“…On the other hand, several temporary seismological networks were installed in the broader area of the Gulf of Corinth since 1990. Some of them were installed to record background seismicity (EPOC Final Scientific Report 1995, Tiberi et al 2000, Papadimitriou et al 2001, while others to record the aftershock sequences of large events, as the 1992 Galaxidi (Kemezentzidou et al 1993) and the 1995 Aigion (Bernard et al 1997) earthquakes.

ΠερίληψηΟ Κορινθιακός κόλπος είναι μία ασύμμετρη τεκτονική τάφρος που οριοθετείται από ενεργά κανονικά ρήγματα και αποτελεί μία από τις περιοχές με τις μεγαλύτερες συγκεντρώσεις σεισμικών εστιών στον Ελληνικό χώρο. Η έλλειψη μόνιμων σεισμολογικών σταθμών στην περιοχή του Ανατολικού Κορινθιακού κόλπου οδήγησε στην εγκατάσταση του τηλεμετρικού δικτύου Cornet που έλαβε χώρα κατά το έτος 1995 και αποτελεί το μόνιμο δίκτυο του Τομέα Γεωφυσικής -Γεωθερμίας του Τμήματος Γεωλογίας και Γεωπεριβάλλοντος του Πανεπιστημίου Αθηνών. Καθορίστηκε ένα μοντέλο μέσων ταχυτήτων, αποτελούμενο από έξι σεισμικά στρώματα, στην περιοχή του Ανατολικού Κορινθιακού κόλπου, προκειμένου να επιτευχθεί ο καλύτερος δυνατός προσδιορισμός των υποκέντρων και των εστιακών παραμέτρων. Ο προσδιορισμός ενός αξιόπιστου σεισμικού μεγέθους αποτέλεσε τον κύριο στόχο της παρούσας εργασίας. Αναπτύχθηκε λογισμικό για τον υπολογισμό των σταθερών α, β και γ για τον υπολογισμό του μεγέθους διάρκειας M D . Ακολούθως, προσδιορίστηκε το μέγεθος σεισμικής ροπής M w , το οποίο θεωρείται το πλέον αξιόπιστο. Ο προσδιορισμός της σεισμικής ροπής Mo επετεύχθη μέσω φασματικής ανάλυσης. Μετά τον ανεξάρτητο προσδιορισμό του μεγέθους σεισμικής

“…The seismicity of the area includes 5 main earthquakes of magnitude greater than 5.8 since 1960. The last major earthquake was the 1995 Aigion earthquake (M s = 6.2, Bernard et al, 1997) and since then the seismic activity has been dominated by small-to medium-sized earthquakes.…”

Abstract. In the present work the statistical properties of the earthquake activity in a highly seismic region, the West Corinth rift (Central Greece), are being studied by means of generalized statistical physics. By using a dataset that covers the period 2001-2008, we investigate the earthquake energy distribution and the distribution of the time intervals (interevent times) between the successive events. As has been reported previously, these distributions exhibit complex statistical properties and fractality. By using detrended fluctuation analysis (DFA), a well-established method for detection of long-range correlations in non-stationary signals, it is shown that long-range correlations are also present in the earthquake activity. The existence of these properties motivates us to use non-extensive statistical physics (NESP) to investigate the statistical properties of the frequencymagnitude and the interevent time distributions, along with other well-known relations in seismology, such as the gamma distribution for interevent times. The results of the analysis indicate that the statistical properties of the earthquake activity can be successfully reproduced by means of NESP and that the earthquake activity at the West Corinth rift is correlated at all-time scales.

“…1) reveals a plethora of strong earthquakes since the preinstrumental era (Galanopoulos, 1936(Galanopoulos, , 1960Papazachos and Papazachou, 2003;Kouskouna and Makropoulos, 2004).This trend that also continued in the modern period of seismology, since 1900, has led to the occurrence of several large earthquakes (Mw ≥ 6.0, Makropoulos et al, 2012), such as the Galaxidi earthquake . One of the most well-known seismic events of the recent decades is the 15 June 1995 (Ms=6.2) Aigion earthquake (Bernard et al, 1997a). Since the occurrence of the Aigion event, the seismic energy in the Western GoC (WGoC) is mainly expressed by the generation of seismic swarms and not specific strong events (Lyon-Caen et al, 2004;Duverger et al, 2015;Kapetanidis et al, 2015).…”
