Light earthquake of magnitude 4.2 just reported 3 km southwest of Kamarai, Greece4.2 quake 6 Jan 3:14 am (GMT +2)
An earthquake of magnitude 4.2 occurred early morning on Wednesday 6 January 2021 at 3:14 am local time near Kamarai, Achaea, West Greece, Greece, as reported by the European-Mediterranean Seismological Centre (EMSC).
According to preliminary data, the quake was located at a very shallow depth of 2 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 should have been widely felt by almost everyone in the area of the epicenter. It might have caused light to moderate damage.
Moderate shaking probably occurred in Kamarai (pop. 1,200) located 3 km from the epicenter.
In Doukanaiika (pop. 31) located 4 km from the epicenter, Longos (pop. 660) 5 km away, Mageiras (pop. 55) 5 km away, Selianitika (pop. 900) 5 km away, and Aigio (pop. 20,400) 11 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Rio (pop. 4,700) located 16 km from the epicenter, Nafpaktos (pop. 13,400) 17 km away, and Patrai (pop. 168,000) 21 km away.
