5. ELABORATION OF MAIN DISASTERS

Table-1 shows the return period of the main disasters and Table-2 illustrates the Average Annual Loss (AAL) by these hazards. Flood and earthquakes have caused a great annual loss to the country as described by Figure-5.1. Figure-5.2 represents the recurrence of these disasters and flood has the highest frequency followed by storm. Figure-5.3. represents the percentage of deaths caused by these disasters and, as shown, flood has caused a highest number of deaths as compared to all other disasters.
