论地方地震工作在短临预报中的作用

ON THE APPLICATION OF LOCAL SEISMIC WORK IN SHORT—TERM AND IMMINENT EARTHQUAKE PREDICTION

地方地震工作是我国地震工作的重要组成部分,在短临预报的监测、震情的动态跟踪、前兆观测方法的探索以及各种前兆信息的获取和识别方面。具有与专业地震队伍不同的特点、优势和不可替代的作用。地方地震工作还具有观测手段比较科学,布局比较合理,覆盖面广,接近震区,可补充专业台网不足等特点,因此已经成为整个地震系统中捕捉短临异常、实施短临预报不可缺少的一个重要组成部分。同专业地震队伍一起密切配合,为综合防御和最大程度减轻地震灾害发挥了重要作用。

Local seismic work is an important part of the seismic work in China, it has different characteristics and advantages compared with the special seismic ranks and its nction could not be replaced by the special ranks in short-term and imminent prediction, tracing to the dynamic state of seismic situation, the study of precursory observation methods and obtaining and identifying various precursory information. The observation means used in local seismic work are of relatively scientific, with relatively reasonable arrangement, covering vast area and close to seismic regions which can complement inadequacy of the observational networks managed by the special seismic ranks, so it has become an important part of the whole seismic system in catching short-term and imminent anomalies and in implementing short—term and imminent predictoin. With close cooperation to the special seismic ranks, the local seismic work has played an important role in comprehensive defence and seismic hazard reduction.
