江苏台网尾波持续时间震级的初步研究
PRELIMINARY STUDY OF COAD DURATION TIME MAGNITUDE OF JIANGSU NETWORK
【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mLg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MD公式:MD=a0+0.44(lgτ)2+0.00036Δ+DM这里,a0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。MD标度内部单台标准差为0.09~0.10震级单位,MD相对mLg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 ofMD relative to mLg is 0.16-0. 17.
