Risk Analysis of Earthquake Disasters in Shandong and Coastal Areas and Its Preliminary strategies

Abstract

Shandong and its coastal areas are located in the eastern part of the North China tectonic region, and their strong seismic activities are uneven. There have been devastating earthquakes such as the Tanlu earthquake, the Bohai earthquake, and the Heze earthquake in history. With the development of the economy and the dramatic increase in population density, the earthquake disaster risk in Shandong and coastal areas has become increasingly high. This paper focuses on the characteristics of earthquake hazard analysis and earthquake disaster risk in Shandong and coastal areas, introduces population density and GDP development level of Shandong area into the disaster carrier, and then obtains the spatial distribution of earthquake disater risk in Shandong province. At last, according to the characteristics of earthquake disaster risk in Shandong, some suggestions to reduce earthquake disaster risk are given. Keywords—Earthquake Hazard Analysis; Earthquake Disaster Risk Analysis; Disaster carrier; Shandong and its coastal areas; preliminary strategies 摘要:山东及其沿海地区位于华北构造区东 部,其强震活动具有不均匀性。历史上发生 过郯庐大地震、渤海地震、菏泽大地震等破 坏性地震,随着经济的发展和人口密度的剧 增,山东及沿海地区的地震灾害风险逐渐增 高,本文重点研究了山东及沿海区域的地震 危险性以及地震灾害风险的特征,将山东地 区的人口密度及 GDP发展水平等因素引入到 灾害的承载体中,进而得到了山东地区的地 震灾害风险的空间分布情况。最后根据山东 地区的地震灾害风险特征,给出了减轻地震 灾害风险的若干建议。 关键词:地震危险性分析,地震灾害风 险分析,灾害承灾体,山东及沿海区域,初 步对策
