摘要：After the 2016 Gyeongju earthquake and the 2017 Pohangearthquake struck the Korean peninsula, securing financial stabilityregarding earthquake risks has become an important issue in South Korea. Many domesticresearchers are currently studying potential earthquake risk. However,empirical analyses and statistical approaches are ambiguous in the case ofSouth Korea because no major earthquake has ever occurred on the Korean peninsulasince the Korean Meteorological Agency started monitoring earthquakes in 1978.This study focuses on evaluating possible losses due to earthquake risk inSeoul, the capital of South Korea, by using a catastrophe model methodologyintegrated with GIS (Geographic Information Systems). Buildinginformation, such as structure and location, is taken from the buildingregistration database and the replacement cost for buildings is obtained frominsurance information. As the seismic design code in the KBC (Korea BuildingCode) is similar to the seismic design code of the UBC (Uniform Building Code),the damage functions provided by HAZUS-Multi-hazard (HAZUS-MH) are used to assess the damagestate of each building in event of an earthquake. A total of 12 earthquake scenariosare evaluated by considering the distribution and characteristics of activefault zones on the Korean peninsula and damages, with total loss amounts arecalculated for each of the scenarios. The results of this study show thatloss amounts due to potential earthquakes are significantly lower than thoseof previous studies. The challenge of this study is to implement anearthquake response spectrum and to reflect the actual asset value of buildingsin Seoul.
