| Abstract |
The purpose of this study was to help making disaster prevention policy in North Korea. North Korea has remained for decades without
maintenance, repair and replacement of infrastructure. As a results, many buildings and facilities like roads, rails, bridges are old and
structurally weak. These factors seriously damage North Korea’s lives and properties in the event of a natural disaster. And also, due to the
limitation of data collections, North Korea researchers hasve not been actively conducted. This study overcame the limitations of North Korea researches,
such as the problem of data collections, and made it possible to produce highly accurate results. In this study, there are three steps for
assessing natural disaster risk in North Korea. First, 13 indicators were selected by reviewing the indicators used in the previous studies and
determining whether data could be constructed for each subregions. Second, The weight for 13 indicators was calculated using the entropy
method. This method excludes the subjective judgement of the researcher and improves the accuracy of the research by evaluating the
importance using only data. Third, the risk index for 188 regions between 0 and 1 was calculated. Spatial analysis of the hazardous area was
performed by assigning a risk rating between 1 and 5 using the natural breaks classification method. As a result of this study, 74 Intensive
Disaster Management Region in the eastern and western coastal areas and Pyongyang were selected. |
