The earthquake occurred at a moderately shallow depth of 35. km beneath the epicenter in the morning on Sunday, August 16th, 2026, at 8:53 am local time. 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.Our monitoring service identified a second report from the German Research Centre for Geosciences (GFZ) which listed the quake at magnitude 5.2 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 Colonia (pop. 7,400) located 39 km from the epicenter.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.

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)Aug 16, 2026 08:53 am (GMT +10)10 minutes ago5.235 km0 km - This quakeState OF Yap, MicronesiaMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake10 minutes agoAug 15, 2026 22:53 GMT / Aug 16, 2026 08:53 am (GMT +10)Lat / Lng: 9.6547 / 138.4501: State OF Yap, MicronesiaSource: EMSCOther sources: GFZ: 5.2 / 86 kmDetail info | You felt it? - Report it!',5.2,52, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',9.6547,138.4501,'10 minutes ago: Mag. 5.2, State OF Yap, Micronesia','Earthquake: Mag 5.2 / 35 km (22 mi) depth10 minutes agoAug 15, 2026 22:53 GMT / Aug 16, 2026 08:53 am (GMT +10)Lat / Lng: 9.6547 / 138.4501: State OF Yap, MicronesiaSource: EMSCOther sources: GFZ: 5.2 / 86 kmDetail 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=23277006","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)})();]]>Sources: VolcanoDiscovery / VolcanoAdventures and other sources as noted.Use of material: Most text and images on our websites are owned by us.
