Moderate magnitude 4.0 earthquake at 14 km depth7 Aug 23:57 UTC: First to report: VolcanoDiscovery after 3 minutes.7 Aug 23:58: Now using data updates from EMSC7 Aug 23:58: Now using data updates from USGSUpdate Sat, 8 Aug 2026, 00:00Moderate magnitude 4.0 quake hits 47 miles southeast of Monroe, Utah, United States in the afternoonAn earthquake of magnitude 4.0 occurred in the afternoon on Friday, August 7th, 2026, at 5:54 pm local time near Monroe, Sevier County, Utah, USA, as reported by the United States Geological Survey.According to preliminary data, the quake was located at a shallow depth of 8.4 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 European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.0 earthquake as well.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 Bicknell (pop. 330) located 12 miles from the epicenter, and Loa (pop. 590) 18 miles away.Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Monroe (pop. 2,300) located 47 miles from the epicenter, Richfield (pop. 7,600) 52 miles away, Aurora (pop. 1000) 57 miles away, Salina (pop. 2,500) 58 miles away, and Panguitch (pop. 1,500) 58 miles away.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 7, 2026 23:54:21 UTC - Local time at epicenterFriday, Aug 7, 2026, at 05:54 pm (America/Denver GMT -6)StatusconfirmedMagnitude3.97Depth13.5 kmEpicenter latitude / longitude38.18°N / 111.4803°WWayne County, Utah, United StatesSeismic antipode38.18°S / 68.5197°EQuality6 seismic stationsShaking intensityIV Light shaking near epicenterFelt23 reportsPrimary data sourceUSGS (United States Geological Survey)Nearest volcanoMarkagunt Plateau (124 km / 77 mi)Weather at epicenter at time of quakeBroken Clouds 37.9°C (100 F), humidity: 13%, wind: 1 m/s (3 kts) from SEEstimated seismic energy released6.3 x 1010 joules (17.5 megawatt hours, equivalent to 15.1 tons of TNT) | equivalent to ONE quake of magnitude 4.0 | about seismic energy18 minutes ago reported feltAug 7, 2026 23:54 GMT / Aug 7, 2026 05:54 pm (Denver time)Lat / Lng: 38.18 / -111.48033: 11 km S of Teasdale, UtahSource: USGSOther sources: EMSC: 4.0 / 14 kmDetail info | Read user reports | You felt it? - Report it!';storedMarkers.push(['quake-23253443',38.18000,-111.48033,'18 minutes ago: Mag. 4.0, 11 km S of Teasdale, Utah',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)Ground accelleration map for this quakeMap of estimated ground accelleration (source:USGS)Most recent quakes Top 20 past 24 hrs Quakes in the US UtahNearby placesThe closest larger town where the quake might have been felt is Richfield, a town with 7,600 inhabitants in the United States, in 84 km (52 mi) distance northwest of the epicenter.

It is commonly measured on the so-called Modified Mercalli Intensity Scale (MMI) ranging from 1 (not felt) to 10 (extreme shaking), and given in Roman numerals as I,II,...IX, X, and often displayed with color codes ranging from light blue to dark red.Earthquake intensity depends mainly on the magnitude and depth of the quake as well as the distance from the epicenter: The further away, the less shaking intensity occurs.Read more about the MMI scale!Number of reports by intensityShaking intensityNumber of reportsMin-Max distance from epicenter (*)Average distance (*)II: Very weak shaking4250–252 km (155–156 mi)251 km (156 mi)III: Weak shaking11.4–1.4 km (0.9–0.9 mi)1.4 km (0.9 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (23 in total) could be used for geographic statistics.Get the Android appI didn't feel itI felt this quakeIf you were near the epicenter and felt it, please share your experience and submit a short "I felt it" report!

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 7, 2026 05:54 pm (Denver)18 minutes ago - felt4.014 km0 km - This quakeWayne County, 47 mi SE of Monroe, Sevier County, Utah, United StatesMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 56 years and our earthquake archive back to 1900, there are about 224 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 5 or higher: 0.03 quakes per year (or 1 quake every 38.5 years)Mag. 4 or higher: 0.31 quakes per year (or 1 quake every 3.3 years)Mag. 3 or higher: 2.7 quakes per yearMag. 2 or higher: 29.1 quakes per yearMag. 1 or higher: 194 quakes per year (or 16.2 quakes per month)The area where this quake occurred has relatively few earthquakes. However, It has had at least 2 quakes above magnitude 5 since 1970, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 25 to 30 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
