Inherent periodicities are observed in earthquake occurrence for three kinds of time series - one is based on a global earthquake occurrence record for the last two hundred years, while the others are based on either historical or recent Korean earthquake records. Above numerous minor peaks in the global earthquake occurrence spectra, there exist a few peaks including Chandler periodicity over 95 percent significance level. The global earthquake triggering mechanisms at each identified period are not entirely clear. An outstanding one-year periodicity has been found for the historical Korean earthquakes. This one-year periodicity is interpreted to reflect seasonal forcing that results in annual oscillation of Korean crust, as recorded over twelve years of GPS monitoring at Daejeon (DAEJ), one of International GNSS Service (IGS) permanent stations.
