GIS-based Spatio-temporal Analysis of Marine Accidents Database in the Coastal Zone of Korea

초록

Maritime transportation, including the use of boats, ferries and ships for the transportation, fishing and recreational activities, currently plays an important factor in global economy and is increasing annually. With increase of maritime transportation, the occurrences of marine accident are also increased. Based on worldwide statistical database of marine accidents, Marine Casualties and Incidents (MCI) module published by Global Integrated Shipping Information System (GISIS), the second highest number of accidents have occurred in the coastal zone around East Asian countries, China, Japan and Korea. Especially in Korea, there are many major accidents such as sinking, collision, capsizing, stranding, grounding and explosion etc. which can cause huge damage of human life and property. This study analyses the spatial distribution of marine accidents in more details for coastal zone of Korea in order to illustrate and predict the vulnerable coastal zone for improving costal safety management, planning and decision making. A detailed database with major and minor accidents around coastal zone in Korea collected by the office of Korea Coast Guard (KCG) from 2007 to 2014 were used for the geo-spatial analysis in Geographic Information System (GIS) environment. Two types of spatial analysis, Buffer and Cluster analysis, were performed to visualize the distribution of marine accidents and then to determine the high accident and safety deficient areas. The results from this study can help to determine the common reasons of marine accidents in the coastal zone of Korea, with high vulnerable zone of accident, for risk management, accident prevention and response planning in the future.
