A shallow magnitude 3.1 earthquake was reported early morning near William Creek, South Australia, Australia.According to Geoscience Australia (GeoAu), the quake hit on Tuesday, September 23rd, 2025, at 4:47 am local time at a shallow depth of 6.3 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.Our monitoring service identified a second report from the citizen-seismograph network of RaspberryShake which listed the quake at magnitude 3.1 as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.1.According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In William Creek (pop. 31, 22 miles away), the quake was probably not felt.Earthquake data: Date & time: Sep 23, 2025 05:17 am (GMT +9:30) local time (22 Sep 2025 19:47 GMT)Magnitude: 3.0Depth: 10.07 kmEpicenter latitude / longitude: 28.59°S / 136.27°E (South Australia, Australia)Primary data source: GeoAu
