Disaster hotspot - >1 hazard, hazard vulnerability e.g. loss of property + lives
Disaster hotspots: CALIFORNIA
- Capacity to cope = high (household income = $61,000)
- Population = 37m
- Hazards: earthquakes, coastal erosion, floods, wildfires, earthquakes
- Earthquakes - conservative plate boundary, shallow-focus, San Andreas Fault, LA has soft sediments
- Flooding + landslides - El Nino winter storms -> San Gabriel river flooding
- Droughts - arid Mediterranean climate
- Coastal erosion - threatens coastal homes
Disaster hotspots: the Philpinnes
- Capacity to cope = medium (middle-income = GDP/capita = $4,000)
- Population = 93m
- Hazards: earthquakes, volcanoes, floods, cyclones
Why are the impacts severe?
- Vulnerable pop - at sea level in poor buildings
- Poor disaster mitigation policies
- High magnitude hazards
- Isolated islands - no warning
- Tropical cyclones - 7k islands in tropical cyclone belt, 20 storms/yr. 2011 = Typhoon Washi -> flooding = 1250 deaths (slum housing at riverbank), 500k homes lost…
