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)Oct 21, 2026 02:47 am (Universal Time)14 minutes ago4.26 km0 km - This quake393 km SW of San Jose, Provincia de San Jose, Costa RicaMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake14 minutes agoOct 21, 2026 02:47 GMT / Oct 21, 2026 02:47 am (Universal Time)Lat / Lng: 6.665 / -85.4512: Costa Rica: Off Coast OF Central AmericaSource: EMSCDetail info | You felt it? - Report it!',4.2,42, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',6.665,-85.4512,'14 minutes ago: Mag. 4.2, Costa Rica: Off Coast OF Central America','Earthquake: Mag 4.2 / 6 km (3.7 mi) depth14 minutes agoOct 21, 2026 02:47 GMT / Oct 21, 2026 02:47 am (Universal Time)Lat / Lng: 6.665 / -85.4512: Costa Rica: Off Coast OF Central AmericaSource: EMSCDetail info | You felt it? - Report it!','default'); 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://server3.allquakes.com/api/getPrevious.php?quakeId=23453120","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("olderQuakesSection");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.
