- Аннотация: This study is an attempt to determine potential tsunamigenic morphostructural nodes inGreece using pattern recognition algorithms. The earthquakes that have produced local tsunamisin the region were confined to morphostructural nodes whose locations were foundby morphostructural zoning. The recognition problem consisted in separating all nodes inthe region into the tsunamigenic class and the non-tsunamigenic class based mainly on thegeomorphologic parameters of the nodes. The data on tsunamigenic earthquakes in Greecefor training the Cora-3 algorithm were taken from the GHTD global historical catalog oftsunamigenic events (http:// www. ngdc. noaa. gov/ hazard/ tsu_ db. shtml). The recognitionprocedure resulted in determining 27 tsunamigenic nodes, with most of these being situatedin the southern tip of the Peloponnese Peninsula, as well as in the gulfs of Corinthand Patras. Three tsunamigenic nodes were identified in the area of the Malian Gulf on theAegean coast of Greece. According to the relevant literature, most local tsunamis in Greecewere initiated by submarine slides and slumps due to earthquakes. According to the characteristicgeomorphologic features derived in this study, the tsunamigenic nodes are situatedin settings of contrasting relief characterized by steep slopes. This favors submarinelandslides when subjected to earthquake excitation. The results reported in this paper forma basis for developing a methodology to be used in long-term tsunami hazard assessment,supplying information on local potential tsunamigenic sources required for tsunami regionalizationof coastal areas in Greece.
