    • Disaster hotspot: Philippines
      • Hydro-meteorological
        • Reasons for hydro-meteorological disasters
          • Country lies on inter-tropical convergence zone
          • It's northern and eastern coasts face the Pacific ocean
          • Affected by La Nina events
        • The Guinsaugon landslide, 2006
          • Killed 1150 people
          • Physical causes
            • Unseasonable torrential rain; 2000 mm in 10 days
            • La Nina - a cyclic ocean and wind current affecting SE Asia (probably the cause the rainfall)
          • Human causes
            • Deforestation of native forest cover protecting the soil

        • Economic loss: $710 million
    • Reasons for geophysical disasters
      • Tectonic plates
        • Destructive plate boundary
        • Dense philippine (oceanic) plate boundary subducts underneath the Eurasian (continental) plate bounadry partially melting the plate and creating magama
