Light magnitude 4.9 earthquake 22 km south of Fokia, Greece
4.9 quake 29 Dec 10:06 am (GMT +2)
4.9 quake 29 Dec 10:06 am (GMT +2)
A shallow magnitude 4.9 earthquake was reported in the morning near Fokia, Crete, Greece.
According to the German Research Centre for Geosciences (GFZ), the quake hit on Tuesday 29 December 2020 at 10:06 am local time 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.
A second report was later issued by the Kandilli Oservatory and Earthquake Research Institute in Istanbul (KOERI-RETMC), which listed it as a magnitude 4.5 earthquake. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 4.6.
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 Vatsiana (pop. 31) located 21 km from the epicenter, Fokia (pop. 53) 22 km away, Kastri (pop. 37) 23 km away, Ampelos (pop. 10) 24 km away, and Karave (pop. 21) 24 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Tympaki (pop. 5,300) located 79 km from the epicenter, Moires (pop. 6,400) 85 km away, Rethymno (pop. 32,500) 89 km away, and Chania (pop. 53,900) 98 km away.
