Two earthquakes of magnitude 4.9 and 5.2 occurred yesterday in Adana's Saimbeyli and Osmaniye's Sumbas districts. There was no negative situation after the earthquake.
According to the information on the website of the Disaster and Emergency Management Presidency (AFAD), after the 4.8 magnitude earthquake that occurred in Adana at 14.19 yesterday, a second earthquake of 4.9 magnitude occurred at 14.36, with the epicenter in Saimbeyli district.
According to AFAD data, a 5.2 magnitude earthquake was recorded in Osmaniye's Sumbas district at 14.43. It was reported that the consecutive earthquakes occurred at a depth of 8.67 and 7 kilometers, respectively.
It has been noted that no negative situation has been reported so far due to the three earthquakes that occurred within 24 minutes in Adana and Osmaniye.
EARTHQUAKE REPORT FROM AFAD
In the preliminary report prepared by the Disaster and Emergency Management Presidency (AFAD) regarding the 5.2 magnitude earthquake that occurred in Adana's Saimbeyli district, it was stated that 16 aftershocks with magnitudes ranging from 1 to 2.4 were recorded before the earthquake that occurred 7 kilometers deep.
AFAD published a preliminary assessment report regarding the 5.2 magnitude earthquake, whose epicenter was in Adana's Saimbeyli district, at 14.43 today. According to the report, the earthquake occurred at a depth of 7 kilometers underground. The closest settlement to the epicenter of the earthquake; It became Akoluk village in Feke district, 7,114 kilometers away. The report stated that 16 aftershocks with magnitudes ranging from 1.0 to 2.4 were recorded between the main shock and 12:58. It was stated that the fault that caused the earthquake will be determined as a result of detailed seismological and field studies.
The report stated that 32 earthquakes of magnitude 4 or higher have occurred in the region since 1900, the largest being 5.7. It was also noted that there were 3 historical earthquake records in the region dating back to before 1900. AFAD stated that the information in the report was compiled with the data produced within the first hour following the earthquake and warned that if there are damaged structures in the region, these structures should not be used.
PROF. SÖZBİLİ: IT MAY CONTINUE AS AN EARTHQUAKE STORM
Dokuz Eylül University Earthquake Research and Application Center Director Prof. Dr. Regarding the earthquakes in Adana and Osmaniye, Hasan Sözbilir said, "Both the Saimbeyli Fault and the Savrun Fault are considered faults where energy accumulation occurred after the February 6 earthquakes. At this stage, earthquakes of similar magnitude may continue their activity in the form of earthquake storms." he said.
Sözbilir, who is also a member of the Earthquake Science Board of the Disaster and Emergency Management Presidency, stated in his written statement that 3 medium-sized earthquakes occurred in 24 minutes.
Noting that these earthquakes were between the Savrun and Saimbeyli faults, Sözbilir said:
"After the Ekinözü earthquake of February 6, 2023, there were hundreds of earthquakes with a magnitude of up to 5 from the south of Göksun to Kozan-Kadirli. Both the Saimbeyli Fault and the Savrun Fault are considered faults with energy accumulation after the February 6 earthquakes. At this stage, earthquakes of similar magnitude may continue their activity in the form of earthquake storms. It is very important for the public not to panic and to act in line with the directives of the competent authorities."
PROF. GÜNEYLI: THE ACCUMULATED ENERGY OF THE FEBRUARY 6 EARTHQUAKES
Çukurova University Faculty of Engineering Department of Geological Engineering Lecturer Prof. Dr. Regarding the earthquakes in Adana and Osmaniye, Hakan Güneyli said, "When we evaluate the data so far, we can say that these earthquakes will become smaller and their occurrence intervals will be extended." he said.
Reminding that the region was affected by the February 6, 2023 earthquakes centered in Kahramanmaraş, Güneyli said, "We can express these earthquakes as earthquakes that occur as a result of the transfer of the elastic deformation energy that occurred in the February 6 earthquakes towards the west and southwest, and the energy accumulated there is somehow released." he said.
Speaking to Anadolu Agency, Güneyli stated that according to current data, earthquake activity continues in the form of tremors that decrease over time and said:
"When we examine the earthquakes that have occurred so far, we see that before the largest earthquake of 5.2, there were 5 smaller earthquakes, and after 5.2, there were 22-25 more earthquakes, and that these earthquakes continue to decrease in the form of a series of earthquakes smaller than 5.2. When we evaluate the data so far, we can say that these earthquakes will become smaller and fade away by extending their intervals of occurrence. Aftershocks may continue, like the aftershocks of the previous magnitude, but with longer intervals." "Aftershocks may occur."
"I THINK THE KARATAŞ-YUMURTALIK Fault HAS THE POTENTIAL TO CAUSE EARTHQUAKES"
Prof. Dr. Hakan Güneyli stated that energy transfer could continue for years after the February 6 earthquakes.
Evaluating the faults in the region, Güneyli said, "I think that the Karataş-Yumurtalık fault has the potential to cause an earthquake in the coming period." shared his opinion.
Güneyli pointed out that risks such as landslides and rockfalls increase after earthquakes and said:
"We are currently going through a very rainy period. In this context, when we associate the high slope, geological conditions, ground conditions and rainfall with the earthquake, the combination of many factors may reveal the risk of serious mass movements in that region. In this sense, it is especially beneficial for our people living in the region to live by paying attention to mass movements."
