| 摘 要： | 应用甘东南流动台阵的微震资料进行定位方法研究,提出了基于全局网格搜索的t-D地震定位方法.应用该方法进行地震定位时,不需要建立速度模型,其定位结果与常规定位方法相比,震中位置基本一致,深度分辨率较高. |
| 关 键 词： | 台阵资料 地震定位 方法研究 |

| Abstract: | By the locating method study using the micro-seismic data of portable seismic array observation in the southeast area of Gansu province,a location approach of t-D based on global grid search is proposed.Earthquakes located by this method which do not need to set up velocity model,compared to conventional location method,their positioning are basically same in epicenter location,and have higher resolution in focal depth. |
