4.2 quake 15 km east of Patrai, Achaea, West Greece, 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 Patrai, Achaea, West Greece, Greece, as reported by the United States Geological Survey (USGS).
According to preliminary data, the quake was located at a shallow depth of 10 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 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 Mageiras (pop. 55) located 6 km from the epicenter, and Ano Kastritsi (pop. 1000) 7 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Kamarai (pop. 1,200) located 11 km from the epicenter, Aktaio (pop. 1,500) 12 km away, Rio (pop. 4,700) 12 km away, Patrai (pop. 168,000) 15 km away, Aigio (pop. 20,400) 16 km away, Ovria (pop. 5,800) 16 km away, and Nafpaktos (pop. 13,400) 18 km away.
