Abstract We select Japan and its adjacent region as study areas,and divide it into some subareas.With the Schuster test we calculate the p-value of each subarea using tidal stresses caused by the sun and the moon.On this basis,the Schuster spectra are built for the subareas with p<5% in order to estimate the periodicity of seismicity in the subareas.Then,the correlation between seismicity and tidal stress in Japanis studied further.The results show that among the 75 subareas,the p-value of 22 subareas is less than 5%,and 2 of 22 subareas’ Schuster spectra show a distinct period of semidiurnal tides,which indicates the seismicity in these areas has a degree of triggering by tides.
