| 摘 要： | 紫坪铺水库微震台网已经运行逾6年,强震台网已经运行逾3年,水库蓄水逾4年。2006年10月水磨突发ML1.4级微小地震群,库区及附近和库坝区地震活跃,依据监测研究较准确预测了2006年11月至2007年2月的水磨ML2.5级地震群。研究认为ML2.5级地震群是蓄水初期诱发的一些浅表卸荷型或岩溶塌陷型小地震。2008年5月12日汶川8级特大天然地震发生在微震台网监测范围内,水库微震台网和强震台阵的运行正常,为政府抗震救灾有效决策提供了科学依据,为稳定社会发挥了作用。

| Abstract: | The micro-earthquake monitoring network of the Zipingpu Dam has operated for six years and the strong-earthquake monitoring network has operated for three years as well.The time of dam filling is over four years.During the October 2006 a group of small earthquakes in the range ML=1.4 occurred around the area of the Zipingpu Dam.So it can be considered as the beginning of an earthquake active period.According to this consideration we predicted the happening of Shuimuo ML2.5 earthquake swarms from November 20... |
