【摘要】 分析1970—2010年鄂尔多斯周缘发生的114次显著地震序列,结果表明,主余型序列占57%,孤立型序列占32%,多震型序列占11%。根据地震类型的空间分布特点,对鄂尔多斯周缘地震进行分区,各分区主余型地震占多数,多震型地震主要集中在鄂尔多斯北缘和东缘中北段,孤立型地震在鄂尔多斯西缘南段、南缘和东缘南段比例较高。更多还原

【Abstract】 114 earthquake sequences at the edge of Ordos block from 1970 to 2010 are analyzed.The results show that among the 114 earthquake sequences 57%is the mainshock-aftershock type,32%for the isolated type and 11%for multi-shock type.In the three types of earthquake, the mainshock-aftershock type presents even distribution,the isolated type accounts for a rather high percentage in the southwest edge,south edge and southeast edge of the bloc,the multi-shock type mostly occurred in the north edge and northeast edge of the block.更多还原
