Magnitude 4.5 earthquake strikes near Pesaro, Pesaro and Urbino, The Marches, Italy

4.5 quake 29 Oct 12:53 pm (GMT +2)

The German Research Centre for Geosciences (GFZ) reported a magnitude 4.5 quake in Italy near Pesaro, Pesaro and Urbino, The Marches, only 10 minutes ago. The earthquake hit around noon on Friday, October 29th, 2021, at 12:53 pm local time at a shallow depth of 10 km. 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 Italy's National Institute of Geophysics and Volcanology (INGV), which listed it as a magnitude 4.3 earthquake. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 4.9.
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 Falciraga (pop. 53) located 0 km from the epicenter, Fano (pop. 39,000) 5 km away, and Pesaro (pop. 77,200) 8 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Senigallia (pop. 30,900) located 25 km from the epicenter, Riccione (pop. 32,700) 29 km away, Rimini (pop. 118,700) 39 km away, San Marino (pop. 4,500) 42 km away, Iesi (pop. 37,000) 43 km away, and Ancona (pop. 90,000) 52 km away.
