| 摘 要： | 渭河盆地是环鄂尔多斯地块周缘大型断陷盆地之一。在环鄂尔多斯地块的4个边中,渭河盆地的现代地震活动属于最弱的一边,表现为环鄂尔多斯地块最大的地震空段。渭河盆地内部由多个次级断块组成,但它们对盆地内的现代地震活动控制却不明显。作为青藏高原东北缘紧邻的一个大型外侧盆地,盆地内的现代地震活动与青藏高原的大震活动存在着一定的响应,表现为伴随着青藏高原的大震活动,盆地内部的地震活动也明显增强。

| Abstract: | Weihe Basin is one of the marginal graben basins around the Ordos,Northern China. Around the Ordos block,Weihe basin is the weakest modern earthquake activities and it is the largest earthquake gap.There＇re several secondary blocks in Weihe basin,however,they can＇t obviously control the modern seimicity. As a large basin adjoining to northeastern margin of Qinghai-Tibetan plateau,the modern earthquake activities in Weihe basin may be responsed to those in Qinghai-Tibetan plateau,the earthquake activities increase in Weihe basin with the status of Qinghai-Tibetan plateau. |
