我国大陆板内地震活动与周边板间地震活动关系的探讨

RESEARCH ON RELATION OF SEISMIC ACTIVITIES IN WEST CHINA AND NEIGHBORING REGIONS

探讨了周缘板块对我国大陆西部地区地震的影响 ,并对不同构造带上地震的时空分布特征、相互关系等进行了分析。结果表明我国大陆西部及周缘地区的地震发生有高潮和低潮的轮回特征 ,同时释放的能量有相互消长的关系 。

China mainland lies in the southeast of Eurasia plate, compressed by its neighboring plates, the seismic activity is frequent. By analyzing the influence that the neighboring plates on West China, the time and space distribution characteristics of the earthquakes in various tectonic belts and their relation, it is indicated that in West China and its neighboring regions, the peak and valley of the seismicity take turns occurring; the seismic energy releasing alternately grows and declines between the collision zone of India plate and Eurasia plate and the influence region of the collision zone, which obeys a certain ratio.
