Introduction: For decades, trends of natural disasters has changed due to advance of prevention technologies, infrastructure and global warming. The aim of this study is to demonstrate the trend of natural disaster in Korea. Material & Methods: Annual reports from governmental offices, papers from journals were collected. We collected data of disaster categories, dates of events, location, mortalities and injuries related to the event, and events from the sea were excluded. We performed a time series analysis to evaluate the trend of disaster occurrence and its effects. Results: Overall, 534 events met the criteria and were included for analysis. There have been 51 (9.5%) typhoons, 219 (41%) heavy rains, 58 (10.9%) heavy snow, 161 (30.1%) strong winds, and 43 (8.1%) uncategorized natural events. 6,831 casualties were reported as results from natural disasters: 4,129 deaths and 2.702 injuries. The leading causes of casualties were heavy rain 3,401 (49.8%). However, for each event, typhoons were most dangerous with an average of 51.1 (SD:6.21) casualties per event. Trend analysis showed that the number of natural disasters decreased from 35 (1985) to 4 (2002) (p<0.001) and increased to 22 (2012) (p=0.001). Related casualties decreased from 325 (1985) to 53 (2012) (p=0.002), with a significant drop in 2004. Conclusion: The number of natural disasters had minimized in 2002.
