It is commonly measured on the so-called Modified Mercalli Intensity Scale (MMI) ranging from 1 (not felt) to 10 (extreme shaking), and given in Roman numerals as I,II,...IX, X, and often displayed with color codes ranging from light blue to dark red.Earthquake intensity depends mainly on the magnitude and depth of the quake as well as the distance from the epicenter: The further away, the less shaking intensity occurs.Read more about the MMI scale!Number of reports by intensityShaking intensityNumber of reportsMin-Max distance from epicenter (*)Average distance (*)IV: Light shaking1247–247 km (153–153 mi)247 km (153 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (1 in total) could be used for geographic statistics.Get the Android appI didn't feel itI felt this quakeIf you were near the epicenter and felt it, please share your experience and submit a short "I felt it" report!

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 5 km2 (2 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 4 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Aug 21, 2026 06:26 pm (Santiago)8 minutes ago4.7139 km0 km - This quakeProvincia de Antofagasta, Region de Antofagasta, ChileMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake8 minutes ago reported feltAug 21, 2026 22:26 GMT / Aug 21, 2026 06:26 pm (Santiago time)Lat / Lng: -25.501 / -69.003: Chile: 104 km Al NE De El SalvadorSource: CSNOther sources: RaspberryShake: 4.7 / 139 kmDetail info | Read user reports | You felt it? - Report it!',4.7,47, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',-25.501,-69.003,'8 minutes ago: Mag. 4.7, Chile: 104 km Al NE De El Salvador','Earthquake: Mag 4.7 / 139 km (86 mi) depth8 minutes ago reported feltAug 21, 2026 22:26 GMT / Aug 21, 2026 06:26 pm (Santiago time)Lat / Lng: -25.501 / -69.003: Chile: 104 km Al NE De El SalvadorSource: CSNOther sources: RaspberryShake: 4.7 / 139 kmDetail info | Read user reports | 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=23302324","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)})();]]>
