Moderate earthquake of magnitude 4.0 just reported 62 km northwest of Berna, Switzerland

4.0 quake 22 Mar 3:50 pm (GMT +1)
A very shallow magnitude 4.0 earthquake was reported early afternoon near Berna, Bern-Mittelland District, Bern, Switzerland.
According to the Swiss Seismological Service (SED), the quake hit on Wednesday, March 22nd, 2023, at 3:50 pm local time at a very shallow depth of 5.2 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 4.4 earthquake. A third agency, the German Research Centre for Geosciences (GFZ), reported the same quake at magnitude 4.4.
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 Audincourt (pop. 15,600) located 13 km from the epicenter, Porrentruy (pop. 6,500) 14 km away, Montbeliard (pop. 28,900) 18 km away, Belfort (pop. 54,600) 31 km away, and La Chaux de Fonds (pop. 36,800) 31 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Bienne (pop. 48,600) located 36 km from the epicenter, granshan (pop. 15,900) 42 km away, Basel (pop. 164,500) 54 km away, Berna (pop. 121,600) 62 km away, and Köniz (pop. 37,200) 63 km away.
