HAZUS-MH is a GIS-based computer program that estimates potential losses from multi-hazard phenomena: earthquakes, floods and hurricanes. With respect to seismic disaster, characteristics of a hypothetical or actual earthquake are entered into HAZUS. Then HAZUS estimates the intensity of ground shaking and calculates the correspondent losses. In this study, HAZUS was used as a part of the preparations of the future seismic events at a coastal plant facility area. To reliably characterize the target facility area, many geotechnical characteristics data were synthesized from the existing site investigation reports. And the buildings and facilities were sorted by analyzing their material and structural characteristics. In particular, the study area was divided into 17 blocks taking into account the situation of both land development and facility distribution. The ground conditions of blocks were categorized according to the site classification scheme for earthquake-resistant design. Moreover, seismic fragility curves of a main facilities were derived based on the numerical modeling and were incorporated into the database in HAZUS. The results estimated in the study area using HAZUS showed various seismic damage and loss potentials depending on site conditions and structural categories. This case study verified the usefulness of the HAZUS for estimating earthquake losses in coastal facility areas.

대형태풍 카트리나가 준 주요 교훈 중의 하나는, 위험도 분석에 기반한 종합적인 재해경감 프로그램의 중요성이다. 미국에서는 이를 위해 다양한 위험도 분석(risk analysis) 프로그램 개발에 노력해 왔다. HAZUS(Hazarda-US) 프로그램은 대표적인 자연재해 예측 시스템으로서, 위험요인 파악(hazard identification), 지역사회의 취약성 분석(vulnerability of the society), 그리고 피해결과예측(loss estimation)의 세 가지 요소로 구성된다. 1992년 지진을 대상으로 개발된 이 프로그램은 현재, 지진 홍수 허리케인 윈드에 대해 피해예측을 할 수 있는 HAZUS-MH MR3가 사용 중에 있다. FEMA에서는 주정부에서 HAZUS를 활용, 피해 예측에 기반한 재해경감 정책을 추진할 수 있도록 다양한 재정적 기술적 지원을 하고 있다. 이에 따라, 2004년 머릴랜드 주에서는 미국 최초로 주 전역에 걸친 홍수피해 예측을 실히하고 이를 바탕으로 다양한 경감정책을 추진하였다. 머릴랜드 주정부에서 Salisbury 대학에 의뢰하여 수행한 홍수 피해 예측 과정은, 조사구역 및 위험요인(홍수) 결정, 사용 데이터 확정, 수문학적 분석, 수리학적 분석, 피해예측(건물 용도별 피해면적, 건물 용도별 피해액, 건물 재질별 피해면적, 건물 재질별 피해액, 지역의 경제학적 피해)의 과정으로 수행되었다. 홍수피해 예측 결과, 100년 빈도 홍수가 재현될 경우, 주 전체 면적 중 13%이상의 지역에서 약 80조 이상의 피해액이 예측됨에 따라, 종합적인 재해경감 대책의 필용성이 제기되었다. 이에 따라, 머릴랜드 주정부에서는 홍수피해예측 결과를 토대로, 주정부 재해경감 예산 재분배, 홍수터 보호, 건물규제 강화, 토지이용계획 재조정 등 보다 과학적이고 종합적인 재해경감 프로그램을 추진하였다. 머릴랜드 주정부의 이번 연구는 주정부로서는 최초로 HAZUS를 활용하여 주 전역에 걸친 피해예측을 실시한 것으로서, 피해예측 시스템이 어떻게 주정부의 과학적 피해경감 프로그램에 기여할 수 있는 지를 보여주는 사례이다.

Korea is located away from plate boundaries which are not safe from earthquakes. However, having witnessed the large-scale earthquake in the Tangshan region in 1976 deemed as a safe plate, it should not be assured that Korea is absolutely safe from earthquakes. In addition, many seismologists have claimed that there indeed is a high possibility of earthquakes above mid scale that would occur in Korea. Because it is impossible to prevent earthquake, studies on seismic design and earthquake disaster control system are widely being conducted. However, studies on early response to earthquakes or recovery process are still very limited, and only a few studies for establishing earthquake damage evaluation system are being conducted. Thus, this study aimed to present essential data for establishing earthquake damage evaluation system that takes into account the real situation of structures in Korea. In this study, a nonseimically reinforced concrete apartment structure in Gangnamgu was selected as an standard type of such structures and its earthquake damage was estimated. The result of damage evaluation based on the derivation of vulnerability function and realtive story displacement was compared to that abtained using HAZUS Program Vulnerability Function.

Lifeline Damages induced by earthquake loading brings not only a structure damage but the communication problems by the interruption of various energy utilities such as electric power, gas, and water resources. Earthquake loss estimation systems in USA and Japan, called as HAZUS (Hazard in US) and HERAS (Hazards Estimation and Restoration Aid System), respectively, have been established for the purpose of efficient responding to the earthquake hazard. Sufficient damage records are required to establish these systems. However, there are insufficient data set of damage records obtained from previous earthquakes in Korea. In this study, according to the construction specifications of the pipelines in both Korea and USA, the behavior of both ductile and brittle pipelines embedded in dense sand overlying various soils, such as clay, sand, and gravel were examined with respect to the pipeline characteristics under various earthquake loadings. The applicability of pipeline damage prediction used in HAZUS program to Korea has been investigated.

Currently, according to the climate change, serious damage by typhoon has been occurred in the world. In this respect, the research on the prediction model to minimize the damage from various natural disaster has been conducted in several developed countries. In the case of U.S, various models to predict building damage costs have been used widely in many organizations such as insurance companies and governments. In South Korea, although studies regarding damage prediction model according to typhoon have been conducted, the scope has been only limited to consider the property of typhoon. However, it is necessary to consider various factors such as typhoon information, geography, construction environment, and socio-economy factors to predict the damages. Therefore, to address this issue, first, correlation analysis is conducted between various variables based on the data of typhoon from 2003 to 2012. Second, the damage prediction model by using regression analysis is developed based on suggested influence factors. The findings of this study can be utilized to develop the model for predicting the damage costs of buildings by typhoon like HAZUS-MH of US.
