    • Typhoons
      • Typhoon Bopha (2012)
        • Destroyed 90% of three coastal towns in Davao Oriental province

          • Reduction of shallow rooted trees (such as coconuts) which prevented silitation.
        • PHYSICAL factors

          • 2.6 magnitude earthquake had hit

    • Questions
      • Explain how physical factors have lead to a range of hazard risk in the Philippines (15) June 2012
      • Explain why volcanic hazards are common in the Philippines but not on the Californian coast (5)June 2011
      • Explain how physical and human factors have made the Philippines a disaster hotspot (5) June 2010
      • Explain how tropical cyclones contribute to the risk of living in the Philippines; a disaster hotspot (4) January 2010

        • Second eruption caused the side of the volcano to collapse creating a pyroclastic blast and huge lahars
          • Two week before the blast, the government produced a video showing the risks of pyroclastic flows and lahars
        • Economic loss was $710 billion-mainly agricultural and property
