Abstract
In this study, we conduct an estimation study of the damage costs, recovery costs, and human losses in the case of natural disasters in the Republic of Korea. This research method analyzed human losses, damage costs, and recovery costs caused by natural disasters that swept across the Republic of Korea over the past 16 years, from 2000 to 2015, including extreme wind, heavy snowfall, typhoon, wind wave, and heavy rainfall. Damage status and trend of occurrence were reviewed for each year’s human losses, damage costs, and recovery costs. We propose a calculating equation of the linear regression equation that estimates damage costs and recovery costs considering human losses. The correlation coefficient was 0.898 for the estimation of human losses and damage costs, and 0.889 for the estimation of human losses and recovery costs. In addition, the correlation of both equations was found to be 166% of damage costs when calculating recovery costs. The results of this study can be used as descriptive statistical data to estimate damage costs and recovery costs according to human losses in case of natural disasters.
Highlights
When natural disasters strike, they generate human losses and property damage, both in cases of ordinary meteorological phenomena including rain, snow, and wind, and massive climate phenomena such as typhoon, heavy rainfall, heavy wind, and heavy snowfall due to energy imbalances caused by the Earth’s rotation
Many studies have proposed an equation that calculates the direct damage costs caused by many types of natural disasters such as typhoon, heavy snowfall, extreme wind, and heavy rainfalls, but an equation that considers the economic effects caused by abnormal climate due to climate change [8,9,10,11,12,13,14,15]
The estimation equation proposed in this study is an equation for estimating damage costs and recovery costs based on human losses caused by natural disasters
Summary
They generate human losses and property damage, both in cases of ordinary meteorological phenomena including rain, snow, and wind, and massive climate phenomena such as typhoon, heavy rainfall, heavy wind, and heavy snowfall due to energy imbalances caused by the Earth’s rotation. Heavy rainfall accounts for most damages associated with natural disasters in the world, a variety of damages are specific to the geographical and climate characteristics of certain nations, such as those caused by typhoon, hurricane, wildfire, and earthquake [4,5,6,7]. Many studies have proposed an equation that calculates the direct damage costs caused by many types of natural disasters such as typhoon, heavy snowfall, extreme wind, and heavy rainfalls, but an equation that considers the economic effects caused by abnormal climate due to climate change [8,9,10,11,12,13,14,15]
