攀枝花仁和区—凉山州会理县6.1级地震跟踪预测回顾
|
摘要
以震前会商记录和震情跟踪研讨资料为主,回顾了2008年8月30日攀枝花仁和—凉山州会理间6.1级地震前的短期异常和跟踪预测情况。结果表明:2008年8月30日仁和—会理6.1级地震前川滇交界的布拖、普格、宁南一带存在小震群活动异常;理塘至川滇交界的西昌和攀枝花一带存在地下流体、形变及电磁等多项短期前兆异常;有的防震减灾部门在震前提出了短期分析预测意见。
Base on records of consulted meeting and data of seismic regime tracing deliberation,the short-terms abnormity and tracing forecast before Panzhihua Renhe-Liangshan Huili Ms6. 1 earthquake on August 30,2008,is reviewed. The result indicated that there were abnormal activity of small earthquake swarms taken place in the counties of Butuo,Puge,Ningnan,the border areas between Sichuan and Yunnan provinces and there were multi-and short-terms precursor abnormity such as the underground fluid,the deformation and the electromagnetism from Litang to Xichang and Panzhihua in border area between Sichuan and Yunnan provinces. Some of the seismic department of local government gave the short-term analysis forecast comment before shaking.
