An earthquake of magnitude 3.7 occurred in the morning on Sunday, May 3rd, 2026, at 10:54 am local time near Quorn, Flinders Ranges, South Australia, Australia, as reported by Geoscience Australia (GeoAu).According to preliminary data, the quake was located at a very shallow depth of 3.8 miles. 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 3.7 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.7.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 Hawker (pop. 400) located 8 miles from the epicenter.Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Barndioota (pop. 10) located 16 miles from the epicenter, and Cradock (pop. 31) 18 miles away. In Quorn (pop. 1,200, 46 miles away), the quake was probably not felt.Earthquake data: Date & time: May 3, 2026 11:24 am (Adelaide time) local time (3 May 2026 01:54 GMT)Magnitude: 3.7Depth: 6.07 kmEpicenter latitude / longitude: 31.83°S / 138.53°E (Flinders Ranges, South Australia, Australia)Primary data source: GeoAu
