Telesca I. Cheloidze T. Javakhishvili Zurab zurab_javakhishvili@iliauni.edu.ge Zhukova N. pub GPH Q ins3 public Frequency of earthquake occurrences in Caucasus is investigated on hourly and daily timescales. The observation period is 51 years, which is sufficiently long to perform a reliable statistics. Several methods (power spectrum, wavelet and Hilbert–Huang transformation) are applied to earthquake time series. Our findings show that earthquakes hourly and daily occurrence is not characterized by the dominant frequencies. However, many different oscillations with periods from hours to years and longer contribute to the frequency content of the earthquake time distribution, although their amplitude is rather low. The variation of the power of cyclic components in the temporal features of earthquakes occurrence is not uniform, but their amplification corresponds to the decrease of released local seismic energy. 2013-11 Tectonophysics 608 ELSEVIER 857-865 TRUE 0040-1951
