摘要
利用哈尔滨区域数字遥测台网记录的林甸地震序列资料,进行波谱分析及震源参数估算,并对该区的地震破裂模式作了初步的分析。利用上述结果,建立了地震矩M_0与震级M_L的关系式,以便利用震级M_L来估算矩震级M_w。
Based on the data of Lindian earthquake sequence recorded by Harbin regional digital telemetry network, the spectral analysis and the estimation of seismic parameters are carried out, and the mode of earthquake rupture in this area is analyzed prelimi- narily. Using the above results, a relational expression between the moment M0 and the magnitude ML is established to estimate the mo- ment magnitude Mw using the magnitude ML.
