People likely experienced weak shaking there. Several smaller towns and villages are located closer to the epicenter and might have experienced stronger shaking. In the capital of the Northern Mariana Islands, Saipan, 306 km (190 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(*)RegionCountry96 km (59 mi)E of epicenterUmatac Village(pop: 903)III: WeakUmatac Guam97 km (60 mi)E of epicenterApra Harbor(pop: 2,930)III: WeakSanta Rita Municipality Guam106 km (66 mi)E of epicenterTalofofo Village(pop: 3,220)III: WeakTalofofo Municipality Guam108 km (67 mi)E of epicenterHagatna(pop: 1,050)III: WeakHagatna Guam112 km (69 mi)E of epicenterTamuning-Tumon-Harmon Village(pop: 19,700)III: WeakTamuning Guam113 km (70 mi)E of epicenterMangilao Village(pop: 15,200)III: WeakMangilao Guam119 km (74 mi)E of epicenterDededo Village(pop: 44,900)III: WeakDededo Guam124 km (77 mi)E of epicenterYigo Village(pop: 20,500)III: WeakYigo Municipality Guam178 km (110 mi)NE of epicenterSongsong(pop: 593)III: WeakRota Northern Mariana Islands276 km (172 mi)NE of epicenterSan Jose(pop: 15,000)II: Very weakTinian Municipality Northern Mariana Islands306 km (190 mi)NE of epicenterSaipan(pop: 48,200)II: Very weakSaipan Northern Mariana Islands523 km (325 mi)S of epicenterFaraulep Village(pop: 221)II: Very weakFaraulep Municipality, State of Yap Micronesia525 km (326 mi)SW of epicenterFais(pop: 215)II: Very weakState of Yap Micronesia533 km (331 mi)NE of epicenterPatik Camp(pop: 15)II: Very weakAlamagan Island, Northern Islands Northern Mariana Islands583 km (362 mi)N of epicenterPagan Village(pop: 50)II: Very weakPagan Island, Northern Islands Northern Mariana IslandsNotes:(*) 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 16 km2 (6 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 7 km (4 mi).[More info]Recorded aftershocks, latest first (0 quake)Feb 23, 2026 03:16 am (Universal Time)14 minutes ago5.210 km0 km - This quakeSouth of Mariana IslandsMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake14 minutes agoFeb 23, 2026 03:16 GMT / Feb 23, 2026 03:16 am (Universal Time)Lat / Lng: 13.239 / 143.782: South of Mariana IslandsSource: GFZDetail info | You felt it? - Report it!',5.2,52, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',13.239,143.782,'14 minutes ago: Mag. 5.2, South of Mariana Islands','Earthquake: Mag 5.2 / 10 km (6.2 mi) depth14 minutes agoFeb 23, 2026 03:16 GMT / Feb 23, 2026 03:16 am (Universal Time)Lat / Lng: 13.239 / 143.782: South of Mariana IslandsSource: 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)})(); })(); (async function(){while(typeof mkRequest=="undefined")await new Promise(r=>setTimeout(r,500));mkRequest("https://server2.allquakes.com/api/getPrevious.php?quakeId=22745113","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.
