日月引潮力与中国西北地区地震发震时间的深入研究

THE DEEP RESEARCH ON THE RELATIONSHIP BETWEEN THE LUNAR AND SOLAR TIDE-GENERATING FORCE AND THE OCCURRENCE TIME OF EARTHQUAKES IN THE NORTHWEST CHINA

摘要:

深入研究了中国西北地区的地震与日月引潮力的关系.通过仔细分析西北地区活动断裂带的特点,把引潮力的水平分量分解为平行及垂直于活动断裂带走向的两个分量,研究其与地震发震时间的关系.研究结果表明,两个水平分量与地震的发震时间密切相关,其中平行于断裂带走向的水平分量与地震发生时间的关系更为密切,对不同的活动断裂带,相关关系又有所不同,这可能与断裂带的构造特点有关.

Abstract:

In this paper, the relationship between seismicity in the Northwest China and three components of the Lunar and Solar tide-generating force has been researched deeply.Based on the geological structure in the region, authors let one of two horizontal components of the tidal force parallel to rupture strike and another perpendicular to that.The result shows that there is an important relationship between seismicity and two horizontal components simultaneously,and parallel one is more important than vertical one.This result has more important significance for predicting occurrence time of an earthquake.
