Abstract: Historical records reveal that Turkey coasts faced with a considerable number of tsunamis in its past. Although the tsunamis in the seas surrounding Turkey are not as catastrophic as the ones in Pacific Ocean, still they may cause substantial damage to the highly populated touristic coastal places. Eastern Mediterranean Sea and Aegean Sea are in the seismically active region of Turkey. Therefore, numerous earthquakes and associated tsunamis are threatening the western coasts of Turkey. Recently, two important tsunami events recorded and damaged the coastal areas of Turkey, which are Bodrum-Kos tsunami on 21 July 2017 and Izmir-Samos tsunami on 30 October 2020. These events reminded that the Turkey coasts should be prepared for a tsunami threat. Numerical simulations based on critical worst-case tsunami scenarios are performed with NAMI DANCE numerical model. According to the simulation results, 1956-Amorgos seismic scenario and Gökova seismic and Gökova-North-Datça landslide scenario are selected as critical worst-case scenarios. In this study, evacuation walk time maps are prepared for the highly populated settlements of Bodrum Peninsula by using Pedestrian Evacuation Analyst Tool (PEAT) based on the selected critical scenarios mentioned above. PEAT is a least-cost distance (LCD) evacuation model that estimates evacuation times throughout hazard zone based on elevation, land cover, walking speed and direction of movement. The resultant pedestrian evacuation maps revealed that the evacuation time needed for pedestrian is 8, 6, 5, 4, 3 minutes located in Central Bodrum, Yahşi, Akyarlar-Karaincir-Aspat Bays, Bitez, and Gümbet bays, respectively. The resultant evacuation times are tested and validated by on-site measurements.
