- Abstract:
- Through spectrum analysis of observation recordings of Ludian MS6.5 earthquake in 2014 recorded by 13 strong motion station,we estimated the source parameters of the earthquake such as seismic moments,moment magnitude,corner frequency etc.and obtained the average moment magnitude MW=6.3.Then we discussed the influence of the displacement spectrum shape coefficients of the Brune source model and the local site condition on the source parameter estimation.The results show that the influence of the spectrum shape coefficients on the source parameter estimation is small,but source spectrum model ω2 and ω3 fit the source spectrums of recordings from far site and near-site separately.At the same time,only when the predominant site frequency is smaller than 1 Hz,the site condition could influence the source parameter estimation.The studied 13 stations are all located atⅠand Ⅱ sites,so the local site condition does not influence the results of the source parameter estimation.
