摘要
基于云南地区烈度衰减模型、人员伤亡、经济损失、次生灾害等评估模型,在云南鲁甸6.5级地震发生后30 min内,云南地震灾害应急指挥中心启动云南地震应急快速评估系统快速产出地震灾害损失预评估结果,震后4 h内,根据获取的灾情信息,综合考虑地震震级、发震时间、震区人口密度、房屋抗震性能、自然地理环境、地质构造条件、历史地震震害特征等因素,结合专家经验,对预评估结果进行了修正并上报各级部门,为鲁甸地震应急指挥决策、灾害损失评估、政府指导抗震救灾工作提供了基础信息服务。
Within 30 minutes after the Ludian MS6.5 earthquake,the pre-evaluation results of earthquake disaster loss was output rapidly by Yunnan Seismic Rapid Assessment System developed by Yunnan Earthquake Emergency Command Centre based on the establishment of the earthquake assessment models of intensity attenuation,casualties,economic losses and secondary disaster etc.in Yunnan area.Within 4 hours after the earthquake,according to the obtained disaster information,considering the earthquake magnitude pccurrence time,and the population density,housing seismic performance,natural and geographical environment,geological conditions/historical earthquake damage characteristics etc.in disaster zone,combined with expert experience,the pre-assessment results were made a correction and reported to the departments at all levels.These reports could provide basic information services for the decision making about earthquake emergency command,disaster loss assessment,and government guidance for earthquake relief work of Ludian earthquake.
