The world was introduced to the world after the devastating impact of the 2004 tsunami that killed hundreds of thousands of people in the 2011 off the Pacific coast of Tohoku Earthquake and the Sumatra Island Earthquake in Indonesia.
The tsunami appears to be more effective in open oceans such as the sea, but the sudden rise in water experienced on the coast after the earthquake off Izmir Seferihisar last year is somewhat dangerous in Turkey as well. Showed that there is a possibility.
Karafat, Director of the Bogaziçi University Regional Earthquake and Tsunami Monitoring and Evaluation Center, assessed the center’s activities and tsunami risk in Turkey within the “Earthquake Week from March 1st to 7th”.
“Some infrastructure work is done.”
Karafat explained that he has begun efforts to establish a research center after the tsunami disaster that occurred after the 2004 Sumatra earthquake in Indonesia, and to become the tsunami warning center of the United Nations Maritime Commission in 2017. He said he had completed some infrastructure work. The certification has been completed.
Karafat said it continues to function primarily as a tsunami observation and warning center in the eastern Mediterranean, with the most important feature of the center being the presence of water level and seismic stations.
“Wait 2 meters in the Sea of Marmara”
Karafat describes Turkey’s tsunami-risk area, which is surrounded by the sea on three sides:
“Mainly the Aegean Sea and the Mediterranean are more dangerous to us. Tsunamis of more than 3 meters can occur on the southwest coast around Crete, Mugla, Gokoba, Fethiye and Antalya. The Mediterranean is actually the African plate. Below the Aegean-Anatolian plate, it is the plate boundary where it sinks. Large earthquakes also occur at the plate boundary. Historical records show that there were significant tsunamis around Crete and the 12 islands. For example, the expected tsunami in Muğla can occur after a major earthquake of magnitude 7. Even if the water level rises by 2 meters, problems and damage can occur in certain areas.
Emphasizing that tsunami-related studies should be carried out in areas near the coast, especially in the Mediterranean region, Karafat has three deep holes in the Sea of Marmara, over 1000 meters, thick walls and young alluvium. Said to be surrounded. Sediment.
Karafat said the possible tsunami was due to the movement of the affected sedimentary layers after the great earthquake, and emphasized that the expected tsunami in the Sea of Marmara would be caused by landslides.
“Important to prevent end-of-earthquake danger”
Dr. Doğan Kalafat of the Association stated that it has the ability to warn early about tsunamis even in the absence of an earthquake, and that this is important to eliminate the second danger after the earthquake.
“We can warn you early about a tsunami in about 4-7 minutes. This time is also important. After receiving this information, the community will reach a safe place from the tsunami shelter. By placing water level stations throughout Turkey, more often, both earthquakes and water levels will come from here. With knowledge of tsunami magnitude and development, we have the ability to provide early warning. I have. “I used the phrase.
Karafat said tsunamis that can occur as a result of earthquakes that can occur especially in the Aegean Sea and the Mediterranean Sea need to be watched, and the tsunami in Turkey does not cause as great a disaster as the open ocean. I explained.
“Earthquakes over 6 years are at risk of tsunami.”
Karafat continued, saying that structures in the coastal area could be damaged.
“Society should be aware that after an earthquake that occurs on the seabed, for example, if the magnitude of the earthquake exceeds 6, a tsunami can occur. Be careful of warnings and evacuate away from the coast. Society should see this as a reflection. Signs of a tsunami should also raise awareness. It is also important. “
Recalling that in the past, after more than six earthquakes off the coast of Fethiye, people panicked for days for fear of a tsunami, Karafat could have a tsunami 20-30 minutes after the quake. I said there is. It won’t come in a few days.
Providing information about the Turkish Tsunami Observatory, Karafat stated that their institute is the only service provider to send mapped messages.
Turkey said there were 25 water level stations, and Kalafat said the stations were mainly located in the Sea of Marmara and across the Turkish coast.
Karafat explained that it is important to increase the number of these stations: “Our country is in a dangerous area of natural disasters. Therefore, our society is aware of the subsequent earthquakes and tsunamis. At the same time, in addition to living in earthquake-resistant buildings, you should not build houses on the coast or riverbed. These places will be damaged by earthquakes and tsunamis that can occur after an earthquake. Let’s do it. “
