Small magnitude 3.3 earthquake 18 km northwest of Legnica, Poland
3.3 quake 17 Aug 12:29 pm (GMT +2)

A shallow magnitude 3.3 earthquake was reported around noon near Legnica, Lower Silesia, Poland.
According to the German Research Centre for Geosciences (GFZ), the quake hit on Thursday, August 17th, 2023, at 12:29 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.
A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 3.3 earthquake as well.
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 Chojnow (pop. 14,200) located 4 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Legnica (pop. 106,000) located 18 km from the epicenter, Lubin (pop. 77,500) 20 km away, Goldberg (pop. 16,600) 21 km away, Polkowice (pop. 21,600) 23 km away, Bolesławiec (pop. 40,700) 27 km away, Jawor (pop. 23,900) 33 km away, and Glogow (pop. 68,500) 40 km away. In Breslau (pop. 634,900, 79 km away), the quake was probably not felt.
