How to read this assessment
The DHSUD framework builds a risk score from four measured quantities: how likely a hazard is, how much of a barangay it would affect, how sensitive what is there is to being affected, and how much capacity the local government has to cope. Exposure — the second of those — is what a hazard map can answer on its own, and it is what this draft contains. The other three come from the city and are listed in What Is Still Needed.
