The Philippines' exposure to disasters is to a significant extent due to the country's geographical and physical characteristics (CDRC, 1992). It is the world’s largest archipelago composed of more than 7,100 islands. It lies along the Western Pacific Basin, the world’s busiest typhoon belt, with the average of 20 typhoons hitting the country each year. Coastal and extended swamp areas are prone to floods and storm surges during typhoons. The country is further part of the Circum-Pacific seismic belt and lies in between two major tectonic plates, whose movements create mountain ranges, islands, volcanoes, earthquakes and tsunamis. There are 220 volcanoes in the country, out of which 21 are active. El Niño occurrences induce drought in many parts of the Philippines, regularly posing a serious problem in agricultural production and potable water supply.
