【摘要】 利用2000年至2008年苏中沿海地区射阳地震台和海安地震台记录到的100km范围内ML2.0以上地震波形资料,基于Sato模型,采用不同的固定流逝时间,计算了该区域的尾波Qc值。结果表明:该区为尾波Qc值低值区域,随着流逝时间的增大尾波Qc值也变大;在2006年11月份东台ML4.1震群和2007年5月6日响水ML4.0地震前尾波Q0值有明显增大现象。更多还原

【Abstract】 Based on the scatter model(Sato),using earthquake wave form data with ML≥ 2.0 from 2000 to 2008 recorded by Sheyang and Hai’an seismic stations in the coastal areas of central Jiangsu province,the Qc values of coda with different lapse time in this region is calculated.The result indicates that this region has low Qc value,and the Qc values increase with lapse time increasing.Before Dongtai ML4.1 earthquake swarm in November,2006 and Xiangshui ML4.0 earthquake on May 6,2007,the Qc values of coda increased apparently.更多还原
