A shallow magnitude 3.9 earthquake was reported early morning near Sibenik, Town of Šibenik, Sibenik-Knin County, Croatia.According to the German Research Centre for Geosciences (GFZ), the quake hit on Wednesday, March 4th, 2026, at 1:23 am 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 Seismological Survey of Serbia (SSS), which listed it as a magnitude 3.9 earthquake as well. A third agency, the citizen-seismograph network of RaspberryShake, reported the same quake at magnitude 3.9.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 Siverić (pop. 500) located 1 km from the epicenter, Drnis (pop. 2,800) 5 km away, and Knin (pop. 8,300) 17 km away.Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Bilice (pop. 2,500) located 28 km from the epicenter, Sibenik (pop. 31,100) 30 km away, Vodice (pop. 6,600) 36 km away, Sinj (pop. 10,800) 41 km away, Solin (pop. 21,000) 45 km away, and Split (pop. 149,800) 46 km away.Earthquake data: Date & time: Mar 4, 2026 01:23 am (GMT +1) local time (4 Mar 2026 00:23 GMT)Magnitude: 3.9Depth: 10.00 kmEpicenter latitude / longitude: 43.89°N / 16.2°E (Grad Drnis, Sibenik-Knin County, Croatia)Primary data source: GFZ
