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 16 km2 (6 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 7 km (4 mi).[More info]Recorded aftershocks, latest first (0 quake)Aug 7, 2025 10:29 pm (GMT +7)6 minutes ago5.2100 km0 km - This quakeKota Padangsidimpuan, 35 km S of Sibolga, Kota Sibolga, North Sumatra, IndonesiaMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake6 minutes agoAug 7, 2025 15:29 GMT / Aug 7, 2025 10:29 pm (GMT +7)Lat / Lng: 1.4394 / 98.8623: Northern Sumatra, IndonesiaSource: EMSCOther sources: EMSC: 5.2 / 100 kmDetail info | You felt it? - Report it!',5.2,52, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',1.4394,98.8623,'6 minutes ago: Mag. 5.2, Northern Sumatra, Indonesia','Earthquake: Mag 5.2 / 100 km (62 mi) depth6 minutes agoAug 7, 2025 15:29 GMT / Aug 7, 2025 10:29 pm (GMT +7)Lat / Lng: 1.4394 / 98.8623: Northern Sumatra, IndonesiaSource: EMSCOther sources: EMSC: 5.2 / 100 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=22031820","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)}})})();]]>
