摘要/Abstract

摘要： 运用QSGRN/QSCMP理论地震图计算与合成方法，根据震源机制解设定断层几何参数，模拟了2016年11月25日阿克陶6.7级地震周边区域加速度记录，经场地条件校正绘制了地震峰值加速度分布图。通过对2个强震台观测波形数据与模拟加速度波形数据在时间域和频率域进行对比分析，验证了两者振幅数量级相当、频谱特征一致性较强。同时，提取了实际调查点坐标所对应的模拟峰值加速度，并与实际调查点烈度进行对比，发现两者具有较好的对应关系。文中尝试提供1种震后快速产出峰值加速度分布情况的方法，为监测台站稀少、地形复杂、难以快速开展现场地震灾害调查的地区提供地震影响场范围估计，为地震灾害快速评估与应急决策等工作提供辅助资料。

Abstract: Aketao M6.7 earthquake on November 25, 2016 occurred in Aketao Country, Kizilsu Kirghiz Autonomous Prefecture, Xinjiang Autonomous Region. In this paper, according to the focal mechanism solution, the geometrical parameters of the fault are used as input to simulate the acceleration records of the surrounding area of Aketao M6.7 earthquake on November 25, 2016 with the QSGRN/QSCMP program. The peak ground acceleration distribution is plotted by extracted peak ground accelerations and site condition correction. Comparison is carried out between the observed waveforms and the simulated waveforms in the time domain and the frequency domain of two strong motion stations. It is verified that the amplitudes of simulated and observed data are equal in magnitude, their calculated residuals are smaller in low frequency range and the spectral characteristics of simulated and observed data are consistent. Furthermore, the simulated peak ground acceleration corresponding to the coordinates of the actual survey points is extracted and compared with the survey spot intensity, and both have good correspondence. This paper attempts to provide a method for rapid output of peak ground acceleration distribution after an earthquake, so as to provide a method for estimating the seismic impact field in areas where the monitoring station is scarce, the topography is complex or it is difficult to implement the rapid earthquake disaster investigation. And it also provides supporting information for rapid assessment of earthquake disaster and emergency decision-making.

Key words: Aketao M6.7 earthquake, theoretical Green's function, peak ground acceleration, survey spot intensity
