High Resolution 1:10,000 scale Mapping Strategy of Multi ... - NDMA

Moderate Hazard Zone (mapping priority P2)
The areas, which have been frequently hit by cyclonic storms with intensity T2
have been categorized as vulnerable area and given Moderate priority (P2) for
mapping. These areas are affected by high rainfall, flooding and damage due to high
winds exceeding 60 km/hour. Normally these areas are adjacent to sever cyclonic
affected areas, where sever cyclone loose their intensity and remain in cyclonic
storm category. Mostly the districts of West Bengal, Orissa, Bihar and Tamil Nadu in
east coast and Karnataka, Maharashtra and Gujarat fall in this category.
Low Hazard Zone (mapping priority P3)
The areas, which have been frequently hit by deep depression with intensity
T1 and above have been categorized as low vulnerable area and given Low priority
(P3) for mapping. These areas are affected by moderately high winds exceeding 50
km/hour above and high rainfall.
