GOGOU, M., ANDREADAKIS, E., NOMIKOU, P., LEKKAS, E. (2018). – Previewing tsunami risk in coastal zone of southern Aegean Sea. Proceedings 9th International INQUA Workshop on Paleoseismology, Active Tectonics and Archeoseismology (PATA Days 2018), pp. 75-78, 25-27 June 2018, Possidi, Greece.
This paper attempts to assess the tsunami risk in the area of the southern Aegean Sea as well as to preview this hazard in the present coastal areas of Folegandros, Sikinos, Irakleia, Schinoussa, Koufonisia, Keros, Amorgos, Astypalea, Anafi and Santorini. The risk zonation of these coastal zonesis based on measured run up values recorded in the last historical tsunami, after the Amorgos earthquake in 1956. The risk zones are overlain in current land uses of the islands and satellite imagery, highlighting the impacts of a potential tsunami in southern Aegean Sea in residential, tourist, industrial and agricultural areas. According to the risk assessment Matrix (using probability, frequency and intensity of tsunami) ,the study area requires organizational measures on the allocation of responsibilities and response, whereas, Santorini, Amorgos, Folegandros, quire immediate action, detailed planning and distribution of responsibilities at local and national level, as well as monitoring of tsunami.
