Tarsus was formed from the geological time formations shown below.
a) Quaternary - These occurrences from the limestone tuffs of the fourth time (Travertine) were formed in a diagenetic way by the sedimentation of the underground waters containing cola carbonate to the surface. The said formation starts from the virtuous town of the province of Icel, it extends in the form of a strip until the Kurttepe site to the north of the province of Adana. This acknowledgment is often called stay. These limestone tuffs (travertine), which are yellowish, gray and white in color, are robust and most suitable for structure based flooring.
b) The fields that come out of the alluvium are usually the ones that leave Berdan Stream. These formations consist of a mixture of clay, sand and gravel, and the thickness of the alluvium increases as they turn towards the ovary. Alluviums with a moderate structure are suitable for building-based floors.
c) The old debris on alluvium consists of alluvials from the field, and there is an old rubble fill on these fields. Because of Tarsus is an old town, it is to find ruins and monuments belonging to the nations that have settled here before. These areas are suitable for structure-based flooring. In addition, when there is a rubble fill on the area, it is necessary to place the building bases on a solid ground.
The survey area is taken to third degree in terms of seismicity. Because it lies in the area of influence of the active fault line extending in the north-south direction passing through Kadirli Misis to the east of Adana. The buildings to be built in Tarsus must be observed according to the principles of earthquake regulations.
