Outline
Utilizing the Yunnan small earthquake monthly catalog and seismic wave data recorded by the seismic network, we calculated the correlation coefficients of spectral amplitudes for Yunnan M≥5.0 earthquake sequences since 2008. A comprehensive analysis of traditional seismological parameters, including the h and b values, for different types of earthquake sequences revealed that the correlation coefficients of spectral amplitudes for foreshock type seismic sequences are significantly higher than those for earthquake swarm and mainshock-aftershock type sequences. Moreover, the range of variation is relatively small, with values exhibiting a concentrated distribution. In contrast, traditional seismological parameters show a more concentrated b value and a wider distribution range for the h value. Analysis of the correlation coefficients of spectral amplitudes for 8 typical foreshock type earthquake sequences indicates a good correspondence between changes in the correlation coefficients of spectral amplitude and the magnitude intensity of foreshock type earthquake sequences. The analysis suggests that a high correlation coefficient of spectral amplitude is indicative of high regional stress levels, and fluctuations in the correlation coefficient of spectral amplitude may be influenced by the loading and unloading of seismic stress.
