| 摘 要： | 本文整理了自2008年5月12日汶川8.0级地震至2010年4月14日玉树7.1级地震前,年度地震趋势预测和日常会商中提出的地震活动和前兆异常及其分析意见.结果表明,玉树7.1级地震前存在一些较为明确的有关地震活动水平和危险区域判定的预测依据,但由于玉树地区地震监测能力较弱,缺乏较为可靠的中短期前兆异常,因此未将该区划...

| Abstract: | In the paper,we collected and analyzed seismicity and precursor anomalies and their analysis results on yearly earthquake tendency forecast and weekly/monthly consultations between Wenchuan M8.0 earthquake on May 12,2008 and Yushu M7.1 earthquake on April 14,2010.The results show that there were some explicit phenomena before the Yushu M7.1 earthquake,which forecasted the earthquake tendency and important seismic risk area in China mainland.But Yushu is in an area of poor monitoring capability,lacking the c... |
