People likely experienced weak shaking there. In the capital of Svalbard and Jan Mayen, Longyearbyen, 176 km (109 mi) away from the epicenter, the earthquake was probably felt as very weak shaking.The following table shows some of the places that might have been affected (or not) by the shaking.DistancePlaceMax. shaking intensity(*)RegionCountry139 km (86 mi)NE of epicenterBarentsburg(pop: 455)III: WeakSpitsbergen, Svalbard Svalbard & Jan Mayen169 km (105 mi)NE of epicenterNy-Ålesund(pop: 35)II: Very weakSpitsbergen, Svalbard Svalbard & Jan Mayen176 km (109 mi)NE of epicenterLongyearbyen(pop: 2,370)II: Very weakSpitsbergen, Svalbard Svalbard & Jan Mayen190 km (118 mi)E of epicenterSveagruva(pop: 300)II: Very weakSpitsbergen, Svalbard Svalbard & Jan MayenNotes:(*) Shaking intensity according to the Modified Mercalli Intensity Scale (MMI) and estimated using seismic models.User-reports for this quakeThere are no user reports for this quake yet.If you felt it, be the first to report it!Get the Android appCompare Quake DataData for the same earthquake as reported by different agenciesThe more agencies report about the same quake and post similar data, the more confidence you can have in the data.

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 6 km2 (2 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 4 km (3 mi).[More info]Recorded aftershocks, latest first (0 quake)Aug 17, 2026 07:51 pm (Universal Time)14 minutes ago4.810 km0 km - This quakeSvalbard & Jan Mayen: Svalbard RegionMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake14 minutes agoAug 17, 2026 19:51 GMT / Aug 17, 2026 07:51 pm (Universal Time)Lat / Lng: 77.539 / 8.846: Svalbard & Jan Mayen: Svalbard RegionSource: GFZDetail info | You felt it? - Report it!',4.8,48, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',77.539,8.846,'14 minutes ago: Mag. 4.8, Svalbard & Jan Mayen: Svalbard Region','Earthquake: Mag 4.8 / 10 km (6.2 mi) depth14 minutes agoAug 17, 2026 19:51 GMT / Aug 17, 2026 07:51 pm (Universal Time)Lat / Lng: 77.539 / 8.846: Svalbard & Jan Mayen: Svalbard RegionSource: GFZDetail info | 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)})(); })(); (function(){let done=false;async function loadPrevious(){if(done)return;done=true;while(typeof mkRequest=="undefined")await new Promise(r=>setTimeout(r,500));mkRequest("https://server2.allquakes.com/api/getPrevious.php?quakeId=23285552","get","",function(httpObj){let r=httpObj.responseText,d=document;if(""!=r&&200==httpObj.status){let o=JSON.parse(r);if(!o){let s=d.getElementById("olderQuakesSection");if(s)s.remove();return};let table=d.getElementById("qTableOlder");if(!table)return;table.innerHTML+=o.tableRows,qTableOlder.alternateBg();let ph=d.getElementById("placeholder_largestQText");if(ph)ph.innerHTML=o.html;let wrap=d.getElementById("sectionPreviousCWrap");if(wrap)wrap.style.display="";eval(o.js)}})}let d=document,target=d.getElementById("sectionPreviousCWrap")||d.getElementById("placeholder_largestQText")||d.getElementById("qTableOlder");if(!target||!("IntersectionObserver" in window)){loadPrevious();return}let obs=new IntersectionObserver(function(entries){if(entries.some(e=>e.isIntersecting)){obs.disconnect();loadPrevious()}},{rootMargin:"300px 0px"});obs.observe(target)})();]]>Try our free app!Android | iOS versionSupport Us – Help Us Enhance Our Services!We’re passionate about delivering the latest volcano and earthquake data from around the globe — just for you.
