采用MSDP软件中LOCSAT和HYPOSAT定位方法,从震源偏差、残差分布方面对2007年7月吉林测震台网正式运行以来记录到的20次东北地区mb(mB)≥4.0深源地震资料进行对比分析。结果显示,对于东北深源地震HYPOSAT定位结果要优于LOCSAT定位结果。
20 mb(mB)≥4.0 deep-source earthquakes, recorded after July 2007 when Jilin Seismic Network was set up,are located respectively by LOCSAT and HYPOSAT of MSDP system.Then the results such as earthquakes’ epicenter and residual distribution.It shows that HYPSAT locating method should be adopted preferenctially to locating deep-source earthquakes in North-east China than LOCSAT.
