    Abstract
    : Over 90% of global trade is done by shipping the world, the marine sector supports the transportation of a variety of critical items while balancing the global economy and keeping countries united in such a complex global market. Sri Lankan ports are strategically positioned ports for vessels going from west to east and east to west. The X-Press Pearl ship Explosion recorded on the 20th of May 2021 was investigated under the study by utilizing the Geographic Information Systems in the spatial domain. It severely polluted some of the coastal zones of Sri Lanka including Colombo, Kalutara, and Galle due to its chemical explosion and oil spreading. Under the research, we explored the marine species wash-out incident through records and reports on social media and news reports as the main source of data. First, all data is stored in the spatial database before the analysis and along with the location coordinates. Then the spatial analysis was carried out in the Arc GIS 10.5 platform and generated maps to illustrate the pattern of expansion. According to the study, it has found out the most vulnerable areas were western and southern coastal regions while some incidents were recorded in the east part as well. The data collected and reported on social media or news was utilized in the data collection phase and it indicates the public involvement in disaster management practices. Further, data analysis done through the GIS context would be significant in the decision making and implementation phases as a future direction of the study
