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)Jun 17, 2026 12:32 pm (GMT -4)5 minutes ago4.29.7 km0 km - This quakeOffshore Antofagasta, ChileMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake5 minutes agoJun 17, 2026 16:32 GMT / Jun 17, 2026 12:32 pm (GMT -4)Lat / Lng: -25.43 / -70.7: Offshore Antofagasta, ChileSource: EMSCDetail info | You felt it? - Report it!',4.2,42, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',-25.43,-70.7,'5 minutes ago: Mag. 4.2, Offshore Antofagasta, Chile','Earthquake: Mag 4.2 / 9.7 km (6 mi) depth5 minutes agoJun 17, 2026 16:32 GMT / Jun 17, 2026 12:32 pm (GMT -4)Lat / Lng: -25.43 / -70.7: Offshore Antofagasta, ChileSource: EMSCDetail 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=23109884","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)}})})();]]>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.
