Vulnerability SR-4
Standing susceptibility-to-harm data per area, across physical, socio-economic, and environmental dimensions — combined with Exposure to produce Risk.
Vulnerability — Analamanga
| Dimension | Indicator | Rating |
|---|---|---|
| Physical | Substandard housing share | Elevated |
| Physical | Flood-plain settlement density | High |
| Socio-economic | Poverty rate | Elevated |
| Socio-economic | Access to early warning information | Moderate |
| Environmental | Deforestation / watershed degradation | Moderate |
Vulnerability is a standing characteristic of the area, not a live hazard reading — it changes slowly and is reviewed periodically, not per alert.
