Light 4.3 quake hits near Sitia, Lasithi, Crete, Greece

4.3 quake 22 Jan 8:57 am (GMT +2)
A shallow magnitude 4.3 earthquake was reported in the morning near Sitia, Lasithi, Crete, Greece.
According to the National Observatory of Athens (NOA), the quake hit on Friday 22 January 2021 at 8:57 am local time at a shallow depth of 10 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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.
Our monitoring service identified a second report from the Kandilli Oservatory and Earthquake Research Institute in Istanbul (KOERI-RETMC) which listed the quake at magnitude 4.4. Other agencies reporting the same quake include German Research Centre for Geosciences (GFZ) at magnitude 4.5, and European-Mediterranean Seismological Centre (EMSC) at magnitude 4.6.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Agia Marina (pop. 440) located 43 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Palekastro (pop. 1,100) located 51 km from the epicenter, Sitia (pop. 8,700) 57 km away, Karpathos (pop. 2,200) 65 km away, Elounda (pop. 2,200) 80 km away, Aghios Nicolaos (pop. 11,400) 85 km away, and Ierapetra (pop. 12,400) 96 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you’re in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.

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!
Also if you did NOT feel the quake although you were in the area, please report it! Your contribution is valuable also to earthquake science and earthquake 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.
