Moderate magnitude 4.2 earthquake 48 km northwest of Athens, Greece

4.2 earthquake April 10 05:12 (GMT +3)

4.2 earthquake April 10 05:12 (GMT +3)

A magnitude 4.2 earthquake near Athens, Nomarchía Athínas, Attica, Greece, was reported just 12 minutes ago by the National Observatory of Athens (NOA), considered the main national agency that monitors seismic activity in Greece. The earthquake occurred at a very shallow depth of 5 km below the epicenter early in the morning of Sunday, April 10, 2022, at 5:12 a.m. local time. 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 as other agencies release their report.
Our monitoring service identified a second report from the German Research Center for Geosciences (GFZ) which listed the quake at magnitude 4.3. Other agencies reporting the same earthquake include the RaspberryShake Citizen Seismograph Network at magnitude 4.7 and the European-Mediterranean Seismological Center (EMSC) at magnitude 4.2.
Based on preliminary seismic data, the quake was likely felt by many people in the epicenter area. It must not have caused significant damage, other than objects falling off shelves, glass breaking, etc.
In Kallithea (700 inhab.) located 5 km from the epicenter, and in Thebes (22,000 inhab.) 6 km away, the earthquake should have been felt as slight tremors.
Weak tremors could have been felt at Chalcis (pop. 59,100) located 25 km from the epicenter, Acharnes (pop. 99,300) at 40 km, Petroúpolis (pop. 59,000) at 41 km and Peristeri (pop. 140,000) at 43 km.
Other cities or towns near the epicenter where the quake could have been felt as a very weak tremor include Nikaia (pop. 89,400) located 46 km from the epicenter, Piraeus (pop. 163,700) at 48 km, Athens (pop. 664,000) at 48 km and Kallithea (pop. 100,600) at 50 km.

If you felt this earthquake (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 tremor although you’re around, thank you for reporting it! Your input is valuable to earthquake science, earthquake hazard analysis, and mitigation efforts. You can use your device 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.
