Three new scientific research finding and progress on decadal-scale correlation between crustal deformation and length of day, silent earthquake and precursory wave have been briefly introduced in this paper, and their implications to prem onitory anomaly and earthquake prediction are also analyzed. Tentative researche s demonstrate that: core-mantle coupling induced fluctuations in crustal deform ation, geophysical observations, are important modulations to back-ground anoma ly variations on years to decade-time scales; Slow rupture process within the t ransition zone of fault is an important source for short-term premonitory anoma lies on days to months time scales; The low-frequency precursory waves (slow ea rthquake waves) originating from transition zone or weaken brittle part of fault are repeatable and reliable imminent precursors, which generally come out sever al hours to seven days before strong earthquakes.
