金寨地震序列震源参数研究
Study On Seismic Source Parameters of Jinzhai Earthquake Sequence
摘要
Abstract
With the waveform data recorded by Anhui network,the paper does the seismic repositioning,further baseline correction,site response deduction,inelastic attenuation and so on.Based on above,the paper inverse and calculates source parameters of Jinzhai earthquake sequence in 2014,analyzes the changes feature and the relationship between the source parameters.The results show that:apparent stress,seismic moment and other source parameters changing over time showed enhanced front shock significantly weakening trend after the main shock,main shock reaches the maximum,while each parameter value reduced to a relatively low level,and stabilized after earthquake;apparent stress was significantly positively correlated with seismic moment and magnitude,while the increasing trend of stress drop is not obvious,comer frequency and seismic moment was a significant negative correlation,logarithm of seismic moment and magnitude linearly related,which has an important role in understanding the physical meaning of the source parameters.These results provide a scientific basis for earthquake determination and forecasting of Dabie Mountain and the surrounding area.关键词
