An earthquake of magnitude 3.8 occurred early morning on Monday, April 6th, 2026, at 3:01 am local time near Vienna, Austria, as reported by Hungary's Seismological Observatory (Hungarian National Seismological Network).According to preliminary data, the quake was located 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.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 Raabs an der Thaya (pop. 810) located 12 km from the epicenter, Horn (pop. 5,500) 15 km away, and Eggenburg (pop. 3,100) 22 km away.Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Znojmo (pop. 35,300) located 30 km from the epicenter, Krems an der Donau (pop. 14,500) 43 km away, Trebic (pop. 38,800) 49 km away, Stockerau (pop. 16,300) 62 km away, Sankt Poelten (pop. 21,900) 66 km away, and Sankt Pölten (pop. 21,900) 67 km away. In Vienna (pop. 1,691,500, 84 km away), the quake was probably not felt.Earthquake data: Date & time: Apr 6, 2026 03:01 am (Vienna time) local time (6 Apr 2026 01:01 GMT)Magnitude: 3.8Depth: 10.00 kmEpicenter latitude / longitude: 48.8°N / 15.65°E (Politischer Bezirk Horn, Niederoesterreich, Austria)Primary data source: KRZO
