While the consecutive earthquakes that occurred off the coast of Yalova in the Marmara Sea were felt in Istanbul and surrounding provinces, Geology Specialist Prof. Dr. Osman Bektaş evaluated seismic activity.
AI-generated summary
Earthquakes of magnitude 3.5 and 3 occurred off the coast of Yalova in the Sea of Marmara.
Earthquakes occur one after the other off the coast of Yalova in the Sea of Marmara.
Citizens became uneasy due to the tremors felt in Istanbul and surrounding provinces.
While the fear of a "big earthquake" that has been expected for years, especially for Istanbul, is still fresh; It was wondered what the earthquakes of magnitude 3.5 and 3 meant.
PROF. DR. BEKTAŞ DRAW ATTENTION TO THE EARTHQUAKE 10 YEARS AGO
Sharing his assessment on the subject, Geology Specialist Prof. Dr. Osman Bektaş pointed out that the seismic activity in the region should be examined in terms of the possibility of slow slip on the faults.
Bektaş gave information about the study published by a German research team in 2019 and stated that the microearthquake movement observed before and after the 4.4 magnitude Yalova earthquake in 2016 was associated with the slow slip in the Çınarcık fault.
Pointing out that there was a deformation signal lasting approximately 50 days around the earthquake recorded in 2016, Bektaş stated that the earthquake that occurred in 2026 should also be evaluated in terms of the creep behavior of the faults in the Marmara.
Bektaş emphasized that the two earthquakes that occurred a day apart off the coast of Yalova may indicate the slow sliding behavior of the faults.
"BENEFIT STRENGTHENES THE POSSIBILITY OF SLOW SLIPPING"
Bektaş's statement included the following statements:
"In the 2019 study of the German team, the microearthquake activity before and after the Yalova 4.4 earthquake in 2016 was interpreted as the slow sliding of the Çınarcık fault.
Today's Yalova 3.5-2.9 earthquakes also support the creep behavior of the faults in the Marmara.
This deformation signal, which lasted approximately 50 days around the 2016 Yalova earthquake and the 2026 microearthquake event, strengthens the possibility of fault creep. For this reason, seismic activity in Yalova should be monitored with scientific data, not with fear."
Within the scope of Ufuk Europe BiodivERsA+, the 2026 "BiodivFuture" call is open for applications. TÜBİTAK announced the application conditions and dates for researchers in Türkiye.

Scientists at METU Marine Sciences Institute conducted a 1-week scientific expedition in the Black Sea and examined the physical, chemical and biological properties of sea water. During the research, nano-sized particle clouds rich in metals such as iron, manganese, copper, zinc, tungsten and molybdenum were detected, where particles coming from the seashore dissolved and accumulated. Institute Deputy Director Prof. Dr. Mustafa Yücel warned that these clouds are an important indicator in understanding the distribution of marine pollution and that extreme weather events related to climate change can carry these metals to the surface and make them toxic. He also stated that these natural formations can be a source of inspiration for nanotechnology, material science and space science research.

A statement was made by AFAD after the 3.5 magnitude earthquake in the Marmara Sea the day before; The earthquake occurred at a depth of 7.9 km and was felt in Istanbul. Geological experts stated that the earthquake was related to the weak crust of Marmara and the creeping fault behavior, and emphasized that there was no risk of a major earthquake. A second earthquake with a magnitude of 2.9 was recorded off the coast of Yalova last night.
The POTASSIAL project, carried out under the coordination of İnönü University, has been completed. With the project, feldspar mining wastes were evaluated with a zero waste approach and strategic raw materials such as alumina, potassium chloride and silicon carbide were obtained.

A 3.5 magnitude earthquake occurred off the coast of Yalova in the Sea of Marmara at 22.08. According to AFAD data, the earthquake, with a depth of 7.96 km, was felt slightly around Kartal and Tuzla in Istanbul. Evaluating the earthquake, Prof. Dr. Şener Üşümezsoy stated that the earthquake did not occur on the main Marmara Fault or Adalar Fault, but instead resulted from a small break in the secondary fault branches, and such faults do not have the potential to produce major earthquakes.

Researchers from Leibniz University and Helmholtz-Zentrum Dresden-Rossendorf have determined that radioactive fuel particles emitted from Chernobyl can remain in the environment for a long time and pose a health risk, preserving their original structure.
