在单台速报工作中，准确确定震源深度与确定其他参数相比难度更大一些。本研究对太原地震台记录的斐济地区中源、深源地震事件进行了详细分析，总结了该区震相特征规律，以此特征规律用于分析该地区地震，可以较准确地确定震源深度。

It is difficult to ensure the deep of an earthquake relative to the else parameter when report the parameter of the just happened the earthquake in time. In this article, the authors analyzed the Fiji earthquakes, and summarized seismic wave characteristics of the deep earthquake on Fiji region recorded by Taiyuan Seismic Station. The characteristic rules presented here facilitate the determination of the depth of earthquakes in Fiji region.
