ANALYSIS TO THE EFFECT OF SEISMOLOGICAL OBSERVATIONAL ERROR ON SEISMOLOGICAL PARAMETERS

An artificial random disturbance is carried out for some seismological observation data in the allowance range of seismological observational error with random disturbance method.On the basis of this,the deviations of the 6 parameters(b value,η value,S value for degree of seismicity,H value for seismicity scale,equivalent earthquake M and frequency N)are analyzed with the data before and after the disturbance,in order to find out the effect of seismological observational error on seismological parameters.
