【摘要】 以中国地震台网(CSN)目录为标准,从2007年1月至2012年12月共计72个月的时间,选取了以巴塘地震台为中心,1~800 km范围内M L大于3.0级的地震共1 388个,按照地震的方位角进行统计分析。通过这些观测数据的处理分析,认为台西边(214度至329度)的地质结构是均匀介质,其它方位的地壳介质不是很均匀,比较复杂。更多还原

【Abstract】 Taking the earthquake catalogue of China Seismic Network as the reference,we select the earthquakes occurred within the radius range of 800 km and 1388 seismic events with the magnitude of greater than and equal to ML3. 0 to summarize the azimuth characters of seismic waves. Our statistical results suggest that the geological structure in the western region of the Batang Seismic Station within the azimuth range from 214 to 329 degree is uniform and the regions in the other azimuth ranges is not.更多还原
