Light magnitude 4.5 quake hits 9 km northwest of Glyfada, Greece after midnight

4.5 quake 13 Jan 12:29 am (GMT +2)
An earthquake of magnitude 4.5 occurred after midnight on Wednesday 13 January 2021 at 12:29 am local time near Glyfada, Phocis, Central Greece, Greece, as reported by the German Research Centre for Geosciences (GFZ).
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 Glyfada (pop. 480) located 9 km from the epicenter, Chania (pop. 62) 10 km away, Trizonia (pop. 64) 10 km away, Kastraki (pop. 910) 13 km away, and Lidoriki (pop. 840) 16 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Nafpaktos (pop. 13,400) located 20 km from the epicenter, Rododafni (pop. 2,600) 21 km away, Aigio (pop. 20,400) 24 km away, and Patrai (pop. 168,000) 36 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
