Comparison of Human Response against Earthquake and Tsunami

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.
