Moderate magnitude 4.0 quake hits 35 km southeast of Perugia, Italy late at night

A shallow magnitude 4.0 earthquake was reported late at night near Perugia, Province of Perugia, Umbria, Italy.
According to the German Research Centre for Geosciences (GFZ), the quake hit on Saturday, September 20th, 2025, at 11:11 pm 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.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Giano dell'Umbria (pop. 3,400) located 4 km from the epicenter, Todi (pop. 5,600) 11 km away, Spoleto (pop. 19,300) 19 km away, Foligno (pop. 56,900) 20 km away, Bastia umbra (pop. 17,800) 27 km away, and Terni (pop. 111,200) 30 km away.
