List of active volcanoes in the Philippines

From Wikipedia, the free encyclopedia For a list of Philippine mountains which include those classified as active volcanoes, see List of mountains in the Philippines. [show]Map all coordinates using OSM Map all coordinates using Google Map up to 200 coordinates using Bing Active volcanoes in the Philippines, as categorized by the Philippine Institute of Volcanology and Seismology (PHIVOLCS), include volcanoes in the country having erupted within historical times (within the last 600 years), with accounts of these eruptions documented by humans; or having erupted within the last 10,000 years (holocene) based on analyses of datable materials. However, there is no consensus among volcanologists on how to define an "active" volcano. As of 2012, PHIVOLCS lists 23 volcanoes as active in the Philippines, 21 of which have historical eruptions; one, Cabalian, which is strongly fumarolic volcano[further explanation needed]; and one, Leonard Kniaseff, which was active 1,800 years ago (C14).[1] There are 50 Philippines volcanoes listed by the royal Smithsonian Institution's Global Volcanism Program (GVP) at present,[2] of which 20 are categorized as "historical" and 59 as "Holocene".[2] The GVP lists volcanoes with historical, Holocene eruptions, or possibly older if strong signs of volcanism are still evident through thermal features like fumaroles, hot springs, mud pots, etc.[3] Mayon in Albay is the most active volcano in the Philippines Taal in Batangas Kanlaon in Negros island Bulusan in Sorsogon Smith in Calayan Hibok‑Hibok in Camiguin Pinatubo in Zambales Musuan in Bukidnon Contents [hide] List See also References External links List[edit] The list below showing 25 active volcanoes in the Philippines was based on the PHIVOLCS list with some included from the GVP. The number is not definite and depends on someone's definition of "active" or historical timeframe. Descriptions under Eruption were based on the GVP website. The frequency of Historical Eruptions excludes questionable or Uncertain accounts based on the two sources mentioned.
