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 4 km2 (2 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)Dec 9, 2025 07:55 pm (GMT +13)10 minutes ago4.6379 km0 km - This quakeSouth Pacific Ocean, New ZealandMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake10 minutes agoDec 9, 2025 06:55 GMT / Dec 9, 2025 07:55 pm (GMT +13)Lat / Lng: -28.51402 / -178.18315: New ZealandSource: GEONET (NZ)Detail info | You felt it? - Report it!',4.6,46, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',-28.51402,-178.18315,'10 minutes ago: Mag. 4.6, New Zealand','Earthquake: Mag 4.6 / 379 km (235 mi) depth10 minutes agoDec 9, 2025 06:55 GMT / Dec 9, 2025 07:55 pm (GMT +13)Lat / Lng: -28.51402 / -178.18315: New ZealandSource: GEONET (NZ)Detail 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=22478819","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.
