Table 2 Criteria considered to control the tsunami buildings vulnerability, their corresponding weight factors (Fw.i) and classification factors (Fc.b for building condition, Fc.i for inundation zone, and Fc.s for sea defense)
Building | Inundation zone | Sea defense | ||||
|---|---|---|---|---|---|---|
Weight Factor (Fw.i) | 3 | 2 | 1 | |||
Class | Condition level | Fc.b | Corresponding Flow depth (m) | Fc.i | Resistance level | Fc.s |
A | Very good | 1 | 0–4 | 1 | Good | 1 |
B | Good | 2 | 4–8 | 2 | Medium | 2 |
C | Medium | 3 | 8–12 | 3 | Bad | 3 |
