Explain Hazard Zonation Map

Ndma guidelines are being followed for landslide hazard zonation lhz maps at 1.

Explain hazard zonation map. Zonal mapping of landslide areas will surely allow authorities to identify those places that are vulnerable to landslides. A hazard map is a map that highlights areas that are affected by or are vulnerable to a particular hazard. They are typically created for natural hazards such as earthquakes volcanoes landslides flooding and tsunamis hazard maps help prevent serious damage and deaths. National remote sensing center nrsc department of science and technology dst council of scientific and industrial research csir indian institute of india iits universities have done.

50 000 scale and progressively larger scales for specific areas. Uses of hazard maps. The methodology adopted for 1 10000 scale landslide hazard zonation mapping is based on an extensive field study and evaluation of six causative factor attributes and their sub factor elements and hence limited to the areas with potential to development and extremely high vulnerability to landslides view a sample 1 10000 scale map. An empirical approach was used to map and evaluate landslide susceptibility.

Hazard maps are created and used in conjunction with several natural disasters. Role of zonal mapping in mitigating landslides identifying vulnerable areas. Remote sensing data is further used to delineate drainage pattern photo lineaments structural features lithologial. In the present study pre and post earthquake remote sensing data has been used to prepare landslide inventory.

Five layers of data with 30 30 m resolution grid were superimposed to create the landslide susceptibility map.
