| 摘 要： | 对１９９７年伽师强震群前后的近场宁点形变资料和卡尔曼滤波结果的前兆异常进行了分析,结果表明,震前短临异常较为明显。通过密切跟踪,在后续强震的预报中发挥了重要作用。文中还对异常与孕震构造和应力场的关系进行了讨论。

| Abstract: | Precursor
anomalies of near field crustal deformation data in fixed point and their Krlman filter
residual before and after the Jiashi strong earthquake swarm occurred in 1997 are
analyzed.It is concluded that short-impending anomalies play an important part in the
prediction of following strong earthquake through close follow the tracks of anomalous
variation.Finally,the relation between the anomaly and seismogenic structure and stress
field is discussed. |
