The evacuation response against the earthquake and tsunamis is very important for the reduction of human damages against tsunami. But it is very difficult to predict the human behavior after shaking of the earthquake. The purpose of this research is to clarify the difference of the human response after the earthquake shock in the difference countries and to consider the relation between the response and the safety feeling, knowledge and education. For the objective of this paper, the questionnaire survey was conducted after the 21st July 2017 Gokova earthquake and tsunami. Then, consider the difference of the human behavior by comparison of that in 2015 Chilean earthquake and tsunami and 2011 Japan earthquake and tsunami. The seismic intensity of the survey points was almost 6 to 7. The contents of the questions include the feeling of shaking, recalling of the tsunami, the behavior after shock and so on. The questionnaire was conducted for more than 20 20 people in 10 areas. The results are the following; 1) Most people felt that it was a strong shake not to stand, 2) All of the questionnaires did not recall the tsunami, 3) Depending on the area, they felt that after the earthquake the beach was safer than being at home. 4) After they saw the sea drawing, they thought that a tsunami would come and ran away. Fig. 1 shows the comparison of the evacuation rate within 10 minutes in 2011 Japan, 2015 Chile and 2017 Turkey.. From the education point of view, education for tsunami is not done much in Turkey. From the protection facilities point of view, the high sea walls are constructed only in Japan. From the warning alert point of view, there is no warning system against tsunamis in the Mediterranean Sea. As a result of this survey, the importance of tsunami education is shown, and evacuation tends to be delayed if dependency on facilities and alarms is too high.

Possible worst-case tsunami scenarios around the Marmara Sea from combined earthquake and landslide sources Latcharote, Panon; Suppasri, Anawat; Imamura, Fumihiko; Aytore, Betul; Yalçıner, Ahmet Cevdet (2016-12-01) This study evaluates tsunami hazards in the Marmara Sea from possible worst-case tsunami scenarios that are from submarine earthquakes and landslides. In terms of fault-generated tsunamis, seismic ruptures can propagate along the North Anatolian Fault (NAF), which has produced historical tsunamis in the Marmara Sea. Based on the past studies, which consider fault-generated tsunamis and landslide-generated tsunamis individually, future scenarios are expected to generate tsunamis, and submarine landslides cou...
Broadband ground motion simulation within Duzce city (Turkey) Özmen, Ekin; Askan Gündoğan, Ayşegül; Kestel, Sevtap Ayşe; Department of Earthquake Studies (2019) Earthquakes have more hazardous and devastating effects in populated areas. To prevent damage and reduce the risks, broadband records are collected to use in the seismic hazard assessment and engineering seismology. In areas with significant seismic activity and insufficient seismic networks, the simulated ground motions become more important. Broadband ground motion simulations are performed for 12 November 1999 Duzce earthquake. Deterministic simulations are performed for low frequency part and stochastic...
Numerical Modeling of Long Waves from Atypical Sources: Atmospheric Disturbances and Volcanic Origin Doğan Bingöl, Gözde Güney; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2022-6-30) Earthquakes are the main cause mechanisms of tsunamis and large tsunamigenic earthquakes, especially in the subduction zones, occur on relatively much shorter timescales, but destructive tsunamis are also produced by volcanic eruptions, which have been threatening the coastal communities throughout history. Furthermore, while earthquake-generated tsunamis have been studied immensely, there is less focus on research related to tsunamis induced by atmospheric disturbances (meteotsunamis). Consequently, this s...
Tsunami human vulnerability assessment of silivri district, Istanbul Tüfekçi Enginar, Duygu; Süzen, Mehmet Lütfi; Yalçıner, Ahmet Cevdet; Zaytsev, Andrey (null; 2018-04-08) Assessment of tsunami human vulnerability is essential for development of tsunami hazard mitigation strategies especially when the possible affected areas are within a metropolis. The Sea of Marmara has faced tsunami events that are both generated by earthquakes or landslides. Therefore, all the coastal districts of the megacity Istanbul are prone to suffer from tsunami events. Some of the coastal districts of Istanbul have been studied in detailed within the concept of tsunami human vulnerability assessmen...
Numerical modelling of the 1766 (May) earthquake tsunami scenario along the northern coasts of Marmara Sea, Turkey Vardar, Hande; Alpar, Şaban Bedri; Yalçıner, Ahmet Cevdet (null; 2018-04-09) Following the recent 1999-earthquake disaster and its associated tsunami that occurred in the Izmit Gulf, eastern part of the Marmara Sea; much research has been carried out to determine the tsunami potential, as well as their possible effects along the adjacent coast. Based on the available archival data, many tsunamis (e.g. 989, 1343, 1509, 1766, 1894 and 1912) have affected the low-lying coasts, bays, estuaries, straits and possibly coastal lagoons along the northern coast of the Marmara Sea. In the pres...
