| Abstract: | Based on the DK-1 medium long period records of Nanjing Seismological Station, the attenuation relation of surface wave coda is obtained with double amplitude A and back moving time τ , and M SC =0 88lg A H+1.51lg τ H+0.73=0.86lg A Z+1.47lg τ Z+0.76 is defined based on M S(PEK)magnitude scale. The M SC accuracy is improved with the multiple point measure of coda, its standard deviation is 0 12. |
