Astronomical Tides and Earthquakes

Wu Xiaoping, Mao Wei, Huang Yong (Earth Science Department, Yunnan University, Kunming 650091) (Yunnan Observatory Chinese Academy of Sciences, Kunming 650011) (Seisznological Bureau of Yunnan Province, Kunming 650041)  
A review on the studies of correlation between astronomical tides and earthquakes is given in three categories, including (1) earthquakes and the relative locations of the sun, the moon and the earth, (2) earthquakes and the periods and phases of tides and (3) earthquakes and the tidal stress. The first two categories mainly investigate whether or not there exist any dominant pattern of the relative locations of the sun, the moon and the earth during earthquakes, whether or not the occurrences of earthquakes are clustered in any special phase during a tidal period, whether or not there exists any tidal periodic phenomenon in seismic activities. By emphasizing the tidal stress in seismic focus, the third category investigates the relationship between various seismic faults and the triggering effects of tidal stress, which reaches the crux of the issue. Possible reasons to various inconsistent investigation results by using various methods and samples are analyzed and further investigations are proposed.
