| 摘 要： | 利用江苏台网15个地震台的84个地震DD-1短周期记录资料,通过m_(Lg)震级与持续时间τ和震中距Δ相关,得出该区持续时间震级M_D公式:M_D=a_0+0.44(lgτ)~2+0.00036Δ+DM这里,a_0为与记录分向和尾波截止水平有关的常数;DM为台站校正值。M_D标度内部单台标准差为0.09～0.10震级单位,M_D相对m_(Lg)的单台标准差为0.16～0.17震级单位。

| Abstract: | The formula of duration time magnitude MD of Jisngsu seismic network consisted of 15 stations is obtained using data of records of 84 earthquakes of the network DD- 1 short period seismographs, and through correlation between mLg and duration time τand epicenter distance Δ,MD = a0+0. 44(lgr)2+0.00036Δ+ DM,where, a0 is constant associated with record component and cut-off level of coda, DM is calibrated value of station. The standard deviation of single station within MD scale is 0. 09-0. 10, that of single station of
MD relative to mLg is 0.16-0. 17. |
