尾波Q(下標 c)值隨時間變化在地震預測中應用的研究
2005
The coda-wave attenuation quality factor Q(subscript c), values in the periphery areas of seismic stations in Yunnan Province were estimated using the single-scattering attenuation model of Sato from 1403 local seismic events recorded by a regional network of 22 digital stations from the latter half of 1999 to the latter half of 2004. And temporal changes of coda Q(subscript c), of 14 stations with relative richer data were given out. Based on the temporal changes of average coda Q(subscript c), at 3 Hz, 10 Hz, and 18 Hz at these 14 stations around January 1, 2002, the risky areas were predicted in the vicinity of the southeastern boundary and the southwestern as well as the western boundary of Dianzhong Active-tectonic Block.
