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 8 km2 (3 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 5 km (3 mi).[More info]Recorded aftershocks, latest first (0 quake)Jun 9, 2025 04:55 pm (Universal Time)7 minutes ago4.956 km0 km - This quakeJava, IndonesiaMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake7 minutes agoJun 9, 2025 16:55 GMT / Jun 9, 2025 04:55 pm (Universal Time)Lat / Lng: -8.03 / 108.73: Java, IndonesiaSource: BMKGDetail info | You felt it? - Report it!',4.9,49, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',-8.03,108.73,'7 minutes ago: Mag. 4.9, Java, Indonesia','Earthquake: Mag 4.9 / 56 km (35 mi) depth7 minutes agoJun 9, 2025 16:55 GMT / Jun 9, 2025 04:55 pm (Universal Time)Lat / Lng: -8.03 / 108.73: Java, IndonesiaSource: BMKGDetail 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=21850261","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)}})})();]]>Sources: VolcanoDiscovery / VolcanoAdventures and other sources as noted.Use of material: Most text and images on our websites are owned by us.
