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 2 km2 (1 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)Aug 23, 2026 05:11 am (Universal Time)24 minutes ago4.287 km0 km - This quakeIndonesia: Minahassa Peninsula, SulawesiMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake24 minutes agoAug 23, 2026 05:11 GMT / Aug 23, 2026 05:11 am (Universal Time)Lat / Lng: -0.04 / 120.37: Indonesia: Minahassa Peninsula, SulawesiSource: BMKGOther sources: RaspberryShake: 4.2 / 87 km, EMSC: 4.2 / 87 kmDetail info | You felt it? - Report it!',4.2,42, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',-0.04,120.37,'24 minutes ago: Mag. 4.2, Indonesia: Minahassa Peninsula, Sulawesi','Earthquake: Mag 4.2 / 87 km (54 mi) depth24 minutes agoAug 23, 2026 05:11 GMT / Aug 23, 2026 05:11 am (Universal Time)Lat / Lng: -0.04 / 120.37: Indonesia: Minahassa Peninsula, SulawesiSource: BMKGOther sources: RaspberryShake: 4.2 / 87 km, EMSC: 4.2 / 87 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=23305198","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)})();]]>Try our free app!Android | iOS versionSupport Us – Help Us Enhance Our Services!We’re passionate about delivering the latest volcano and earthquake data from around the globe — just for you.
