  • Hazard Hotspots
    • The Philippines
      • Almost 100 million people
        • Population density of 797.2/sq mi
      • Destructive plate boundary
        • Geophysical Hazards
          • High magnitude earthquakes
            • As plate is subducted, two plates grind against each other causing pressure to build and when the release it triggers an earthquake
            • Luzon Island earthquake
              • 16th July 1990
              • 7.8 magnitude
              • 1666 people killed
                • 3000 people injured
              • $2.3 billion worth of damage
          • Powerful volcanoes
            • Mount Pinatubo eruption
              • 15th June 1991
              • 2nd largest eruption of 20th century
              • 847 people killed
              • 2.1 million people affected by the earthquake
                • Loss of homes, livelihoods or family
              • 8000 houses destroyed
                • 73,000 damaged
              • $2.7 billion worth of damage in 1991 and 1992
        • Pacific plate being subducted by Eurasian plate
        • Hydro-meteorlogical
          • Typhoon Haiyan (Typhoon Yolanda)
            • 8th of November 2013
            • Strongest ever recorded typhoon
            • Category 5 super typhoon
            • It killed 6,268 people
            • $2.86 billion worth of damage
    • California
      • 40 million people
        • Population density 242/sq mi
      • Geophysical hazards
        • San Andreas fault is a conservative plate boundary
          • This is where two plates (North American and Pacific) slide past each other in the same direction but at different speeds
          • Causes high magnitude earthquakes. The pressure builds up with the plates sliding past each other.
            • When the pressure is too much the plates release they can trigger a high magnitude earthquake, depending on the amount of time the pressure has been building up.
            • Northridge earthquake in Los Angeles
              • 17th January 1994
              • 6.7 magnitude
              • 57 people killed
              • 12,599 buildings damaged
              • 9000 homes and buildings without water for several days
              • $20 billion worth of property damage
            • Loma Prieta earthquake, San Francisco
              • 17th October 1989
              • 7.1 magnitude
              • 63 people killed
              • $6 billion of damages
              • 1918 homes destroyed
