An earthquake of magnitude 4.0 occurred in the morning on Wednesday, April 22nd, 2026, at 10:24 am local time near Tonopah, Nye County, Nevada, USA, as reported by the United States Geological Survey.According to preliminary data, the quake was located at a shallow depth of 9.9 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 Incorporated Research Institutions for Seismology (IRIS) which listed the quake at magnitude 4.0 as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 4.0.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 Tonopah (pop. 2,500) located 13 miles from the epicenter.Earthquake data: Date & time: Apr 22, 2026 10:24 am (GMT -7) local time (22 Apr 2026 17:24 GMT)Magnitude: 4.0Depth: 15.98 kmEpicenter latitude / longitude: 37.89°N / 117.3°W (Esmeralda County, Nevada, United States)Primary data source: USGS
