Moderate magnitude 4.1 earthquake at unknown depth30 Aug 05:10 UTC: First to report: USGS after 16 minutes.30 Aug 05:18: Magnitude recalculated from 3.9 to 4.1. Hypocenter depth recalculated from 5.77 to 0.00 km (from 3.6 to 0 mi). Epicenter location corrected by 10.7 km (6.7 mi) towards E.Update Sat, 30 Aug 2025, 05:12Magnitude 3.9 earthquake strikes near Elko, Elko County, Nevada, USAAn earthquake of magnitude 3.9 occurred in the evening on Friday, August 29th, 2025, at 9:54 pm local time near Elko, Elko County, Nevada, USA, as reported by the United States Geological Survey.According to preliminary data, the quake was located at a very shallow depth of 3.6 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 Incorporated Research Institutions for Seismology (IRIS), which listed it as a magnitude 3.9 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.9.Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Valmy (pop. 37) located 30 miles from the epicenter, Battle Mountain (pop. 3,600) 36 miles away, Carlin (pop. 2,300) 48 miles away, and Winnemucca (pop. 7,900) 50 miles away. In Elko (pop. 20,300, 59 miles away), the quake was probably not felt.If you were or still are in this area during the quake help others with your feedback and report it here.Download the Volcanoes & Earthquakes app and get one of the fastest seismic alerts online: Android | iOSI didn't feel itI felt this quakeEarthquake detailsDate & timeAug 30, 2025 04:54:48 UTC - Local time at epicenterFriday, Aug 29, 2025, at 09:54 pm (GMT -7)Statusconfirmed (manually revised)Magnitude4.1DepthUnknownEpicenter latitude / longitude41.1606°N / 116.6807°WElko County, Nevada, United StatesSeismic antipode41.1606°S / 63.3193°EQuality7 seismic stationsShaking intensityV Moderate shaking near epicenterFelt0 reportsPrimary data sourceUSGS (United States Geological Survey)Nearest volcanoBuffalo Valley (104 km / 65 mi)Weather at epicenter at time of quakeBroken Clouds 18.5°C (65 F), humidity: 34%, wind: 1 m/s (2 kts) from NNEEstimated seismic energy released8.9 x 1010 joules (24.8 megawatt hours, equivalent to 21.3 tons of TNT) | equivalent to ONE quake of magnitude 4.1 | about seismic energy27 minutes agoAug 30, 2025 04:54 GMT / Aug 29, 2025 09:54 pm (GMT -7)Lat / Lng: 41.1606 / -116.6807: 55 km NE of Valmy, NevadaSource: USGSOther sources: EMSC: 4.0 / 5.8 km, IRIS: 4.1 / 0 kmDetail info | You felt it? - Report it!';storedMarkers.push(['quake-22115555',41.16060,-116.68070,'27 minutes ago: Mag. 4.1, 55 km NE of Valmy, Nevada',html,'quakes-6-24.png',25,25,12,12,125]); function mkRep(id,notFelt){var nFelt=notFelt||false;var src="https://www.volcanoesandearthquakes.com/app/earthquake-report.php?quakeId="+id;if(nFelt==true){src+="¬Felt=true";}window.open(src,"","status=0,toolbar=0,location=0,directories=0,menubar=0,resizable=1,scrollbars=1,height=400,width=350");} function locationHashChanged(e){-1!=e.oldURL.indexOf("#popupMap")&&closePopup()} window.onhashchange = locationHashChanged; function comment(e){var t=e.parentNode,a=(t.dataset.id,document.getElementById("commentForm"));"none"==a.style.display?(t.appendChild(a),a.style.display="block"):a.style.display="none"}function sendComment(e){var t=e.parentNode,a=t.parentNode.dataset.id,n=document.getElementById("commentContent"),p=n.value.trim();if(p){var o="id="+a+"&quakeId="+thisQuakeId;o+="&comment="+decodeURIComponent(p),mkRequest("//reports.volcanodiscovery.com/app/eqReportComment.php","post",o,function(e){e.responseText;alert("Thank you for submitting your comment!"),t.style.display="none",n.value=""})}}function flagReport(e){var t=e.parentNode.dataset.id;if(confirm("Report this as inappropriate?")){var a="id="+t+"&quakeId="+thisQuakeId+"&flagAsInappropriate=1";mkRequest("//reports.volcanodiscovery.com/app/eqReportComment.php","post",a,function(t){var a=t.responseText;alert(a),e.style.display="none"})}}function likeReport(e){var t="id="+e.parentNode.dataset.id+"&quakeId="+thisQuakeId+"&like=1";mkRequest("//reports.volcanodiscovery.com/app/eqReportComment.php","post",t,function(t){t.responseText;e.style.opacity=.5})}]]>[smaller] [bigger]Ground shaking from this quakeMap of estimated ground shaking (source:USGS)Most recent quakes Top 20 past 24 hrs Quakes in the US NevadaNearby placesThe closest larger town where the quake might have been felt is Elko, a town with 20,000 inhabitants in the United States, in 85 km (53 mi) distance southeast of the epicenter.

When aftershocks are detected, we will update this section.What are aftershocks?Larger earthquakes (above magnitude 5 or so) such as this one are usually followed by smaller ones known as aftershocks that occur in the same area during the days, weeks, months or even years after the main shock.[More info]What about this quake?Based on its magnitude, the fault that was active during the quake likely ruptured beneath a surface area of approximately 1 km2 (0 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 2 km (1 mi).[More info]Recorded aftershocks, latest first (0 quake)Aug 29, 2025 09:54 pm (GMT -7)27 minutes ago4.10 km0 km - This quake53 mi NW of Elko, Elko County, Nevada, United StatesMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 55 years and our earthquake archive back to 1900, there are about 53 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 4 or higher: 0.13 quakes per year (or 1 quake every 7.7 years)Mag. 3 or higher: 3.8 quakes per yearMag. 2 or higher: 24.1 quakes per yearMag. 1 or higher: 46 quakes per year (or 3.9 quakes per month)The area where this quake occurred has relatively few earthquakes. However, It has had at least 7 quakes above magnitude 4 since 1970, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 5 to 10 years.Number of quakes per yearPrevious quakes in the same area of this earthquakeStrongest in 24 yearsThe earthquake was the strongest to hit this part of the United States in over 24 years.
