Urban Multi-Hazard Risk Analysis Using GIS and Remote Sensing : A Case Study of a Part of Kohima Town, India

An urban hazard is a potentially damaging phenomenon that threatens a city, its population and related socioeconomic activities. There is not only a single hazard, but many hazards to which a city is vulnerable, though the probability of occurrences and intensity may differ from hazard to hazard. The book tries to address the recurrent geo-hazards in a typical hill town using Remote Sensing and Geographic Information System techniques. It also tries to see how a rapid pre-damage assessment can be carried out in a situation with scarcity of spatial data within a short period of time, by integrating available data with historical data on occurrences of natural disasters. The case study was conducted in a part of Kohima Town, Nagaland, in the North-Eastern parts of India, which lies in the zone V of the seismic map of India. Three hazards namely: seismic, landslide and fire were taken for analysis and an estimation of buildings that may suffer damage during an earthquake, landslide and fire were carried out.
