contained more than 400 tones of sulfur in 1880. - volcano.oregonstate.edu
