Magnitude 4.3 earthquake strikes near Katerini, Pieria, Macedonia Centrale, Greece4.3 quake 4 Mar 8:45 pm (GMT +2)
A magnitude 4.3 earthquake near Katerini, Pieria, Macedonia Centrale, Greece, was reported only 15 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 shallow depth of 10 km beneath the epicenter in the evening on Thursday 4 March 2021 at 8:45 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.
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 Agios Dimitrios (pop. 880) located 3 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Litochoro (pop. 6,700) located 22 km from the epicenter, Katerini (pop. 53,300) 27 km away, and Véroia (pop. 44,500) 44 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Naousa (pop. 19,900) located 58 km from the epicenter, Ptolemaida (pop. 30,000) 64 km away, Kalamaria (pop. 91,600) 78 km away, Thessaloniki (pop. 354,300) 82 km away, and Sykiés (pop. 45,000) 83 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
