本文研究了发生在华北的四次强地震(即邢台、渤海、海城和唐山地震)与大气压力之间的相互关系,发现在空间和时间上,四次地震的气压变化型式几乎相似。1.震前震中地区的月平均气压距平位明显的不同于周围地区,震中十分靠近气压距平中心。2.震前逐日平均气压值呈现出一种超过10毫巴的特殊变化。上述现象表明地震孕育过程对大气可能有影响,也表明大气压力触发作用存在。作者认为这些结果可以用于短期预报。
This paper studies the correlation between the four strong earthquakes (ie, the Xingtai, Bohai, Haicheng and Tangshan earthquakes) and atmospheric pressure in North China and finds that the types of pressure changes in the four earthquakes are nearly similar in space and time. 1. Before the earthquake epicenter area of the monthly average pressure anomaly significantly different from the surrounding area, the epicenter is very close to the pressure anomaly center. 2. The average daily pressure before the earthquake showed a special change of more than 10 mbar. The above phenomena indicate that the earthquake breeding process may have an impact on the atmosphere and also indicate that atmospheric pressure triggering exists. The authors believe these results can be used for short-term forecasts.
