A test of the cyclicity of earthquakes

The periodogram analysis of time intervals between successive earthquakes is used for testing the seismic gap hypothesis. Using the available data, it is shown that the existence of a periodic component can be rejected with high confidence. The test provides evidence against quasi-periodicity and re...

Zusammenfassung:	The periodogram analysis of time intervals between successive earthquakes is used for testing the seismic gap hypothesis. Using the available data, it is shown that the existence of a periodic component can be rejected with high confidence. The test provides evidence against quasi-periodicity and regular clustering of the arrival times.
