地震情景在规划和协调应急响应、地震风险管理以及确定结构、生命线和公用设施的暴露方面发挥着重要作用。本文计算了1568年陕西高陵7级地震再次发生时可能产生的地面震动分布。为了调整地震动预报方程(GMPEs)以适应当地的实际情况,我们利用ShakeMap软件计算了1556年华县81/4级地震附近的一个场景,其中等震线的分布受历史记录的约束。我们使用的ASK 13 GMPEs,并发现,通过增加其标准偏差的50%,由此产生的地面震动,我们可以令人满意地再现历史观测。然后将该方案应用于1568年陕西高陵6 ~ 4级地震的情景ShakeMap计算。根据现场观测,确定了每种情况下孕震断层的破裂参数。根据Wald和艾伦[1]的地形坡度Vs 30模型计算了该地区的宏观地震场地条件。由此产生的场景ShakeMap为渭南市及其周边地区的地震危险性和风险计算提供了基础,这将在本期的其他部分进行描述。
Scenarios of earthquakes play an important role in planning and coordinating emergency response, seismic risk management, and identifying exposure of structures, lifelines, and utilities. We describe the calculation of distributions of ground shaking that might be generated if the 1568 Shaanxi Gaoling M~7 earthquake were to recur. In order to adjust the Ground Motion Prediction Equations (GMPEs) for the local conditions, we use the ShakeMap software to calculate a scenario of the nearby 1556 Huaxian M8¼ earthquake, for which the distribution of isoseismals is constrained by historical records. We use the ASK13 GMPEs, and find that, by augmenting the resulting ground shaking by 50% of its standard deviation, we can satisfactorily reproduce the historical observations. This scheme is then applied to the calculation of a scenario ShakeMap for the 1568 Shaanxi Gaoling M6¾ earthquake. The rupture parameters of the seismogenic faults for each of these scenarios are determined from field observations. The macroscopic seismic site conditions for this area are calculated from the topographic gradient Vs30 model of Wald and Allen [1]. The resultant scenario ShakeMap provides the basis for the calculations of seismic hazard and risk for Weinan city and its surroundings, which are described elsewhere in this issue.
