1.3 Erupted in 1991 many people were evacuated, buildings collapsed, crops destroyed
2 Earthquakes
2.1 Philippine plate and the Eurasian plate can become locked together causes pressure to build up the jerk causes and earthquake
2.2 Can also occur at fault lines in the area where the plate cracked under pressure
2.3 They happen daily but can't be measured because there too little
2.4 Magnitude of 7.8 occurred killing over 1500 people
3 Landslides
3.1 Get lots of rain and the areas with steep slopes experience landslides
3.2 Can also be triggered by earthquakes
4 Typhoons
4.1 Have 10 typhoons every year
4.2 Developed in the pacific ocean and move westward over the island
5 Tsunami

7 Flooding
7.1 During the wet season floods can be caused by Typhoons and heavy rain
8 Population is vulnerable
8.1 Densely populated area greater risk of disaster
8.2 Population pressure lead to deforestation causing more landslides
