The German Research Centre for Geosciences (GFZ) reported a magnitude 4.6 quake in Poland near Glogow, Głogów County, Lower Silesia, only 10 minutes ago. The earthquake hit early evening on Thursday, April 7th, 2022, at 6:58 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 the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 4.6 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 4.3.
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 Polkowice (pop. 21,600) located 5 km from the epicenter, Glogow (pop. 68,500) 14 km away, and Lubin (pop. 77,500) 17 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Legnica (pop. 106,000) located 37 km from the epicenter, Nowa Sol (pop. 40,400) 40 km away, Leszno (pop. 63,600) 46 km away, and Bolesławiec (pop. 40,700) 48 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Jelenia Gora (pop. 87,300) located 76 km from the epicenter, and Breslau (pop. 634,900) 81 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
