Inactive volcanoes in the Philippines include Mount Balatubat in the Luzon Straight, Mount Banahao de Lucban in Luzon, Imoc Hill in the Laguna Volcanic Field, Lake Muhikap in Laguna Maars, Mount Catmon in Visayas, Mount Bacauan in Sulu, Mount Urot in the Tukuran Volcanic Field, Mount Baya in Mindanao and Mount Kitanglad in Bolacanon Volcanic Field. As of 2014, the Philippine Institute of Volcanology and Seismology lists 355 inactive volcanoes.Know More
The inactive volcano Mount Kitanglad is one of the tallest peaks in the Philippines and forms part of the Kitanglad Mountain Range. Many of the inactive volcanoes are currently lakes, with water filling their craters. The tallest mountain in the Laguna Volcanic Field is Mount Makiling, and its previous eruption date is not known. The field contains 200 dormant volcanoes. Although inactive, the underground heat from the volcanoes causes hot springs and areas of geothermal mud.
The Institute defines an inactive volcano as a volcano with a record of previous eruption that is not expected to erupt again in the near future. However, an inactive volcano does contain the necessary plumbing for a potential eruption. Inactive volcanoes may also be referred to as dormant. Volcanoes may also be classified as active or extinct.Learn more about Volcanoes
No two volcanoes are exactly the same, as they all have differences in dimensions of their mountains and craters, as well as their relative frequency and type of eruption. Volcanoes come in cinder cone, shield and stratovolcano varieties.Full Answer >
Volcanic vents allow the Earth to release built up gases from the heat and pressure emanating from its core. Magma rises towards the surface, and as the pressure builds the magma seeks outlets through which to flow. The higher the pressure build-up, the greater the volcanic explosion.Full Answer >
The largest waterfall in the Philippines is located on the island of Mindanao and is called Aliwagwag Falls. It is 1,110 feet from the top of the falls to the Canteel River and measures 65 feet across the falls.Full Answer >
The primary impact volcanoes have on the environment is the release of volcanic gases into the atmosphere. Volcanoes release around 130 million tons of carbon dioxide each year, as well as toxic pollutants like sulfur dioxide, hydrogen sulfide, hydrogen chloride and hydrogen fluoride. However, volcanoes can also have a positive impact on the environment because the lava and ash produced by an eruption contain valuable nutrients for the soil.Full Answer >
