• Increasing frequency and intensity of extreme events

• Hydrometeorological hazards pose a significant threat to all areas

in the Philippines:

- physical disruption of infrastructure

- human health effects

- significant economic losses and loss of lives

• With the past events, it is a “must” to review/update the building

codes and retrofit structures not conforming with the design

standards.

• Strict implementation of land-use zoning to restrict development in

identified high risk areas.
