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 3 km2 (1 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 3 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Aug 7, 2025 03:09 am (Universal Time)28 minutes ago4.4163 km0 km - This quake159 km SSW of Hihifo, TongaMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake28 minutes agoAug 7, 2025 03:09 GMT / Aug 7, 2025 03:09 am (Universal Time)Lat / Lng: -17.2625 / -174.4211: 159 km SSW of Hihifo, TongaSource: USGSOther sources: EMSC: 4.4 / 164 kmDetail info | You felt it? - Report it!',4.4,44, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',-17.2625,-174.4211,'28 minutes ago: Mag. 4.4, 159 km SSW of Hihifo, Tonga','Earthquake: Mag 4.4 / 163 km (102 mi) depth28 minutes agoAug 7, 2025 03:09 GMT / Aug 7, 2025 03:09 am (Universal Time)Lat / Lng: -17.2625 / -174.4211: 159 km SSW of Hihifo, TongaSource: USGSOther sources: EMSC: 4.4 / 164 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=22030407","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 upgrade our services!We truly love working to bring you the latest volcano and earthquake data from around the world.
