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 1 km2 (0 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 2 km (1 mi).[More info]Recorded aftershocks, latest first (0 quake)Jul 23, 2026 08:24 pm (GMT +9)13 minutes ago4.0175 km0 km - This quakeBanda Sea, 73 km SE of Pulau Banda Besar Island, Maluku, IndonesiaMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake13 minutes agoJul 23, 2026 11:24 GMT / Jul 23, 2026 08:24 pm (GMT +9)Lat / Lng: -5.15 / 130.19: Indonesia: Banda SeaSource: EMSCOther sources: RaspberryShake: 4.0 / 175 km, BMKG: 4.0 / 175 kmDetail info | You felt it? - Report it!',4.0,40, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',-5.15,130.19,'13 minutes ago: Mag. 4.0, Indonesia: Banda Sea','Earthquake: Mag 4.0 / 175 km (109 mi) depth13 minutes agoJul 23, 2026 11:24 GMT / Jul 23, 2026 08:24 pm (GMT +9)Lat / Lng: -5.15 / 130.19: Indonesia: Banda SeaSource: EMSCOther sources: RaspberryShake: 4.0 / 175 km, BMKG: 4.0 / 175 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=23209101","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.
