Abstract：Using the the108 seismic event waveform data recorded by Fujian regional digital seismic network and sharing data of seismic stations in the neighboring province during September 2012 to April,2015,the paper firstly used the Atkinson method to calculate the average crustal seismic wave attenuation in Fujian,and then used Moya method to obtain 98 station site response.On the basis of above,the paper calculated the source parameters of 45 earthquakes with ML ≥2.0 of the Fujian Xianyou ML 5.0 earthquake swarm sequence and calibrated the relations among the parameters.The results show that:in single logarithmic coordinates,seismic moment M0 increase with increasing magnitude ML,there is a good linear relationship as the statistical relationship for LogM0=1.06×ML+9.9;relationship between the focal radius and the earthquake magnitude is r=112.7×ML-152.8;comer frequency reduce with increasing magnitude ML,the linear relationship isf=-3.2× Mr+17.7;stress drop increase with increasing magnitude ML,the linear relationship is Aσ=1.52×ML-3.28.
