Faculty members from Istanbul Technical University, Yıldız Technical University and Boğaziçi University came to the region on Friday after the earthquake with a 6.8 magnitude earthquake in Elazig. Scientists measuring the fault line that passes through the Eastern Anatolia Region and stretches from Hatay to Bingöl’s Karlıova district, to collect data that includes aftershocks.
6 seismographers, established since 2015, between Sivrice and Palu, consisted of 2 constantly working GPS stations, 25 GPS measuring points and 2 creepmeters, and scientists made measurements and observations. Scientists collected the data to record the aftershocks that occurred after the 6.8 magnitude earthquake in Sivrice.
SURFACE DEFORMATIONS OF 6.8 EARTHQUAKE DETERMINED
Boğaziçi University Kandilli Observatory Head of Geodesy Department Professor. Dr. Hayrullah Karabulut, Yıldız Technical University, Department of Geomatics Engineering Professor. Dr. Prof. Dr. Uğur Doğan and Boğaziçi University Kandilli Observatory Geodesy Faculty Member. Dr. Semih Ergintav recorded the data in the seismograph in the district of Palu on the banks of the Murat River.
Scientists also identified the surface deformations of the earthquake of 6.8 magnitude with the data and examinations obtained. Scientists found that with the earthquake, there were no breaks and deformations on the surface of the earth, only landslides and crevices occurred in the second impact position. Scientists who will process the collected data will contribute to studies related to earthquakes with the findings.
“WE ARE WORKING TO MODEL THE FAULT MOVEMENT”
Yıldız Technical University, Department of Geomatics Engineering Professor. Dr. Uğur Doğan said that they tried to solve the mechanism on the fault line passing through the Eastern Anatolia Region with 3 different earth science. Professor Dr. Doğan added that they would model the movement on the fault by gathering all the information and said:
* We use 3 different geoscience techniques together with the groups in geodesy, geophysics and geology departments. As geodesy we have placed GPS points here. We have now installed 2 fixed and continuously operating GPS stations in the south and north of the fault. It has been working since October.
* These are the stations where we can see the effect of this earthquake directly in case of an earthquake here. In addition, we have established 2 geodetic stations and 2 fixed stations in this region. We periodically determine position changes. We placed earthquake devices as geophysical studies.
* We have now placed 1 in Palu, 3 in Sivrice and 1 in Pütürge. We have 6 earthquake devices in the region. In addition, geologically, our friends at Istanbul Technical University conducted some geological surveys in the region through field studies.
* They took soil samples, and we are trying to solve the mechanism on the fault by evaluating them in geochemical laboratories. We try to model the fault movement by bringing all the information together.
“WE HAVE SEEN WITHOUT SURFACE FRACTURE”
Professor of Geodesy, Boğaziçi University Kandilli Observatory. Dr. Semih Ergintav stated that there was no deformation on the surface of the earthquake of 6.8 magnitude in the epicenter of Sivrice. Professor Dr. Ergintav said that they found that landslides and crevices on the roads, which were only the second effect with the earthquake, formed:
* Our way of working after the earthquake is to quickly go to the region and understand why the earthquake occurred about the region. We install devices with friends from various universities, make observations. As far as we can see as a result of the earthquake, we can see from the observations of the different devices we have obtained that the incident that started deeply did not reach the surface and its energy was not enough.
* Therefore, we have seen that it does not create a surface fracture on the surface as in a very clear 99 earthquake. Of course, there are cracks and slips on the surface. All of them are actually secondary events. Basically, there is no deformation on a main surface caused by such an earthquake. There are more widespread deformations that are spreading at his rather than.
* You see their effects very easily from cracks, fractures and explosions on the roads. Perhaps the fact that the damage is low and the loss of life is low is such an advantage.
* Of course, it depends on the characteristics of this fault. Now, with the data we have collected, we will understand the characteristics of this fault and try to model why it is not enough to breathe. (DHA)
