Natural Hazards
- Typhoons are annual occurrences and the most frequent cause of disaster in the Philippines, having a severe impact on large parts of the country.
- Storm surges are atmospheric disturbances manifested in strong winds accompanied by rain and often by thunder and lightning, causing severe damage to coastal areas.
- Floods are the overflowing of excessive water onto an area which is normally dry, disrupting economic and social activities of the people.
- Volcanic eruptions are the process where molten rock materials are emitted or ejected, resulting in the displacement and evacuation of people, damage to properties, and loss of lives.
- Earthquakes are ground vibrations caused by volcanic activity, triggering landslides, and strong earthquakes may result in severe destruction of properties and infrastructure.
- Tsunamis are very large ocean waves caused by underwater earthquakes or volcanic eruptions, affecting Philippine coastal areas up to four meters above sea level.
- Landslides are the dislodging and falling of a mass of land and rocks, triggered by excessive rainfall or earthquakes.
- Droughts are long periods without rainfall, causing damage to crops, economic losses, and disaster declarations.
Man-Made Disasters
