摘要:: 介绍了记录到的2007年6月3日宁洱6.4级地震较大主震加速度并且位于Ⅵ度及其以上烈度区内或附近的4个观测台强震动记录的各项参数、地震地质构造背景及地震活动、现场震害调查方法及结果,确定了本次地震的烈度,并将其与按照最大峰值加速度确定的烈度做对比。最后分析了这4个强震台的记录与实际现场调查的烈度的差异,探讨了产生差异的原因。

Abstract:: Four strong motion record stations had been located in Ⅵ degrees above seismic intensity zone or the nearby on June 3,2007 Ning'er M_S6.4 earthquake struck area.We recorded larger main-earthquake acceleration recordd by them.The paper describes seismogenic and seismicity at the venue of four strong motion record stations.We introduced the parameters of the strong motion records.We described investigation methods and results of earthquake disaster for the four fields,and determined the seismic intensity,and compared with seismic intensity by the maximum peak acceleration in accordance.We analyzed differences of seismic intensity between four strong motion records and actual scene investigation records.We discussed reasons of differences for seismic intensity too.
