A series of earthquakes struck southern Turkey on the afternoon of October 4, 2026, centered on the Saimbeyli district of Adana Province and the Sumbas district of neighboring Osmaniye Province, according to Turkey's Disaster and Emergency Management Authority (AFAD).
The first tremor, with a magnitude of 4.8, was recorded at 14:19 local time in Saimbeyli at a depth of 7.99 kilometers. A second earthquake measuring 4.9 struck the same district just 17 minutes later, at 14:36, at a depth of 8.67 kilometers. A third quake, measuring 5.2, hit Sumbas in Osmaniye at 14:43, at a depth of 7 kilometers, AFAD data cited by Türkiye Today and Hürriyet showed.
What officials said
AFAD issued a statement after the first tremor saying that, as of that moment, "there is no adverse situation," and that field survey teams were continuing their work across the affected districts, according to Türkiye Today.
Interior Minister Mustafa Çiftçi addressed the earthquakes shortly after the third tremor, saying AFAD and other relevant state institutions had immediately begun field surveys in Adana and Osmaniye and that no negative situation had been identified at that point, according to NET HABER, which published his statement at 15:19. Environment, Urbanism and Climate Change Minister Murat Kurum also said no negative situation had been reported, adding that authorities were monitoring the region and evaluating incoming reports, and he extended condolences to residents of both provinces, Milliyet's Uzmanpara section reported.
No casualties or damage reported so far
According to all sources consulted, no deaths, injuries or structural damage had been reported in either province as field teams continued inspections after the three tremors. The earthquakes were felt in surrounding provinces, Türkiye Today reported.
Saimbeyli and Sumbas lie in a seismically active part of southern Turkey that was affected by the devastating earthquakes of February 6, 2023, which struck a different fault system further east, Türkiye Today noted in its coverage of the October 4 tremors.

The Baku-based outlet Report.az, citing AFAD, reported that four earthquakes were recorded across Turkey on October 4, including a separate 4.8-magnitude tremor in Muğla Province, in addition to the two Saimbeyli quakes and the Sumbas earthquake in Osmaniye.
