摘要
2000年1月15日云南姚安发生了6．5级地震．震后围绕震中区架设了一个由6套拾震器-记录仪组成的临时数字地震台网．在所记录的余震中，有402次余震有较精确的定位．依照Sato的单散射模型分析观测的尾波短记录，获得了姚安地区地壳的尾波平均品质因子Qc(f)=49f^0.95，f=1．5～20．0Hz，具有高构造活动性区域的衰减特征．
An earthquake with M=6.5 happened on January 15, 2000 in Yao′an of Yunnan P rovince. After the earthquake, a temporary digital network with 6 detectors arou nd the epicenter area was set up. 402 aftershocks were located more precisely. A ccording to coda shorting recording observed by Sato single scattering model ana lyses, the coda averaging quality factor has been acquired, Q c(f)=49 f 0.95 , f=1.5～20.0 Hz, which has the attenuation characteristics of high tectonic structural active region.
