气象变化与邢台地震关系初探
PRELIMINARY STUDY ON RELATIONS BETWEEN METEROLOGICAL VARIATION AND XINGTAI EARTHQUAKES
【摘要】 本文对邢台地震活动与气象的关系进行了分析研究,认为邢台除1966年3月大震前有明显的气象异常,大震后的中强余震前亦有气象异常。此外,还发现低气压对强震,余震活动均有显著影响。经分析,我们认为低气压天气过程对地震活动有不可忽略的触发作用。
【Abstract】 Relations between Xingtai earthquake and meterology have been studied in this paper. It is considered that besides meterological anomalies before Xingtai major earthquake in March 1966 there also exist weather anomalies before moderate - strong aftershocks. In addition, it is found that low atmospheric pressure has distinct influence to strong earthqkes and aftershocks. Through analyses the authors consider that werther process with low atmospheric pressure has triggering function to seismic activity which can not be neglected.
