The extremely severe cyclone ‘Amphan’ made landfall on 20 May 2020 in the state of West Bengal, India causing widespread damages. The present study describes the potential use of multi-mission satellite datasets in delineating the cyclone disaster footprints and assessing the impact in near real-time. Flooding due to the cyclone was monitored and mapped continuously from 21 to 27 May 2020 using synthetic aperture radar (SAR) data of multiple satellites. It was observed that about 2.09 lakh hectares in ten districts of the state was affected by cyclone-induced inundation. East Medinipur district was the worst affected with 83,402 ha inundated during the cyclone. The inundation maps were disseminated to the disaster management authorities in near real-time for effective disaster management to aid in relief and rescue operations.

Abstract


The extremely severe cyclone ‘Amphan’ made landfall on 20 May 2020 in the state of West Bengal, India causing widespread damages. The present study describes the potential use of multi-mission satellite datasets in delineating the cyclone disaster footprints and assessing the impact in near real-time. Flooding due to the cyclone was monitored and mapped continuously from 21 to 27 May 2020 using synthetic aperture radar (SAR) data of multiple satellites. It was observed that about 2.09 lakh hectares in ten districts of the state was affected by cyclone-induced inundation. East Medinipur district was the worst affected with 83,402 ha inundated during the cyclone. The inundation maps were disseminated to the disaster management authorities in near real-time for effective disaster management to aid in relief and rescue operations.
