“…Based on historical and instrumental earthquake data, they analyzed the damage due to virtual earthquakes that may occur in areas, such as Hongseong, Yesan, and Boryeong, and predicted the degree of damage to residential and commercial concrete buildings as well as human casualties. Jeong et al [20] estimated direct damage and economic losses by comparing the Korea Building Act with the response spectrum of the scenario earthquake to evaluate seismic loss in Gangnam-gu, Seoul, Korea.…”

In this study, a global temperature rise by +1.9 to 5.2 ℃ was expected at the end of the 21st century due to greenhouse gas emissions based on a report from the Intergovernmental Panel on Climate Change, and a 1.6 ℃ increase in annual average temperature in Korea over the last 109 years (1912 to 2020) was confirmed. These climate changes have increased heat waves and extreme climate indices worldwide, and natural disasters have increased in Korea due to irregular changes in heat waves and precipitation. In addition, this study on disaster damage estimation was conducted using Hazards-US-Multi-Hazard (HAZUS-MH), a disaster damage assessment platform used in the United States. HAZUS-MH was selected because it is stable and robust for various disaster scenarios as well as specific geographical and climate conditions and is reliable for disaster management and response even though it has difficulty reflecting specific domestic environments. The results showed that seismic damage reduction costs can be significantly decreased through the integration of early warning and preventive measures under the scenario of Pohang earthquake magnitude 5.4. This study provides insight into domestic climate change and disaster management and emphasizes the need for future response and model development. An effective response to climate change is expected to play an important role in ensuring national and regional safety and stability.

“…Therefore, it is necessary to provide proper datasets reflecting the Korean environment, such as the geological environment, structures, and uses of buildings, in order to evaluate the loss assessment properly. In the study by [10], only the direct economic damage of buildings caused by strong ground motion was estimated, which does not reflect the ground liquefaction and indirect damages that reflect the characteristics of the region. The studies by [11,12] presented the damage prediction and inventory construction method in a specific area and introduced the necessity of a long-term project caused by inducing the system to expand the inventory [13].The loss assessment uses a variety of data, such as demographic figures, building-integrated information, and others, gathered and used at the national level.…”

To cope with natural disasters and their impact, various types of risk assessment tools have been developed to assess hazards from a scientific point of view as well as the socioeconomic impacts of a hazardous event. Because most of the assessment tools have been developed using local and regional characteristics, there are limitations when applying special cases consisting of various disaster-related datasets in Korea. In this paper, we collected open data scattered among various institutions and guaranteed data interoperability through a standardization process considering various formats. In addition, this study presents a scalable design method and implementation of a database system which can be easily employed in Korean loss estimation due to natural hazards. The proposed database system will be of great help in predicting the disaster scale and degree of damage, in supporting decision-making to minimize damage, and could serve as a data platform of disaster risk reduction and prevention.Information 2020, 11, 8 2 of 19 on the degree of damage, and calculate the number of refugees and the number of people requiring shelters. To perform a loss assessment, data representing the information of the damaged area, such as buildings and population, are required. Relevant studies conduct research and analysis using data provided in the forms of files and databases by the country.In South Korea, studies are being conducted using disaster damage statistical data, relevant research data, and actual measurement data. For earthquakes; however, earthquake-related data for estimating losses are insufficient. Therefore, analyses are conducted based on HAZUS-MH, which is a loss assessment tool of the Federal Emergency Management Agency (FEMA), using a large amount of accumulated actual data, earthquake-related data provided by the tool, and domestic and overseas studies. In order to utilize these specific data sets in various applications, such as HAZUS-MH or ERGO, a lot of time is required to turn the data into useful information through the initial steps of data cleaning, preparation, and preprocessing.HAZUS-MH is developed by the Federal Emergency Management Agency (FEMA) and is used in many other regions for estimating losses after natural hazards, including earthquake, flooding, fire, and hurricane. In damage estimation studies caused by natural disasters in the Korean peninsula, Kang et al.[5] estimated loss estimation by using HAZUS-MH and ShakeMap of USGS (United States Geological Survey), and Yu and Jo et al. [6,7] investigated flood loss estimation using HAZUS-MH. Besides, Scawthron and Hancilar et al. [8,9] analyzed HAZUS-MH-based loss assessment in Canada and Oman.As the earthquake-related data provided by HAZUS-MH (and the weight data used for loss assessments) reflect the environment and condition of the corresponding country, the data are different from those of the Korean environment. Therefore, it is necessary to provide proper datasets reflecting the Korean environment, such as the geological environment, s...
