【摘要】 街面水库位于政和—大埔深断裂带东侧的屏南～梅林断陷带中段上。该深断裂带没列为地震带，活动性较弱，尤其是中段。街面水库以坝址为中心２５ｋｍ范围内，无喜山期的基性岩分布，无震中分布，近代地壳垂直形变值甚小，地热异常值不高，岩性于应变能的大量积储也不甚有利，与水口水库诱震条件类比认为：街面水库蓄水后，即使发生诱发地震，其强度也仅属弱微震，最大震级应比水口低，估计不会超过４级。可能震中位置在库盆东南面有断层切割的熔岩区段。更多还原

【Abstract】 Jiemian reservoir lies in the middle part of Pingnan￣Meilin fault depression zone to the east of Zhenghe￣Dapu deep fault zone,which is not classified as seismic belt,with a weak seismic activity,especially in the middle part.Within the range of 25 kilometers around the dam site,there is no Hiamalyan basic rock and epicenter distribution,the vertical deformation of the recent earth crust is insignificant,the anomaly value of terrestrial heat is not high,and the lithologic character is not favorable for the large scale storage of strain energy.By analogy with Jiemian reservoir impoundment,the earthquake magnitude would be of weak and micro tremor,with the maximum magnitude estimated at below 4 degree,lower than that observed in Shuikou reservoir area.The possible location of epicenter probably lies in the fault dissected lava area,in the south east to the reservoir.更多还原
