地震灾害风险是指破坏性地震(Ms≥4.7)对生命财产和经济活动造成的风险期望值。在搜集辽东半岛地震地质和震害史料的基础上,采用GIS空间分析技术和数理统计方法,从地震危险性和承灾体脆弱性两个角度,从地震强度,地震频率,人口,经济暴露性,断裂带敏感性等5项指标,对辽东半岛地震灾害风险进行了综合评估。结果表明,辽东半岛地震灾害高风险区主要集中在海城-大石桥、丹东-东港、普兰店-金州3个区域。
Earthquake disaster risk refers to the destructive earthquake (Ms ≥ 4.7), the life expectancy and financial activities caused by the expected value. Based on the collection of historical data of seismic geology and seismic damage in Liaodong Peninsula, GIS spatial analysis technique and mathematical statistics method are used to analyze seismic intensity, seismic frequency, population, economic exposure , The sensitivity of the fault zone and other five indicators, a comprehensive assessment of the risk of earthquake disasters in the Liaodong Peninsula. The results show that the high risk areas of the earthquake in Liaodong Peninsula are mainly concentrated in Haicheng - Dashiqiao, Dandong - Donggang, Pulandian - Jinzhou.
