In the ocean area surrounding the Korean Peninsula, the undersea earthquakes have occurred frequently during last decades. The eastern coast of the Korean Peninsula is very vulnerable to tsunami attacks which occur along the Western Coast of Japan. In special, the middle areas of the eastern coast of Korean Peninsula have been damaged due to the Central East Sea Tsunami occurred in 1983. Thus, tsunami hazard mitigation becomes an important issue at eastern coastal communities. The countermeasures against unexpected tsunami attacks are not sufficient because the government policy generally focused on not preventing but recovering. In this paper, a hazard map based on the field survey and tsunami evacuation simulation is developed to mitigate tsunami damage at Imwon port, which was severely damaged during the 1983 Central East Sea Tsunami.

The 2011 Japan Tsunami caused tremendous damage to coastal areas. Because of their drastic propagation speed and large run-up height, nearshore tsunami can cause catastrophic damages on coastal communities within a short time. It is necessary to establish the tsunami hazard mitigation to reduce human injury housing damage. The construction of Tsunami warning system and production of hazard map are needed for minimizing damage by tsunami.

The Headquarters for Earthquake Research Promotion (HERP) represents the upper-most level of Japan's earthquake disaster prevention governance. Its policy committee establishes the national earthquake investigation research promotion plan. The earthquake investigation committee of HERP collects survey geo-data and evaluates the research results of each earthquake disaster prevention agency. The establishment of an earthquake-related geo-resilience research strategy is both necessary and desirable for Korea. The concept of geo-resilience entails the ability to improve disaster resilience through the application of research results and the convergence of geoscience with science and technology (S&T) including the humanities and social sciences. The achievement of geo-resilience requires a national long-term roadmap and strategy for earthquake prediction research, the development of earthquake disaster prediction and prevention technology, Geo-ICT convergence technology development, implementation of a geocyber physics system (Geo-CPS), the use of geo-mimetics, and geoscientific R&D as it relates to local communities. Through such efforts, the national research institutes of Korea will be able to develop earthquake prediction capacities in relevant fields, reinforce proactive response capabilities, enhance community-level confidence in geodata and its research results, foster next-generation geoscientific manpower, and expand geoscientific infrastructure.

12월 20일, 성탄절 이튿날 지구촌은 최악의 대재앙을 실감했다. 인도네시아 수마트라 앞바다에서 발생한 M9.0의 강진과 함께 지진해일이 인근 연안에 내습하여 근 30만 명의 목숨을 앗아갔다. TV를 통해 비추어지는 참담한 모습만으로도 그 공포를 실감할 수 있었다. 온 세계가 지진해일의 공포를 느끼고, 그 위험에 대해 인식하기 시작했으며, 국제적 차원에서의 대책마련에 관심이 집중되고 있다. 지진해일 경보 미비, 피해자들 대부분이 지진해일에 대한 지식과 대처요령을 터득하지 못했으며, 저빈도 재해로서 피해국이 투자우선순위를 뒤로하였던 공통점이 이번 대규모 인명피해에 대한 직접 원인이라는 지적이 제시되고 있는 한편으로, 그동안 선진국을 중심으로 발전해 오던 지진해일 대책에 대한 취약점이 지적되면서 대책의 수정이 필요하게 되었다 경보체제의 정비를 뒤로하더라도, 주민의 방재의식과 재해에 대한 지식 함양을 지진해일재해에 대한 직접적 해결책으로 선진국들은 주장하고 있다. 본 고에서는 그 위력과 예측불허의 특성 때문에 지구상의 대재앙으로 여기는 지진해일에 대하여 우리가 처해 있는 위험환경과 대책마련에 있어서의 문제점에 대해 짚어 보고자 한다.

Recently seismic fragility analysis method has been widely used for the seismic probabilistic risk assessment of infrastructures such as nuclear power plants, buildings and bridges because of its probabilistic characteristics. Furthermore, this technique has been applied to large-scale social systems consisted of each infrastructures by combing GIS. In this paper, the applicability of this technique to domestic infrastructural systems was studied. The transportation network was selected as one of these domestic infrastructural systems. Example studies were peformed about Changwon city. Nonlinear time history analysis, with a maximal likelihood approach were conducted to establish the fragility curves of each infrastrucures (bridges). GIS analysis was also applied to the analysis of whole infrastructural systems. The results show that it is very useful to predict seismic probabilistic risk assessment of this domestic transportation network. However, it also shows that further studies such as more suitable damage criterion to domestic structure and precise nonlinear analysis techniques should be developed to predict more precise results.
