3.7 quake 21 Dec 12:24 am (GMT +1)

Spain's Instituto Geográfico Nacional (IGN) reported a magnitude 3.7 quake in Spain near Berga, Barcelona, Catalonia, only 8 minutes ago. The earthquake hit after midnight on Thursday, December 21st, 2023, at 12:24 am local time at a very shallow depth of 5 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.
Our monitoring service identified a second report from France's Réseau National de Surveillance Sismique (RéNaSS) which listed the quake at magnitude 4.1.
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 Toloriu (pop. 1000) located 6 km from the epicenter, and Sant Julià de Lòria (pop. 8,000) 21 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Escaldes-Engordany (pop. 15,900) located 23 km from the epicenter, Andorra la Vella (pop. 20,400) 24 km away, Encamp (pop. 11,200) 25 km away, La Massana (pop. 7,200) 28 km away, Ordino (pop. 3,100) 29 km away, Berga (pop. 17,200) 29 km away, and Canillo (pop. 3,300) 29 km away.
