- Multi-Hazardous Environment
- Volcanoes
- Philippine Plate subducted beneath Eurasian
- Mount Pinatubo 1991
- 700 deaths, 200 000 homeless, buildings collapsed, crops destroyed, agricultural land ruined by ash
- 22 active, 30% live within 30km of a volcano
- Earthquakes
- Occur at plate boundary and along fault lines
- Luzon 1990
- 7.8 magnitude, 1500 died, 160 buildings collapsed in city of Baguio alone
- Landslides
- High rainfall, steep topography, deforestation
- Storm Nalgae 2022
- 20 rain-induced landslides, 80 000 in need of shelter
- Tsunamis
- Moro Gulf 1976
- 7.9 magnitude earthquake caused a tsunami killing 8 000 people across 700km of coastline (up to 9m high)
- Moro Gulf 1976
- Social Risks
- dense population - 340/km^2
- Rapidly developing
- 25% live in poverty - most on the coast
- Economic Risks
- Heavily reliant on primary sector (fishing/agriculture) so major losses
- Low capacity to cope - reliant on aid
- Environmental Risks
- Major plate boundary, Pacific coastlines
- Deforestation (result of development) so reduced interception and unstable land
- Vulnerable settlements - Angeles near Mt P
- Resilience
- Previous experience (prepared)
- Adaptations
- Making buildings hazard-resistant, post-disaster support
- Management
- Education - PHIVOLCS
- Legislation - land use planning, building regulations, 70% disaster spending must be long term
- Tropical Storms
- Pacific Ocean location
- Typhoon Haiyan 2013
- 6201 killed, 313km/h winds, $5.8bn costs, 1.9m homeless, Tacloban airport damaged, crops and fishing damage
- Earthquake, Haiyan and flooding in 3 months killed 6488
- Typhoon belt - 15 per year
- Mitigation
- Preventative measures (land use planning), but little focus on this - mainly post-disaster support
- Volcanoes
- Location
- SE Asia, Pacific Ocean
- destructive plate boundary ((Pacific plate subducting below Eurasian)
