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 shaking171–71 km (44–44 mi)71 km (44 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (1 in total) could be used for geographic statistics.I 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)Sep 10, 2025 05:57 pm (GMT -6)5 minutes ago4.110 km0 km - This quakeUintah County, 45 mi NE of Duchesne, Duchesne County, Utah, United StatesMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake5 minutes ago reported feltSep 10, 2025 23:57 GMT / Sep 10, 2025 05:57 pm (GMT -6)Lat / Lng: 40.4248 / -109.6296: 6 km SSW of Maeser, UtahSource: USGSOther sources: EMSC: 4.1 / 10 kmDetail info | Read user reports | You felt it? - Report it!',4.1,41, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',40.4248,-109.6296,'5 minutes ago: Mag. 4.1, 6 km SSW of Maeser, Utah','Earthquake: Mag 4.1 / 10 km (6.2 mi) depth5 minutes ago reported feltSep 10, 2025 23:57 GMT / Sep 10, 2025 05:57 pm (GMT -6)Lat / Lng: 40.4248 / -109.6296: 6 km SSW of Maeser, UtahSource: USGSOther sources: EMSC: 4.1 / 10 kmDetail info | Read user reports | You felt it? - Report it!','default'); // this will be local to this table obj function putQuakeOnMap(id,lat,lon,time,title,html,mag,zIndex) { qTableOlder.putQuakeOnMap(id,lat,lon,time,title,html,mag,zIndex); } map2.circleScale=0.5;qTableOlder.usePalette=1;qTableOlder.startVal=qTableOlder.referenceTime-(80*365.25*86400);qTableOlder.endVal=qTableOlder.referenceTime; qTableOlder.assignMap(map2); (async function(){await new Promise(r => setTimeout(r,4000));map2.map.setZoom(7)})(); })(); (async function(){while(typeof mkRequest=="undefined")await new Promise(r=>setTimeout(r,500));mkRequest("https://server2.allquakes.com/api/getPrevious.php?quakeId=22155066","get","",function(httpObj){let r=httpObj.responseText,d=document;if(""!=r&&200==httpObj.status){let o=JSON.parse(r);if(!o){d.getElementById("olderQuakesSection").remove();return};let table=d.getElementById("qTableOlder");table.innerHTML+=o.tableRows,qTableOlder.alternateBg(),d.getElementById("placeholder_largestQText").innerHTML=o.html,d.getElementById("sectionPreviousCWrap").style.display="",eval(o.js)}})})();]]>
