【摘要】 2007年甘肃测震台网记录到ML>3.0的地震43次,本文选取了其中17例,利用垂直向PG波初动波形进行了地震矩张量反演,给出了最佳双力偶解,并对一些地震发震背景和发震机理进行了分析讨论。对地震机理研究及未来地震预报提供了参考依据。更多还原

【Abstract】 In 2007,total 43 ML>3.0 earthquake were recorded in Gansu province. Among them 17 events are selected for focal mechanism inversion,using the method of seismic moment tensor inversion with P wave onset. The basic parameters of best double-couple are gotten. Based on the result,the earthquake tectonic backgrounds and mechanism in some areas of Gansu province are discussed. The result could afford reference to earthquake prediction in the region.更多还原
