An earthquake of magnitude 4.2 occurred only 20 minutes ago 69 km southwest of Kos, Greece, the National Observatory of Athens (NOA) reported.
The quake hit at an intermediate depth of 113.1 km beneath the epicenter near Kos, Dodecanese, South Aegean, Greece, in the evening on Wednesday, May 18th, 2022, at 8:21 pm local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the Kandilli Oservatory and Earthquake Research Institute in Istanbul (KOERI-RETMC), which listed it as a magnitude 4.1 earthquake. Other agencies reporting the same quake include the citizen-seismograph network of RaspberryShake at magnitude 4.4, the European-Mediterranean Seismological Centre (EMSC) at magnitude 4.1, and the German Research Centre for Geosciences (GFZ) at magnitude 4.1.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Mandraki (pop. 680) located 38 km from the epicenter, Kefalos (pop. 2,500) 39 km away, Astypalaia (pop. 1,100) 41 km away, Antimacheia (pop. 2,300) 52 km away, Pyli (pop. 2,400) 58 km away, Kalymnos (pop. 12,300) 62 km away, and Kos (pop. 19,200) 69 km away. In Bodrum (pop. 39,300, 90 km away), the quake was probably not felt.

If you felt this quake (or if you were near the epicenter), please share your experience and submit a short "I felt it" report! Other users would love to hear about it!
If you did NOT feel the quake although you were in the area, please report it! Your contribution is valuable to earthquake science, seismic hazard analysis and mitigation efforts. You can use your device location or the map to indicate where you were during the earthquake. Thank you!

Data for the same earthquake reported by different agencies

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.
