Case Study- Philippines
- Volcanoes
- Near destructive
plate boundary
Philippine plate being
subducted by the
Eurasian plate
- Islands were formed
by combination of
folding at the boundary
and volcanoes were
formed from magma
risen to the surface
- Erupted in
1991killed 350
deaths and 58000
were evacuated
- Near destructive
plate boundary
Philippine plate being
subducted by the
Eurasian plate
- Earthquakes
- Philippine plate and
the Eurasian plate can
become locked
together causes
pressure to build up
the jerk causes and
earthquake
- Can also occur at
fault lines in the
area where the
plate cracked
under pressure
- In the last 400 years there have
been 65 destructive events
- The worst earthquake was in
1990 near Rizal city, caused
1700 deaths and cost £300
- Philippine plate and
the Eurasian plate can
become locked
together causes
pressure to build up
the jerk causes and
earthquake
- Landslides
- Get lots of rain and
the areas with steep
slopes experience
landslides
- Country experiences a
tropical monsoon climate
which in combination with
deforested hillsides leaves
the area very prone to
landslides
- Country experiences a

every year
- Tsunami
- Earthquakes in the
surrounding ocean
could cause a
tsunami
- 1976 earthquake of
7.9 caused a tsunami
killed 5000 people

- Occur when the wet
season hasn't bought
enough rain to last the
dry season
- have distinct wet and dry
seasons

- During the wet season floods can
be caused by Typhoons and
heavy rain
- During the wet season floods can
be caused by Typhoons and
heavy rain
- Population is vulnerable
- Densely populated
area greater risk of
disaster
- Total population 91 million: Density 240 per km2
- Total population 91 million: Density 240 per km2
- Population
pressure lead to
deforestation
causing more
landslides
- Fast growing
economy people still
live below poverty line
- GDP per capita is only $5000
- GDP per capita is only $5000

area greater risk of
disaster
