Expedition of Turkey’s First Earthquake Research in National Waters Completed
First naval expedition of earthquake research in the national waters project carried out under the leadership of İstanbul Technical University (İTÜ) with the support of TÜBİTAK was completed. An 11 member scientific research team including a geophysicist from the Disaster and Emergency Management Authority (AFAD) returned from the two week long expedition. TÜBİTAK Chairman Hasan Mandal, AFAD Earthquake Department Chairman Dr. Murat Nurlu, İstanbul University Rector Prof. Dr. Mahmut Ak and İTÜ Vice Rector Prof. Dr. Bülent İnanç welcomed the TÜBİTAK MAM vessel carrying the research team after it docked at the İzmir Port.
The study which AFAD takes part in is the first earthquake research carried out in waters with national resources. The project aims at drawing a map by defining characteristics of fault lines ranging from land to sea in the aftermath of the İzmir Earthquake. The important phase of the “Project for Defining Active Tectonic Characteristics of Seismicity of Fault Lines by Using High Definition Sea Bottom Measures at the Kuşadası Gulf'' was completed with the conclusion of the first expedition. The research team collected acoustic data from 1,300 kilometer long area during the expedition which started on May 31.
First Study in national Waters
TÜBİTAK Chairman Prof. Dr. Hasan Mandal stated that seismicity of faults and active tectonic characteristics of the region as well as bathymetric analysis and acoustic measures were studied during the 2 week expedition.
"Preliminary information needed for drawing the map of the region was obtained during the research” said Mandal, “first expedition allowed us to gather valuable information. It was the first research carried out in the national waters. After mapping activities which are expected to be completed within 2 to 3 months, the team will begin the second expedition. The second expedition will carry out core sampling. Meanwhile, the aging method will allow us to observe the frequency of past earthquakes and draw a roadmap for the future. We will share this information with the public.”
Earthquake Research at Sea Requires High Technology
Meanwhile, Head of Research Team and İTO Geology Engineering Department academician Dr. Gülsen Uçarkuş stated that earthquake research at sea is harder and requires high technology. Noting that they want to draw the map of the sea bottom before studying the active fault system of the sea in the region, Uçarkuş said that they used a system for analyzing the faults that intersects with layers in the sea.
Uçarkuş stressed that the team had worked hard with sacrifice and collected acoustic data from the 1,300 kilometer long area during the expedition.
Acoustic data will allow scientists to observe how vertical component faults intersect with layers, said Uçankuş and went on to say, “Such information will help to draw a successful map. Our final goal is to take geological core sampling around active faults and deformation in the layers that occur due to past earthquakes. We will detect precipitation and undertake aging. We are aiming at obtaining important scientific data concerning seismicity of faults.”
