Hazard Mapping — Prelims Strategy

Prelims Strategy

For Prelims preparation, focus on memorizing specific facts and technical details that UPSC frequently tests. Key areas include: institutional responsibilities (GSI for seismic, IMD for cyclone, CWC for flood mapping), technological applications (GIS, remote sensing, LiDAR uses), and specific Indian initiatives (seismic zonation maps, cyclone hazard atlases).

Create a comprehensive fact sheet covering return periods, probability concepts, and technical terminology. Practice elimination techniques by understanding common traps - UPSC often confuses students about which technology is used for which hazard type, or which agency is responsible for specific mapping activities.

Pay special attention to recent technological developments and new satellite launches that enhance mapping capabilities. Study the integration between hazard mapping and other disaster management components, as UPSC frequently tests these connections.

Memorize specific examples of hazard maps (IS 1893 seismic zones, IMD cyclone hazard atlas) and their applications in policy and planning.
