EFFECTS OF SOURCE PROPERTIES ON CUTOFF FREQUENCY f_(max)

郑天愉  姚振兴  
【摘要】:正 The cutoff frequency f_(max) of radiation from earthquakes is one of the important parameters for studying the source process. By theoretical analysis and numerical experiments on acceleration Fourier spectrum it is suggested that f_(max) mainly depends on the lower values of slip rise time. This result can be used to explain the observational fact that the greater the earthquake magnitude, the smaller the value of f_(max).
