Ground motion attenuation relations of small and moderate earthquakes in Sichuan region-中国Betway体育网页登陆

摘要 Onthebasisof10935broadbandvelocityrecordsof135earthquakes(ML3.0-6.4andepicentraldistanceof26-623km)occurredfromMay12toJune10in2008,whicharecollectedfrom27bedrockstationsincludedinSichuanEarthquakeMonitoringNetwork,thecorrespondingaccelerationrecordsareobtainedbyareal-timesimulationmethod.Thenbyregressionanalysisonthedata,therelationbetweenthepeakgroundaccelerationandvelocityattenuationofsmallandmoderatebedrockearthquakesoccurredinSichuanregionisacquired.AndtherelationisverifiedbyaM4.8earthquaketookplacerecentlyinWenchuan.Finally,theattenuationrelations,whicharecoincidenttothegeologicalconditionsinSi-chuanregion,areproposedbystudyingtherecordsfromSichuanearthquakenetwork.
