Earthquake 4.2 October 6 4:25 p.m. (GMT +3)

A shallow 4.2 magnitude earthquake was reported in the afternoon near Athens, Nomarchía Athínas, Attica, Greece.
According to the Athens National Observatory (NOA), the earthquake struck on Wednesday October 6, 2021 at 4:25 p.m. local time at a shallow depth of 10 km. Shallow earthquakes are felt more strongly than deep ones because they are closer to the surface. The exact magnitude, epicenter and depth of the quake could be revised in the coming hours or minutes, as seismologists review the data and refine their calculations, or when other agencies release their report.
Based on preliminary seismic data, the quake should not have caused significant damage, but was likely felt by many as a slight vibration in the epicenter area.
Weak tremors could have been felt at Sykamia (pop. 26) located 20 km from the epicenter.
Other towns close to the epicenter where the earthquake could have been felt as very weak tremors include Glyfada (pop. 87,300) located 78 km from the epicenter, Ilioupoli (pop. 78,200) at 83 km, Agios Dimitrios (pop. 71,300) 85 km, Kallithea (100,600 inhabitants) 88 km, Athens (664,000 inhabitants) 90 km, Piraeus (163,700 inhabitants) 91 km, Nikaia (89,400 inhabitants) 93 km , Peristeri (140,000 inhabitants) 95 km and Acharnes (99,300 inhabitants) 99 km.

If you felt this earthquake (or 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 earthquake although you are in the area, please report it! Your contribution is valuable to earthquake science, seismic risk analysis and mitigation efforts. You can use your device’s location or the map to show where you were during the earthquake. Thank you!

Data for the same earthquake reported by different agencies

Info: The more agencies report the same earthquake and publish similar data, the more confidence you can have in the data. It normally takes up to a few hours for the seismic parameters to be calculated with near optimum accuracy.
