Terms

Exposure
The share of a barangay, or of the people and assets in it, that lies within a hazard-susceptible area.
Sensitivity
How badly what is exposed would be affected — informal settlement, light-material dwellings, dependants.
Adaptive capacity
The local government's ability to reduce or absorb the impact. Scored A to D, where A is strongest; the score is inverted so that a higher number always means worse.
Vulnerability
Sensitivity divided by adaptive capacity, banded to 0.25, 0.5, 0.75 or 1.0.
Severity of consequence
The mean of exposure and vulnerability.
Risk score
Likelihood multiplied by severity of consequence, 1 to 16.
Susceptibility class
The agency's own rating of an area — for MGB, VHF to LF for flood and VHL to LL for landslide. Published verbatim here, never reworded.
