Περίληψη

Η παρούσα πτυχιακή εργασία αποτελεί μια προσπάθεια συγκέντρωσης πληροφοριών για τα σημαντικότερα ρήγματα στην Βόρεια Ελλάδα, καθώς και τη μελέτη της σεισμικότητας της περιοχής. Παράλληλα, γίνεται μια αναδρομή σε ιστορικούς σεισμούς που έγιναν στην περιοχή μελέτης και τις επιπτώσεις που είχαν στο φυσικό και ανθρωπογενές περιβάλλον. Διερευνάται η πληρότητα των καταλόγων σεισμών που χρησιμοποιήθηκαν στην εργασία με την μέθοδο Goodness-of-Fit Test (GFT) για δύο διαφορετικές περιόδους, οι οποίες είναι από το 2008-2019 και από το 1911-2014, ενώ μελετάται η χρονική κατανομή των ιστορικών και ενόργανων ισχυρών σεισμών για την περίοδο 1600-2000. Υπολογίζονται οι παράμετροι της σχέσης Gutenberg-Richter και στη συνέχεια υπολογίζονται η μέση περίοδος επανάληψης, το πιθανότερο μέγιστο ετήσιο μέγεθος στη περιοχή, καθώς και το μέγιστο μέγεθος σεισμού που μπορεί να δώσει κάθε ρήγμα της περιοχής, υπολογισμένο βάσει του μήκους του.

This thesis is an attempt to gather information on the most important faults in Northern Greece, as well as to study the seismicity of the region. At the same time, there is a review of historical earthquakes that occurred in the study area and their impact on the natural and human environment. The completeness of the earthquake catalogs used in the study is investigated using the Goodness-of-Fit Test (GFT) for two different periods, from 2008-2019 and from 1911-2014, while the temporal distribution of historical and instrumental strong earthquakes is studied for the period from 1600-2000. The parameters of the Gutenberg-Richter relationship are calculated, and subsequently the mean recurrence period, the most likely maximum annual size in the area, as well as the maximum earthquake size that each fault in the area can produce, based on its length, are calculated.
