The wind from Turkey from the beginning of the areas exposed to erosion and about 50 thousand with a population of the Konya Karapinar district, withdraws groundwater, sinkholes are caused by the collapse of the land, the region continues to constitute a threat to the public. AFAD Konya Provincial Directorate, Konya Plain Project Regional Development Administration (KOP) and Konya Technical University (KTÜN) Members of the geological engineering faculty initiated a study on sinkholes in the region. As a result of the studies that lasted 5 months, it was determined that there were 505 potholes of various sizes that could be detected in the region.
DETECTED BY SATELLITE
Research team leader, Prof. Dr. Yaşar Eren, Dr. When faculty member Şeyda Parlar and research assistant Berkant Coşkuner examined satellite images, they detected cracks in the surface between the Büyük Çıralı plateau and Acıkuyu, 26 kilometers northwest of the center of Karapınar district. In field investigations, cracks between 10 meters wide and 8-10 meters deep were examined. As a result of the examinations, it was determined that the circular slits belonged to the sump with a diameter of 630 meters.
The road connecting Karpanar with the Eskil district of Aksaray passes over the giant pothole. The road is used by those who live on the plateaus of that region and those who come to visit the potholes of tourist importance.

GIANT BLADE 630 METERS IN DIAMETER
Prof. Dr. Yaşar Eren said the following:
“When we examined satellite images during our work in the region, we found a formation. When we checked, we determined at least 3 circular slits that we could detect. As a result of our studies, we found a sink with a diameter of 630 meters from the cracks on the surface. Pothole cracks can reach 10 meters in places. There is a depth of 8-10 meters along the slits. Of course, when we examine the area of the pothole, there are general landslides around 4-5 meters. Again, within these circular cracks, we observe pothole formations up to 10 meters in diameter and 8 meters deep. This sump is not a new formation. It started to form in the past and its formation has not ended due to some obstacle under the ground, it has not fully developed. “
THE GIANT OBRUK CONTINUES FORMING

Noting that the pothole continues to form and its depth can be determined by detailed examinations, Prof. Dr. Eren said: “When we look at the linear structures in the region, it is a sinkhole that we observe that, especially on the road, the sinkhole is It has deformed, so it continues to form even a little. When we look at the structures in the region, we see that the cracks have warped the road. The pothole continues to form, but the depth below it will be determined by detailed studies in the region. In the region, visualizations and mapping are done in cooperation with AFAD and KOP. Along with geophysical studies, the underground properties of the sump are also determined here. We see that the road that goes through the middle of this pothole is often deformed. “This pothole is a huge sinkhole that formed in the past and continues to form.”
‘OBRUK IS STUCK DUE TO A CERTAIN OBSTACLE’

Research assistant Berkant Coşkuner, who said the pothole could not be formed by an obstacle during its formation, said: “The area we are investigating contains 180 sinkholes along a fracture line. Some of these sinkholes were formed thousands of years ago, and the number of our sinkhole groups, some of which have recently formed or are even continuing to form, is quite high. This sinkhole is still forming and warping the road. This sinkhole endangers the road or the surrounding plateaus. This pothole was blocked due to a certain obstacle and did not completely collapse. “Determining this, how long the depth continues, whether the pothole will continue to move will be revealed as a result of future geophysical studies.”
