东江水库自蓄水前约半年起就开始进行地震监测，发震后通过密集台网强化观测、震源机制解及地震地质等多项工作，综合研究该库诱发地震发震原因，认为由于库水渗透引起的多种局部性应力调整导致水库诱发地震活动．其发展趋势将表现为逐渐衰减，今后不致于发生破坏性地震． Dongjiang Reservoir began to monitor the earthquakes about six months before the impoundment. After intensive earth-grid strengthening observation, focal mechanism solution and seismic geology, etc., after the earthquake, a comprehensive study was conducted on the causes of the seismogenic earthquake induced by this reservoir. Various localized stress adjustments caused by infiltration lead to reservoir-induced seismicity. Its development trend will show a gradual decline, the future will not be devastating earthquake.
