4.4 quake 21 Oct 11:12 am (GMT +3)

An earthquake of magnitude 4.4 occurred in the morning on Thursday, October 21st, 2021, at 11:12 am local time near Heraklion, Crete, Greece, as reported by the National Observatory of Athens (NOA).
According to preliminary data, the quake was located at a very shallow depth of 5 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 4.2 earthquake. Other agencies reporting the same quake include the German Research Centre for Geosciences (GFZ) at magnitude 4.5, and the European-Mediterranean Seismological Centre (EMSC) 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 Arkalochori (pop. 3,500) located 9 km from the epicenter, and Arkalochori (pop. 3,500) 9 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Ano Archanes (pop. 3,900) located 20 km from the epicenter, Heraklion (pop. 137,200) 31 km away, Néa Alikarnassos (pop. 12,900) 31 km away, Gazi (pop. 12,600) 34 km away, Mires (pop. 6,400) 35 km away, Agios Nikolaos (pop. 11,400) 43 km away, and Ierapetra (pop. 12,400) 44 km away.
