Impact Assessment of FENGAL Cyclone in Tamil Nadu By Using ARCGIS

Abstract - Cyclones are powerful natural disasters that frequently impact the coastal regions of Tamil Nadu, causing significant socio-economic and infrastructural damage. The 2024 Fengal Cyclone severely affected the Cuddalore and Viluppuram districts, highlighting the urgent need for advanced disaster risk assessment and management strategies. This study assesses the impact of the Fengal Cyclone in Tamil Nadu using Geographic Information System (GIS) techniques, specifically ArcGIS, to map and analyze cyclone vulnerability zones. By integrating key physical parameters such as slope, elevation, land use and land cover, drainage density, and precipitation, the research identifies and classifies flood risk zones along the coast. The resultant thematic maps provide spatial insights into cyclone risk, enabling more effective disaster preparedness, mitigation planning, and resource allocation. The findings support local authorities, urban planners, and disaster management teams in developing targeted interventions to reduce the adverse effects of future cyclonic events in the region.
