Remote sensing is an important technology in disaster preparedness because it provides timely, accurate and large-scale information about the Earth’s surface and environmental conditions. It involves collecting information about the Earth without direct physical contact, mainly through satellites, aircraft, drones and other sensors. In disaster management, remote sensing helps identify hazards, assess vulnerable areas, monitor environmental changes and support authorities in preparing suitable response strategies. One of the major applications of remote sensing is hazard identification and mapping. Satellite images can be used to identify areas that are vulnerable to floods, landslides, cyclones, droughts, forest fires and earthquakes. Digital elevation models and satellite-based data help identify low-lying areas, steep slopes, drainage patterns and other physical features that may increase disaster risk. Such information helps disaster management authorities prepare hazard and vulnerability maps. Remote sensing is particularly useful for flood preparedness. Satellite images can provide information about rivers, drainage systems, flood-prone plains and changes in water bodies. By analysing rainfall, soil moisture and surface water
