渤海地震的震源参数ht
SOURCE PARAMETERS OF THE BOHAI EARTHQUAKE OF 1969
-
摘要: 本文对20个WWSSN台记录到的渤海地震(1969年7月18日,MS=7.4)远震P波波形与理论地震图进行了对比。确定了渤海地震的震源参数为:地震矩2.6 1019Nm;震源破裂持续时间为12S;震源深度为35 km;两个节面为:(1)走向=24,倾角=85,错滑角=170;(2)=115,=80,=5。Abstract: We matched teleseismic P waveforms of the Bohai earthquake (July 18, 1969, Ms 7.4) recorded at 20 WWSSN stations with synthetic seismograms. The following source parameters are obtained: seismic moment M0 = 2.61019Nm; duration of source rupture 12s; depth H = 35km. The two nodle planes are (1) strike angle =24, dip angle = 85, rake angle = 170; (2) = 115, = 80 and = 5.
