TÜBİTAK Marmara Research Ship returned to İzmir

Within the framework of the “Determination of Seismicity and Active Tectonic Characteristics of Faults in Kuşadası Bay with High Resolution Seabed Measurements”, which is the first marine research project carried out in the earthquake area with national resources, the ship sailed on May 31 and returned to İzmir Port.

Attending the welcoming ceremony, TÜBİTAK President Prof. Dr. Hasan Mandal, in his statement, said that the ship carried out intensive research for the seismicity and active tectonic features of the faults in the region for about 2 weeks, and bathymetric analyzes and acoustic measurements were made within the scope of the study.

“All of the preliminary information necessary to map this region has been obtained.” Mandal said, noting that valuable information was obtained in the first time of the project.

Mandal gave the following information:

“There is information obtained for the first time. It was the first study carried out in international waters. With the information obtained, we now know this region much more closely. A quick study will be carried out in 2-3 months. After the mapping studies, a second expedition will be launched. “Samples will be taken. With the aging method, we will see which earthquake intervals have occurred in the past in this region and how it will map us to the future. All of these will be shared with the public.”

– “We provided 1300 kilometers of acoustic data”

Istanbul Technical University (ITU) Geological Engineering Department Doctor Lecturer Gülsen Uçarkuş, who is part of the team, said that earthquake research at sea is more laborious and requires high technology.

Noting that they wanted to be able to reveal a map of the sea floor, especially in their studies on the sea part of the active fault systems in the region, Uçarkuş said that they used a system to analyze the faults that cut the layers in the sea. Uçarkuş stated that the team worked intensively and devotedly, “We collected 1300 kilometers of acoustic data.” said.

Noting that they were able to observe how faults with vertical components cut the layers with acoustic data, Uçarkuş said:

“This will enable us to make a successful map here. Our ultimate goal is to determine the deformations of the layers of the earthquakes that occurred in the past by conducting geological sampling around the active faults we detected in the second leg. We will find the deformations of the earthquakes that have occurred in the past. We aim to obtain important scientific findings about the seismicity of the faults.”

Dokuz Eylul University (DEU) Marine Sciences and Technology Institute Faculty Member Prof. Dr. Derman Dondurur, on the other hand, stated that the researches continue day and night, and that the scientific results obtained are very valuable.

Stating that they observed that the activity of the Tuzla Fault on the sea floor is much more intense in the studies, Dondurur said that this shows that the fault is longer than expected.

Dondurur noted that there is a basin especially in the southwestern part of the study area, and that they obtained data that would enable them to make inferences about how this structure, which extends to a depth of 1200 meters, was formed.

Noting that there is no clear date yet for the second research expedition, Dondurur added that plans are being made for the autumn months.
