A magnitude 4.2 earthquake near Amaliada, Ilia Prefecture, Western Greece, Greece, was reported only 7 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 early afternoon on Sunday 28 February 2021 at 2:26 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.5 earthquake. A third agency, the German Research Centre for Geosciences (GFZ), reported the same quake at magnitude 4.5.
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 Korithi (pop. 48) located 7 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Katastari (pop. 1,400) located 14 km from the epicenter, Gaitani (pop. 1,900) 22 km away, Zakynthos (pop. 11,500) 24 km away, Argostoli (pop. 9,800) 34 km away, and Lixouri (pop. 3,800) 38 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Gastouni (pop. 8,100) located 45 km from the epicenter, Amaliada (pop. 16,800) 56 km away, and Pýrgos (pop. 22,400) 68 km away.
