Ordu Giresun Airport Collapses!

Scientists proved that after the Trabzon Stadium, there were also collapses in the filling area where Or-Gi Airport is located. Ordu-Giresun Airport, which was built entirely by filling the sea, was put into service in 2015.

Scientists, who followed the filling area for a year and a half with the European Space Agency's Sentinel-1 satellite, detected a collapse in the north of the area where the airport is located and a rise in the south.

SözcüAccording to the news of Yusuf Demir; Assoc. Dr. Saygin Abdikan and Dr. from Bulent Ecevit University. The article prepared by Çağlar Bayık included the following determinations:

The graph shows the deformation at the airport. Experts note that the subsidence or elevation of the ground, not as a whole, causes a crushing effect on the superstructure.

The color differences in the graphic also show that the filling area where the airport is located does not move as a whole.

Surface Deformation Determined

In this study, the surface deformation of Ordu-Giresun Airport, which was founded in 2011 and became operational in 2015, was determined.

Viewed by Satellite for 19 Months

For this purpose, Sentinel-1A/B satellite images belonging to the European Space Agency and time series were analyzed with PSI technique.

The red areas show the collapse as you go to the dark blue. According to the chart, the sea side tends to subside while the land side is rising.

14 Milimeters Collapses a Year, 9 Millimeters Rise

As a result of the analysis, it was determined that the amount of deformation at Ordu-Giresun Airport between August 2017 and February 2019 was between -14 and +9 mm.

Ground Foundations Moving

The foundations of the land, which was built with filling on the sea where Ordu-Giresun Airport is built, has a settlement-sensitive and geologically active structure.

The Ministry Says It's Solid But

According to the report of the Ministry of Transport (2012), it is stated that the area will show a solid ground feature and there will be no settlement problem depending on time. According to the study, although there is no expectation, movement is observed. While the movement is generally determined as collapses in the northern parts of the airport, it has been determined that the uplift is more dominant in the southern parts, but it occurs in the form of collapses in places.

Vital to Watch

This situation can cause negative effects especially in areas with high population. Ensuring operational safety at airports built on such areas is of vital importance in terms of public safety, and surface deformation should be monitored on a regional scale to ensure this safety. It is very important to monitor and monitor the deformation of this structure.

''After the filling is done, it should be followed for at least one year''

What these data mean, retired geology expert from Karadeniz Technical University, who has been working in the region for 45 years, is a veteran faculty member. prof. Dr. Osman Bektaş explained to SÖZCU: 

• The data of this scientific study published in an international peer-reviewed journal are very clear. Just as Akyazı collapses, Ordu and Giresun Airports collapse in the same way.
• The coastal geology of both areas is the same. Errors are repeated because the filling system is the same. The north of both embankments, that is, the sea side, is collapsing, and the land side is rising.
• It seems that the future of hospitals, stadiums and airports built on those fillings is at risk.
• The fact that the deformations are not immediately noticed, and their emergence over a long period of time causes political abuses. We are trying to cost less in less time.
• As soon as we made the filling in both Akyazı and Ordu-Giresun, we built the superstructure on it. After understanding how these embankments sit for at least a year, after determining the stability of the embankment, static calculations should be made on the superstructure.
• Rize was filled with the same system in the 1960s. That day, they were almost going to erect a statue of the mayor who filled that sea. The same people of Rize are devastated today. Rize is a sinking city today.
• If we continue to make these mistakes, we will leave infill areas and structures whose fate is uncertain for the next generation. This nation's money will be wasted. We need to make filling regulations at the international level.
