- 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
- Mount Pinatubo eruption
- High magnitude earthquakes
- 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
- Typhoon Haiyan (Typhoon Yolanda)
- Geophysical Hazards
- Almost 100 million people
- 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
- San Andreas fault is a conservative plate boundary
- 40 million people
- The Philippines
