１９９７年９月广东省三水市发生的ＭＬ３７、４４级地震因震中烈度比同等震级的其它震例偏高许多，而且多个台站均记录到长周期振动规则的正弦形面波而特别引人注目。精确测定了这组地震的震源位置，得到震源深度约等于１ｋｍ；对比分析了震相记录特征、震区周围的历史地震活动及地质构造背景，认为这是一组罕见的低震级高烈度震例，其发生可能与震中附近的Ｆ７断层活动有关。 In September 1997, the ML37,444 earthquakes occurred in Sanshui, Guangdong Province, due to the fact that the epicentral intensity was much higher than other earthquakes of the same magnitude, and many stations recorded the sine surface of long-period vibrational rules Waves are particularly noticeable. The hypocenter depth of this group of earthquakes is estimated to be approximately 1 km. The characteristics of seismic facies records, historical seismic activities around the earthquake area and geological tectonic setting are comparatively analyzed. It is considered that this is a rare case of earthquake with low magnitude and high intensity , Which may be related to the F7 fault activity near the epicenter.
