| 基金项目： | Thanks are due the Backup Data Center of the China National Digital Seismograph Network for timing data service, and to Drs. Zheng Xiufen and Jiang Xudong for technical consultation about the instrumentation and observational data. The first author （Liu Chun ） is grateful for the help and cooperation of our colleagues in the Institute of Geophysics, CEA, during his work as a visiting scholar. |

| 摘 要： | Analyzing the aftershock sequence of the 2008 Wenchuan earthquake, we considered 26 microearthquakes ＂just underneath＂ seismic stations. Making use of such special station-event configurations to determine the depth of these micro-earthquakes provided accurate relocation of aftershocks with a reference set of ＂ground truth （GT） events＂.
