Mountains Of The Philippines
The following is an incomplete list of mountains in the Philippines. Several of these are volcanoes, formed by subducting tectonic plates surrounding the archipelago. List This list contains most of the highest mountains in the country. It is limited to mountain 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''. ''(note: to minimize clutter, citations for names are limited only to mountains with variant names, spellings, and/or those that currently do not have elevation data)'' * ''Elevation'': sorted in meters above sea level ''(note: Some mountains may contai ...

Volcanoes Of The Luzon Strait
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes 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 resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is stretching an ...

Stratovolcanoes Of The Philippines
A stratovolcano, also known as a composite volcano, is a typically conical volcano built up by many alternating layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and explosive eruptions. Some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and solidifies 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 can travel as far as 8 km (5 mi). The term ''composite volcano'' is used because strata are usually mixed and uneven instead of neat layers. They are among the most common types of volcanoes; more than 700 stratovolcanoes have erupted lava during the Holocene Epoch (the last 11,700 years), and many older, now ...

List Of Volcanoes In The Philippines
The Philippines, officially the Republic of the Philippines, is an archipelagic country in Southeast Asia. Located in the western Pacific Ocean, it consists of 7,641 islands, with a total area of roughly 300,000 square kilometers, which are broadly categorized in three main geographical divisions from north to south: Luzon, Visayas, and Mindanao. With a population of over 110 million, it is the world's twelfth-most-populous country. The Philippines is bounded by the South China Sea to the west, the Philippine Sea to the east, and the Celebes Sea to the south. It shares maritime borders with Taiwan to the north, Japan to the northeast, Palau to the east and southeast, Indonesia to the south, Malaysia to the southwest, Vietnam to the west, and China to the northwest. It has diverse ethnicities and a rich culture. Manila is the country's capital, and its most populated city is Quezon City. Both are within Metro Manila.

Volcanic Earthquake
A volcano tectonic earthquake or volcano earthquake is caused by the movement of magma beneath the surface of the Earth. The movement results in pressure changes where the rock around the magma has a change in stress. At some point, this stress can cause the rock to break or move. This seismic activity is used by scientists to monitor volcanoes. The earthquakes may also be related to dike intrusion and/or occur as earthquake swarms. Usually they are characterised by high seismic frequency and lack the pattern of a main shock followed by a decaying aftershock distribution of fault related tectonic earthquakes. Cause of volcano tectonic earthquakes One possible scenario resulting in a possible volcano tectonic earthquake occurs in tectonic subduction zones. The compression of plates at these subduction zones forces the magma beneath them to move. Magma can not move through the newly compressed crust as easily. This means it tends to pool in magma chambers beneath the surface and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philippine Institute Of Volcanology And Seismology
The Philippine Institute of Volcanology and Seismology (PHIVOLCS, ; ) 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 and terrestrial magnetic services of the Manila Observat ...

Volcanologist
A volcanologist, or volcano scientist, is a geologist who focuses on understanding the formation and eruptive activity of volcanoes. Volcanologists frequently visit volcanoes, sometimes active ones, to observe and monitor volcanic eruptions, collect eruptive products including tephra (such as Volcanic ash, ash or pumice), Rock (geology), rock and lava samples. One major focus of inquiry in recent times is the prediction of eruptions to alleviate the impact on surrounding populations and monitor natural hazards associated with volcanic activity. Geologists who research volcanic materials that make up the solid Earth are referred to as igneous petrologists. Etymology The word ''volcanologist'' (or ''vulcanologist'') is derived from the English volcanology (volcano + wikt:-logy, -logy), which was derived from the French wikt:volcanologie#French, volcanologie (or vulcanologie), which was further derived from the French word wikt:volcan#French, volcan (volcano), which was even furt ...
