| 摘 要： | 对佛子岭地震台50km范围内1980-2008年13000余条弱震记录进行了统计分析，发现大部分3级以上（为本地区相对较大）的地震震前PG波都有初动符号优势分布的特点。根据本台弱震记录是否出现初动符号优势分布，对判别本地区未来可能发生较大的地震会有所帮助。

| Abstract: | Base on the statistical analysis of more than 13 000 weak earthquake records from 1980- 2008 in 50 km around Foziling Seismic Station, we found that the initial motion of PG wave appeared dominant distribution in the most of ML≥3. 0 earthquakes（which were relatively larger in local area）. It is helpful to distinguish the possible future larger earthquake in this region by reference whether the dominant distribution of initial motion appeared in weak earthquake recorded at single seismic station. |
