Oil Spill Hazards : Detection of Peruvian Oil Spill Using Sar Data and Analysis of its Health Implications

A multi-hazard event occurred off the coast of Peru in January 2022 caused chiefly by an underwater volcanic eruption near Hunga Tonga island in the Pacific. It triggered an earthquake and tsunami which further caused an oil spill event in a refinery in Peru. This research work is an attempt to look at disasters from a multidisciplinary and transdisciplinary point of view in order to understand their impact holistically. It employs Geospatial tools to detect oil spills using SAR data. WHO’s One Health Approach has been used to analyse the impact of oil spill disasters on the health of humans, animals and the environment in an integrated manner. It is concluded from the data and the results obtained after processing the data on the SNAP platform that the VV-polarised image is more suitable for oil spill analysis than the HH-polarised image. Water that has been contaminated by an oil slick may often have lower pixel values or seem darker. On the health impact of oil spills, the overall impact of oil spills was analysed and an attempt has been made to put it within the framework of One Health
