Negros Island
Negros is the fourth largest and third most populous island in the Philippines, with a total land area of . Negros is one of the many islands of the Visayas, in the central part of the country. The predominant inhabitants of the island region are mainly called ''Negrenses'' (locally ''Negrosanons''). As of 2020 census, the total population of Negros is 4,656,945 people. From May 29, 2015 to August 9, 2017, the whole island was governed as an administrative region officially named the Negros Island Region, which comprised the highly urbanized city of Bacolod and the provinces of Negros Occidental and Negros Oriental, along with its corresponding outlying islands and islets within a total regional area of . It was created on May 29, 2015 by virtue of ''Executive Order No. 183'' issued by Benigno Aquino III, who was the president at that time. On August 9, 2017, President Rodrigo Duterte signed the Executive Order No. 38 dissolving the Negros Island Region. History Precolonial ...

Visayas
The Visayas ( ), or the Visayan Islands (Visayan: ''Kabisay-an'', ; tl, Kabisayaan ), are one of the three principal geographical divisions of the Philippines, along with Luzon and Mindanao. Located in the central part of the archipelago, it consists of several islands, primarily surrounding the Visayan Sea, although the Visayas are also considered the northeast extremity of the entire Sulu Sea. Its inhabitants are predominantly the Visayan peoples. The major islands of the Visayas are Panay, Negros, Cebu, Bohol, Leyte and Samar. The region may also include the provinces of Palawan, Romblon, and Masbate whose populations identify as Visayan and whose languages are more closely related to other Visayan languages than to the major languages of Luzon. There are three administrative regions in the Visayas: Western Visayas (pop. 7.9 million), Central Visayas (8 million) and Eastern Visayas (4.5 million). The Negros Island Region existed from 2015 to 2017, separating N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stratovolcano
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 volcano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Potentially Active Volcano
A volcano is a rupture 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 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 volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide p ...

Northern Negros Natural Park
The Northern Negros Natural Park is a protected area of the Philippines located in the northern mountainous forest region of the island of Negros in the Visayas. It is spread over five municipalities and six cities in the province of Negros Occidental and is the province's largest watershed and water source for seventeen municipalities and cities including the Bacolod metropolitan area. The park was established first as a forest reserve spanning on 28 April 1935 through Administrative Act No. 789 signed by Governor-General Frank Murphy. On 7 August 1946, the Northern Negros Forest Reserve was reduced to its present area of with the signing of Proclamation No. 798 by President Manuel Roxas. In 2005, the protected area was converted into a natural park under the National Integrated Protected Areas System (NIPAS) Act by virtue of Proclamation No. 895 signed by President Gloria Arroyo.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Active Volcanoes In The Philippines
