20 July, 2017 Bodrum-Kos earthquake occurred in Gokova Bay caused a tsunami and majority of the marine vessels have significantly been dragged by the tsunami. There were minor, moderate and major damages on the marine vessels in Gumbet Bay. The current velocities and water elevation changes caused by tsunami are computed from the mathematical model NAMI DANCE by applying the three different tsunami source models and the source which results in the most compatible results with the field survey observations is selected. Then, the damage on the boats are extracted from the field survey findings. A complete analysis of the damage distribution of the vessels is performed. The computed current velocities and water elevations as well as damage findings and vessel properties are used in developing tsunami fragility curves. The resulted fragility functions for the boat damage in Gumbet Bay are presented and discussed.

Investigation of Hydrodynamic Parameters and the Effects of Breakwaters During the 2011 Great East Japan Tsunami in Kamaishi Bay Sozdinler, Ceren Ozer; Yalçıner, Ahmet Cevdet; Zaytsev, Andrey; Suppasri, Anawat; Imamura, Fumihiko (2015-12-01) The March 2011 Great East Japan Tsunami was one of the most disastrous tsunami events on record, affecting the east coast of Japan to an extreme degree. Extensive currents combined with flow depths in inundation zones account for this devastating impact. Video footage taken by the eyewitnesses reveals the destructive effect and dragging capability of strong tsunami currents along the coast. This study provides a numerical modeling study in Kamaishi Bay, calculating the damage inflicted by tsunami waves on s...
The possibility of tsunami in the Sea of Okhotsk caused by deep-focus earthquakes Zaytsev, A. I.; Pelinovsky, E. N.; Kurkin, A. A.; Kostenko, I. S.; Yalçıner, Ahmet Cevdet (2016-03-01) The earthquake that occurred on May 24, 2013, in the basin of the Sea of Okhotsk with a magnitude of 8.3 was the strongest in this region. We have modeled a possible tsunami caused by such an earthquake. The simulations confirm that the wave heights were sufficiently small because the earthquake epicenter depth was 640 km. We analyze the oscillations of the DART buoys in the vicinity of the earthquake source and show that they were not associated with the tsunami waves. Analysis of the available pressure ga...
Reconnaissance of 2020 M 7.0 Samos Island (Aegean Sea) earthquake Çetin, Kemal Önder; Sextos, Anastasios; Stewart, Jonathan P. (2021-08-01) The Samos Island (Aegean Sea) Earthquake occurred on 30 October 2020. It produced a tsunami that impacted coastal communities, ground shaking that was locally amplified in some areas and that led to collapse of structures with 118 fatalities in both Greece and Turkey, and wide-ranging geotechnical effects including rockfalls, landsliding, and liquefaction. As a result of the global COVID-19 pandemic, the reconnaissance of this event did not involve the deployment of international teams, as would be typical ...
Simulation of seismic triggering and failure time perturbations associated with the 30 October 2020 Samos earthquake (Mw 7.0) Sopaci, Eyup; Özacar, Atilla Arda (2021-01-01) The 30 October 2020 Samos earthquake (Mw = 7.0) ruptured a north-dipping offshore normal fault north of the Samos Island with an extensional mechanism. Aftershocks mainly occurred at the western and eastern ends of the rupture plane in agreement with the Coulomb static stress changes. Mechanism of aftershocks located west of the rupture supported activation of the neighboring strike-slip fault almost instantly. In addition, a seismic cluster including events with Mw similar to 4 has emerged two days later a...

Immediately after the earthquake, we conducted several post-tsunami field surveys including interviews in coastal zones impacted by the tsunami, i.e., the coastlines of Bodrum Peninsula, Karaada Islet and Akyaka Town in Gokova Bay, Turkey, and eastern Kos Island, Greece. We present observations and measurements to document the variation of the tsunami effects al...
