Several minor earthquakes were recorded off Turkey's Antalya coast in the Mediterranean on October 21, 2026, according to Turkey's Disaster and Emergency Management Presidency (AFAD). The largest, measured at magnitude 2.8, struck near the Aksu district at 17:32 local time. AFAD said no damage or injuries were reported from any of the day's tremors.
What AFAD recorded near Antalya
The Aksu quake was recorded at a depth of about 7 kilometres, AFAD data cited by Turkish outlets gzt.com and Reflex Haber show. Both outlets reported that initial checks by authorities found no adverse effects following the tremor.
Earlier the same day, AFAD logged a magnitude 2.3 earthquake at 00:13 local time offshore, 97.51 kilometres from the Gazipaşa district of Antalya, at a depth of 16.79 kilometres, according to a list compiled by Habertürk from AFAD data. A separate, much smaller magnitude 1.1 quake was recorded inland in Antalya's Korkuteli district at 00:49, at a depth of 7 kilometres.

Why AFAD and Kandilli figures can differ
Turkey has two main seismic monitoring bodies: AFAD and Boğaziçi University's Kandilli Observatory. For the same 04:21 tremor that AFAD placed in the open Mediterranean at magnitude 2.2 and 5.89 kilometres depth, Kandilli recorded a magnitude 2.4 event near Crete at a depth of 20.1 kilometres, according to the Habertürk compilation of both agencies' data. Differences in seismic station networks and calculation methods routinely produce slightly different magnitude, depth and location estimates for the same event.
The larger, magnitude 3.8 quake two days earlier
Searches linking a magnitude 3.8 earthquake to the Antalya coast largely stem from a separate event on October 19, 2026. AFAD recorded that quake at 17:30 local time in the Mediterranean, 290.53 kilometres from the Datça district of Muğla province — not Antalya — at a depth of 7 kilometres, according to Hürriyet and NTV, both citing AFAD figures. NTV's roundup of AFAD data from that day listed it as the largest of several tremors clustered around Muğla, including smaller quakes near Marmaris, Köyceğiz, Dalaman and Seydikemer.
No damage or injuries were reported from the October 19 quake either, according to the available AFAD-sourced reporting.
Background
Turkey's southern and southwestern coasts, including the stretch between Antalya and Muğla, sit near tectonically active zones of the eastern Mediterranean and routinely register numerous small earthquakes that are rarely felt or cause no damage. Both AFAD and Kandilli publish continuously updated lists of detected tremors, which Turkish news outlets compile into real-time "did an earthquake just happen" roundups that readers search for by city name, explaining why figures tied to Antalya and nearby Muğla are often mixed together in headlines and search results.
Questions
- Did a magnitude 3.8 earthquake strike off Antalya on October 21, 2026?
- No. AFAD's data shows the strongest tremor near Antalya that day was a magnitude 2.8 quake near the Aksu district. The magnitude 3.8 earthquake widely reported in the same period struck the Mediterranean off Datça, in Muğla province, on October 19, 2026.
- Was there any damage or were there injuries from the Antalya-area earthquakes?
- No. AFAD-sourced reports from gzt.com and Reflex Haber state that no adverse effects or damage were recorded after the October 21 tremors, including the magnitude 2.8 Aksu quake.
- What was the largest earthquake recorded near Antalya on October 21, 2026?
- According to AFAD, the largest was a magnitude 2.8 earthquake near the Aksu district at 17:32 local time, at a depth of about 7 kilometres.
- Why do AFAD and Kandilli sometimes report different magnitudes for the same quake?
- AFAD and Boğaziçi University's Kandilli Observatory operate separate seismic networks and calculation methods, which can produce different magnitude, depth and epicentre estimates for the same event, as seen in their differing readings for a tremor near Crete on October 21.
- Where exactly was the magnitude 3.8 Mediterranean earthquake?
- AFAD placed it in the Mediterranean Sea, 290.53 kilometres from the Datça district of Muğla province, at a depth of 7 kilometres, on October 19, 2026 at 17:30 local time.
