| Περίληψη: | The complex turbulent dynamics of seismogenesis in the area of Greece is investigated, applying an alternative approach based on the framework of renewal theory, namely the Renewal Aging Algorithm, to two earthquake interevent (waiting) time series. The data set was extracted from the regional earthquake catalogue compiled by the Geophysics Department of the Aristotle University of Thessaloniki and comprises a complete sample of 576 earthquakes with M≥5.5 occurred during 1911–2017 and 113 earthquakes of M≥6.5, in the period of 1845– 2017 (http://geophysics.geo.auth.gr/ss/station_index_en.html). This methodology is efficient for studying persistency and/or intermittent structures in different time scales of Hellenic seismogenesis by qualitatively estimating the amount of memory, corresponding to the ratio between Poisson and non-Poisson critical events. For the application of the Renewal Aging Algorithm time scales corresponding to short- and intermediate- term prediction were considered, namely 2-3 weeks up to 6 years. The results of the statistical analysis reveal transitions from time-homogeneous Poisson to time-homogeneous non-Poisson dynamics and non-homogeneous non-Poisson dynamics, starting from short time scales and considering longer time scales. These results can shed more light to the concept of the irregular seismic cycle hypothesis for the study area. It is worth to be mentioned that these time series are relatively short and therefore additional statistical analysis is required to verify the aforementioned findings. |
