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.

IRIGA VOLCANO IN CAMARINES SUR

Mount Iriga volcano is a small stratovolcano immediately SW of Lake Buhi in southern Luzon, Philippines.

The volcano is dominantly andesitic in composition, but has several basaltic flank cones. It has a large crater breached to the SE, which formed during a massive flank failure that produced a large debris avalanche which buried several villages and formed a hilly, irregular deposit on the plain south of Lake Buhi 4 km from the summit.

Background:

Iriga is part of the Bicol volcanic arc which comprises at least 12 volcanic vents and complexes and is one of the 3 historically active, but the least active centers of the arc (the other 2 being Mayon and Bulusan). Iriga has only 2 known recorded eruptions in historic times.

The catastrophic debris avalanche of Iriga volcano had been believed to have occurred during the 1628 AD eruption, but later work has now shown that the collapse and eruption occurred earlier at some unknown date in the past few thousands years. The avalanche was followed by phreatic explosions that created a small crater at the base of the scarp.

Mount Iriga, also known as Mount Asog, is one of the active volcanos in the Philippines, in the province of Camarines Sur, in the Philippines.

Mount Iriga is a stratovolcano about a kilometre from Lake Buhi. It rises 1,196 m (3,924 ft) with a base diameter of 10 kilometres.

Iriga erupted in 1628 and 1642. Iriga is generally known for its phreatic explosions.

Iriga volcano is located in southern Luzon, Philippines. The Bicol Arc is composed of at least twelve volcanic centers and complexes that include three active volcanoes (Mayon, Iriga and Bulusan). Iriga is the least active of the three active volcanoes having had only two eruptions recorded throughout its history.

The southern flank of Iriga has collapsed previously, causing a debris avalanche which traveled several kilometres, damming a river and creating a lake.

A left-lateral strike-slip fault passes under Iriga volcano.

Crater lake Buhi is located 4 km east of the summit. The lake is the home to the world's smallest edible commercial fish - Sinarapan (Mistichthys luzonensis).

The hazards at Iriga volcano are lava flows, pyroclastic flows, airfall tephra, debris avalanche and lahars.

MT. DIDICAS IN CAGAYAN

Didicas volcano is a small volcanic island 22 km NE of Camiguin Island, 60 km off the northern coast of Luzon, Philippines.

Photo from:  http://flickr.com



Until 1952, it was a submarine volcano that had previously formed temporary islands during eruptions. In the eruption of 1952 the submarine volcano formed a new lava dome that surfaced above sea level and has become now a permanent new island.

 

Background:

Didicas volcano now consists of a small, 244-m-high andesitic lava dome about 1.4 km in its longest diameter.

A 400-m-wide crater was formed during the 1952 eruption. The first recorded submarine eruption of Didicas occurred in 1773.

In an eruption in 1860, Didicas also built a new island, the first recorded cone of Didicas breaching the sea surface. It reached a height of 213 m in 1860, when the eruption ended, but it was soon eroded beneath the sea, because it mainly consisted of loose tephra. 3 rock masses up to 82 m high were left after an eruption in 1900. 2 more eruptions occurred since 1952 at an explosion crater on the northern side of the island.

Mt. Malinao is the second of the 'Magayon Trio' - the three beautiful mountains of the province of Albay. Of course, the first and by far the most famous is no less than the famous Mayon, where the very concept of Bicolano beauty derives. Malinao, as its name in various Filipino languages denote, means 'clear' and likely it is the clarity of the mountain's waters that is described in the appellation. A striking example is Vera Falls, at the slopes of Mt. Malinao, itself a beautiful destination.

A lush forest surrounds Mt. Malinao, but prior to this, abaca plantations are encountered, a sight very typical of the hinterlands of Bicol. The forest is quite dense, reminiscent of Mt. Isarog. Although there are several peaks on the caldera rim of Mt. Malinao (being an old volcano), the usual trek only goes to the first peak, because of security concerns.

MT. MAKILING IN LAGUNA

The mystical Mount Makiling is the home of over a thousand diverse species of flora and fauna. Just a two-hour drive from Manila, this legendary mountain towering over Los Baños, Laguna and Sto Tomas, Batangas offers an ideal respite to commune with nature, experience the vanishing rainforest, and embark on a multitude of different adventures. It offers varied activities including simple nature tripping at the Botanical Garden and Pook ni Mariang Makiling, bird and butterfly watching, camping and trekking on its network of trails, swimming in its numerous hot springs, and mountain biking. This inactive volcano rises 1109 meters above sea level and offers a glimpse of some geological wonders like the Mud Spring – a sulfuric vent just 692m trek off the main trail, and the Flat Rocks – where you can swim in refreshing mini-sized water falls or just enjoy the lush greenery.

Mt. Makiling is a popular hiking destination. The two major trails begin at the UPLB College of Forestry and Brgy. San Miguel, Sto. Tomas, Batangas. The UPLB trail is more commonly used, taking 4–5 hours to reach the summit (Peak 2). However, this trail is closed as of October 2007 due to trail damage wrought by Typhoon Xangsane on September 2006. The other trail from Sto. Tomas passes by other peaks, is more difficult, and requires 6–7 hours to reach the summit. Both trails are generally established and safe, although throughout the years there have been occasional reports of fatal accidents and injuries, especially on the Sto. Tomas side. Climbers also frequently encounter leeches along the way.
