Περίληψη

Στην εργασία αυτή μοντελοποιήθηκε το τοπικό πολύπλοκο σύστημα ρηγμάτων που συνδέεται με του τρεις ισχυρούς σεισμούς (Mw6.1, Mw5.3 και Mw6.0) της σεισμικής ακολουθίας του Ιανουαρίου-Φεβρουαρίου, 2014, στη Κεφαλονιά και του κύριου σεισμού (Mw6.4) της 17ης Νοεμβρίου 2015 στη Λευκάδα ώστε να διερευνηθούν α) η αλληλεπίδραση των ρηγμάτων κατά την ακολουθία της Κεφαλονιάς το 2014, β) η επίδραση των τριών ισχυρότερων σεισμών της Κεφαλονιάς (2014) στο ρήγμα που προκάλεσε τον σεισμό του 2015 στη Λευκάδα, και γ) η επίδραση όλων των προηγούμενων σεισμών σε γειτονικά ρήγματα της περιοχής, υπολογίζοντας τις στατικές μεταβολές των τάσεων. Τα αποτελέσματα δείχνουν μια σύνθετη κατανομή της μεταβολής των τάσεων στις περισσότερες των περιπτώσεων, με εξαίρεση το ρήγμα F4 (σεισμός Λευκάδας), το οποίο φαίνεται να φορτίζεται ελάχιστα από τάσεις μετά τους σεισμούς της Κεφαλονιάς, και το ρήγμα «Άσσου-Σκάλας», το οποίο φαίνεται να αποφορτίζεται μετά από την αθροιστική επίδραση των ρηγμάτων της Κεφαλονιάς και της Λευκάδας.
