应变固体潮相位与地震关系的研究

STUDY ON THE RELATION OF STRAIN TIDAL PHASE AND EARTHQUAKES

  • 摘要: 经过计算华北地区的46次ML>5级地震震中位置发生时刻的固体潮相位, 发现华北地区的中强地震多数发生在固体潮的π/2或3π/2相位时段, 所占比例接近70%。充分显示该区在固体潮波上存在着两个发震概率较大的特殊相位。这种在应变固体潮最大或最小时段发震的现象, 说明尽管固体潮不一定是造成地震的内因, 但地震的发生明显受到日月引力作用, 尤其以华北北部燕山褶断带的地震最为突出。

     

    Abstract: after calculating the phases of Earth tide for the occurrence of 46 ML5 earthquakes in North China, we found near 70% of the earthquakes occurred in π/2 or 3π/2 phase of Earth tide.It indicates that there are two special phases in the Earth tide with high probability of earthquake.This phenomenon shows that the earthquake is affected by the gravity of the sun and the moon, especially in the northern part of North China, though it may not be the direct cause.
