朔望月期间地月系统质量中心的重新定位在地壳中产生压力稀疏波。在Altai-Sayan,Kamchatka和Sakhalin地震活跃区的地震监测(包括地震波、天然电磁脉冲和氡放射)过程中,记录到由于地月系统重新定位引起的长周期(14~15天)重力潮和变形波共振;得到了重力潮共振是强震(M≥5.0)触发机制的认识;并且,在80%的情况下产生单一的低速(1~5km/h)变形波(如孤立波)。研究结果表明,可以将重力潮共振用于地震预测、大型水利设施地球动力学灾害预警和油气藏的直接勘探。
Reorientation of Earth-Moon system mass centers during the lunar new moon creates a pressure sparse wave in the crust. During the seismic monitoring (including seismic waves, natural electromagnetic pulses and radon emissions) of the active seismic zones of Altai-Sayan, Kamchatka and Sakhalin, long-period (14-15 days) gravity tides and deformations due to the relocation of the Earth-Moon system were recorded Wave resonances. It is known that the gravity wave resonance is the trigger mechanism of strong earthquakes (M≥5.0), and a single low-velocity (1-5 km / h) deformation wave (such as solitary wave) is generated in 80% of cases. The results show that gravity tide resonance can be used for earthquake prediction, warning of geodynamic hazard of large water conservancy facilities and direct exploration of oil and gas reservoirs.
