摘要
分析了潮汐形变观测记录的14个震例中36个前驱波图像的特点、形态、量级，总结了潮汐形变前驱波的时空特征：主震震级Ms≥5．9时出现的可能性大，出现的时间多为震前0．1-6．5天；台站对Ms=5、6、7、≥7．9地震的有效监测距离分别为70、300、400、2000km。
The feature, shapes and magnitudes of the 36 precursors of 14 earthquakes recorded by tidal deformation observation were analyzed. The space-time characteristics of tidal deformation precursors anomalies were summarlzed：the precursors may appear mostly before 0.1-6.5 days of Ms≥5.9 earthquake occuring,the effective monitoring distance for Ms=5,6,7 and ≥17.9 earthquake is about 70, 300, 400 and 2 000 km respectively.
