Coastal regions are highly susceptible to the effects of global warming, including rising atmospheric and sea surface temperatures, increased cyclone frequency, level rise. Thus, it is imperative examine coastal vulnerability minimize impact multiple hazards protect resources, such as mangroves. Particularly in India studying zones Andaman Nicobar Islands which fall seismic zone V critical for conservation efforts. We conducted analysis impacted by 2004 earthquake, causing varying degrees ground upliftment subsidence. compared among sites that experienced uplift, no change, subsidence (the southern portion). Our utilized Mangrove Vulnerability Index (CVI MVI) measure compare six distributed along uplift gradient. High-resolution satellite imagery WorldView-2, 3, GeoEye-1 from year 2022 on this study. The CVI MVI offers a good way vulnerabilities across offer insights better management. results indicate approximately 34% grids over 23% mangrove all extremely vulnerable. Subsided were found be more vulnerable than uplifted zones. These findings suggest large-scale natural disturbances tectonic displacement have potential vegetation cover can become even In conclusion, our study emphasizes importance analyses regions, especially areas prone activity. direct implications restoration efforts underscore need continued monitoring mitigation safeguard resources long-term sustainability.
