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)Nov 18, 2025 09:57 pm (Universal Time)2 minutes ago4.199 km0 km - This quakeKenai Peninsula Borough, AlaskaMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake2 minutes agoNov 18, 2025 21:57 GMT / Nov 18, 2025 09:57 pm (Universal Time)Lat / Lng: 59.89129 / -152.81911: 56 km WNW of Anchor Point, AlaskaSource: USGSDetail info | You felt it? - Report it!',4.1,41, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',59.89129,-152.81911,'2 minutes ago: Mag. 4.1, 56 km WNW of Anchor Point, Alaska','Earthquake: Mag 4.1 / 99 km (62 mi) depth2 minutes agoNov 18, 2025 21:57 GMT / Nov 18, 2025 09:57 pm (Universal Time)Lat / Lng: 59.89129 / -152.81911: 56 km WNW of Anchor Point, AlaskaSource: USGSDetail 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)})(); })(); (async function(){while(typeof mkRequest=="undefined")await new Promise(r=>setTimeout(r,500));mkRequest("https://server2.allquakes.com/api/getPrevious.php?quakeId=22409019","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)}})})();]]>Support Us – Help Us Enhance Our Services!We’re passionate about delivering the latest volcano and earthquake data from around the globe — just for you.
