Moderate magnitude 4.2 quake hits 1 km northeast of Thebes, Greece early morning
4.2 quake 11 Jul 3:00 am (GMT +3)
4.2 quake 11 Jul 3:00 am (GMT +3)
A magnitude 4.2 earthquake near Thebes, Voiotía, Central Greece, Greece, was reported only 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 beneath the epicenter early morning on Sunday 11 July 2021 at 3:00 am 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 4.2 earthquake as well. Other agencies reporting the same quake include the German Research Centre for Geosciences (GFZ) at magnitude 4.4, and the European-Mediterranean Seismological Centre (EMSC) at magnitude 4.4.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Thebes (pop. 22,000) located 1 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Chalcis (pop. 59,100) located 28 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Petroúpolis (pop. 59,000) located 45 km from the epicenter, Acharnes (pop. 99,300) 45 km away, Peristeri (pop. 140,000) 47 km away, Keratsini (pop. 77,100) 48 km away, Nikaia (pop. 89,400) 49 km away, Piraeus (pop. 163,700) 51 km away, Athens (pop. 664,000) 52 km away, and Lamia (pop. 52,000) 101 km away.
