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 50 km2 (19 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 12 km (8 mi).[More info]Recorded aftershocks, latest first (0 quake)Aug 17, 2025 11:52 am (GMT +13)12 minutes ago5.710 km0 km - This quakeSouth of Tonga IslandsMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake12 minutes agoAug 16, 2025 22:52 GMT / Aug 17, 2025 11:52 am (GMT +13)Lat / Lng: -24.156 / -175.537: South of Tonga IslandsSource: GFZOther sources: RENASS: 5.4 / 10 kmDetail info | You felt it? - Report it!',5.7,57, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',-24.156,-175.537,'12 minutes ago: Mag. 5.7, South of Tonga Islands','Earthquake: Mag 5.7 / 10 km (6.2 mi) depth12 minutes agoAug 16, 2025 22:52 GMT / Aug 17, 2025 11:52 am (GMT +13)Lat / Lng: -24.156 / -175.537: South of Tonga IslandsSource: GFZOther sources: RENASS: 5.4 / 10 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)})(); })(); (async function(){while(typeof mkRequest=="undefined")await new Promise(r=>setTimeout(r,500));mkRequest("https://server2.allquakes.com/api/getPrevious.php?quakeId=22064242","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.
