Taal is one of 16 volcanoes selected worldwide by IAVCEI (International Association of Volcanology and Chemistry of the Earth’s Interior) a part of the USGS (United States Geological Society) as a Decade Volcano, perhaps this has something to do with its nickname: "killer volcano."²⁹  The Decade Volcanoes are part of a United Nations program with the goal to better employ emergency plans to reduce the impact of natural disasters, like having your golf course be covered by ash, or something like that... Products associated with this study are updated maps showing areas of past and present hazard levels, information on deposits, and close in depth monitoring.  Taal was selected as a Decade Volcano because of it’s frequent and sudden activity, complicated and little understood volcanology, the dense population of Manila located only ~60km away and easy accessibility.¹¹ It was chosen over Pinatubo by PHIVOLCS (Philippine Institute of Volcanology and Seismology) because of seismic events in both 1992 and 1994 at Taal where evacuations took place at Volcano Island and Taal Lake¹²
