Philippines is an archipelago comprising 7,107 islands, of which 1,000 are inhabitable. With a topography characterized by mountainous terrain bordered by narrow coastal plains, it is among the world’s most disaster-prone countries. Commonly occurring hazards include floods, droughts, typhoons, landslides and mudslides, earthquakes, and volcanic eruptions. Recent decades have witnessed an increase in damaging extreme events, such as heavy rainfall and tropical cyclone activity — a trend that is expected to continue under a changing climate.
