Question

How is remote sensing useful in disaster management?

Answer 1

1. Remote sensing technology is highly used in disaster management to study the effects of earthquakes, tsunamis, cyclones, volcanic eruptions, floods, and wildfires.
2. The preliminary data is retrieved from satellites like LANDSAT, CARTOSAT, OCEANS, etc.
3. Fire and flood details can be extracted and delivered to relevant authorities within two hours of satellite image capture.
4. E.g. major earthquakes in China and New Zealand, bushfires in Victoria, and floods in Kerala.
5. Dynamic phenomena such as floods, movement of wild animals, shoreline changes, finding lost ships, and planes.
6. Researchers use satellite imageries for these.
