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; and one, Leonard Kniaseff, which was active 1,800 years ago (C14). </P> <P> There are 50 Philippines volcanoes listed by the royal Smithsonian Institution's Global Volcanism Program (GVP) at present, of which 20 are categorized as "historical" and 59 as "Holocene". 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 . </P>
