Hazard Hotspot: PHILIPPINES
- The Philippines:
- Pop: 97,000,000
- 7000 small
islands
- Belt of tropical cyclons
- Lower middle income family
- Lies on a boundary between
two tectonic plates: the
Philippines and the Eurasian
- population densities are
high: 240 people per km2
- many are poor and
living on the coast
- This makes them vunerable
to locally generated tsunamis
and typhoon generated storm
surges
- Pop: 97,000,000
- Mount Pinatubo June 1991
- biggest the world had seen for 50 years
- sent a cloud of ash 20 km into the air
- spread over south east Asia over 3 days
- The second eruption on the 15th of June was cataclysmic
- a dome on the side of the volcano collapsed
- creating a pyroclastic blast and huge lahars

- The second eruption on the 15th of June was cataclysmic
- spread over south east Asia over 3 days
- some evacuees died in camps when they were exposed to disease
- 350 people died including 77 in the lahars
- 350 people died including 77 in the lahars
- 80000 hecters of farm land = buried under ash
- disrupting livelihoods of 500000 farmers and their family members
- disrupting livelihoods of 500000 farmers and their family members
- economic losses were US $710 million dollars, mainly agriculture and property
- 20 million tons of sulfur dioxide were injected into the
stratosphere, and dispersal of this gas cloud around
the world caused global temperatures to drop
temporarily (1991 through 1993) by (0.5°C).
- biggest the world had seen for 50 years
- Destructive plate Boundary
- The Eurasian plate is subducted underneath the Eurasian, creating the deep manila trench
- Plates move as a series of jerks- friction
- As the subducted plate melts in the earths mantle, the magma forms a magma chamber
- Combines with gasses and becomes explosive
- Magma solidifies below the earths surface and produces a solid cap over the volcanoes vent
- Pressure grows beneath it
- Erupts with huge force
