The hazard results will then overlaid with population data in the overall assessment <strong>of</strong><br />

multi-hazard risk. For more details , please refer to Annex- II.<br />

CRITERIA FOR PRIORITY ZONES<br />

For the major types <strong>of</strong> disasters, i.e. earthquake, landslide, cyclones and floods, some<br />

criteria can be considered which are indicated in Table 2.3.<br />
