The Philippines is located in what we call a 'disaster hotspot'. This means that it faces the threat of multiple hazards (several geophysical and hydro-meteorological hazards), and it is also very vulnerable to a hazard becoming a disaster. This documentary clearly outlines two things - why the typhoon was so extraordinary (the physical and climate geography of the event) and why it had such a huge impact in the Philippines.
