Mountains Of The Philippines
The following is a partial list of mountains in the Philippines. Several of these are List of volcanoes in the Philippines, volcanoes, formed by subduction, subducting tectonic plates surrounding the archipelago. List This list contains most of the highest mountains in the country. It is limited to mountain Summit (topography), peaks with, if known, an elevation of at least above sea level, and may include those considered as hills. The distinction between a hill and a mountain in terms of elevation is unclear and largely subjective, but a hill is universally considered to be less tall and less steep than a mountain. * ''Name'': mountains are sorted according to ''only name''s (without the "Mount" prefix) for easier reference in name and spelling variants. Unnamed peaks are ''italicized''.

Cordillera Administrative Region
The Cordillera Administrative Region (CAR; ilo, Rehion/Deppaar Administratibo ti Kordiliera; fil, Rehiyong Pampangasiwaan ng Cordillera), also known as the Cordillera Region and Cordillera (), is an administrative region in the Philippines, situated within the island of Luzon. It is the only landlocked region in the insular country, bordered by the Ilocos Region to the west and southwest, and by the Cagayan Valley Region to the north, east, and southeast. It is the least populous region in the Philippines, with a population less than that of the city of Manila. The region comprises six provinces: Abra, Apayao, Benguet, Ifugao, Kalinga and Mountain Province. The regional center is the highly urbanized city of Baguio. The region was officially created on July 15, 1987, and covers most of the Cordillera Central (Luzon), Cordillera Mountain Range of Luzon and is home to numerous ethnic peoples.

Philippine Institute Of Volcanology And Seismology
The Philippine Institute of Volcanology and Seismology (PHIVOLCS, ; tl, Surian ng Pilipinas sa Bulkanolohiya at Sismolohiya) is a Philippine national institution dedicated to provide information on the activities of volcanoes, earthquakes, and tsunamis, as well as other specialized information and services primarily for the protection of life and property and in support of economic, productivity, and sustainable development. It is one of the service agencies of the Department of Science and Technology. PHIVOLCS monitors volcano, earthquake, and tsunami activity, and issues warnings as necessary. It is mandated to mitigate disasters that may arise from such volcanic eruptions, earthquakes, tsunamis, and other related geotectonic phenomena. History This government organization was formed after a historical merging of official functions of government institutions. One of its first predecessors is the Philippine Weather Bureau created in 1901 when meteorological, seismological a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanoes Of Luzon
A volcano is a rupture in the Crust (geology), crust of a Planet#Planetary-mass objects, planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and volcanic gas, gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where list of tectonic plates, tectonic plates are divergent boundary, diverging or convergent boundary, converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot ...

Subduction Volcanoes
Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex. The process of subduction has created most of the Earth's continental crust. Rates of subduction are typically measured in centimeters per year, with the average rate of convergence being approximately two to eight centimeters per year along most plate boundaries. Subduction is possible because the cold oceanic lithosphere is slightly denser than the underlying asthenosphere, the hot, ductile layer in the upper mantle underlying the cold, rigid lithosphere. Once initiated, stable subduction is driven mostly by the negative buoyancy of the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stratovolcanoes Of The Philippines
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volcan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ring Of Fire
The Ring of Fire (also known as the Pacific Ring of Fire, the Rim of Fire, the Girdle of Fire or the Circum-Pacific belt) is a region around much of the rim of the Pacific Ocean where many Types of volcanic eruptions, volcanic eruptions and earthquakes occur. The Ring of Fire is a Horseshoe, horseshoe-shaped belt about long and up to about wide. The Ring of Fire includes the Pacific coasts of South America, North America and Kamchatka, and some islands in the western Pacific Ocean. Although there is consensus among geologists about almost all areas which are included in the Ring of Fire, they disagree about the inclusion or exclusion of a few areas, for example, the Antarctic Peninsula and western Indonesia. The Ring of Fire is a direct result of plate tectonics: specifically the movement, collision and destruction of lithosphere, lithospheric plates (e.g. the Pacific Plate) under and around the Pacific Ocean. The collisions have created a nearly continuous series of subdu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
