摘要:
基于2021年云南漾濞MS6.4主震预警台网地震动数据,使用多种空间插值方法探讨获得最优仪器地震烈度影响场,并与宏观地震烈度调查结果进行对比分析。结果表明:基于指数模型变异函数的普通克里金插值法获得的仪器地震烈度影响场与宏观地震烈度具有较好的一致性,能够反映实际地震烈度空间总体影响场范围及特征; 除了两者因概念和属性不同而造成的影响场差异之外,台站分布、场地条件、空间插值方法、前震和余震震害叠加等因素也是导致本次地震影响场差异的主要原因。
Abstract:
Based on the ground motion data of the Yangbi MS6.4 earthquake recorded by the Yunnan Early Warning Network,a variety of spatial interpolation methods are used to obtain the optimal instrumental intensity influence field,and compared with the results from the macroscopic intensity obtained from field survey.The results show that the influence field of instrumental intensity obtained by the ordinary Kriging interpolation method based on the variogram of the exponential model has a good agreement with the macroscopic seismic intensity,which can reflect the overall range of the influence field and characteristics of the actual seismic intensity.The main reasons for the differences between the instrumental intensity influence field and the macroscopic intensity field are the distribution of stations,site conditions,spatial interpolation methods,and the superposition of foreshocks' damage and aftershocks' damage.
