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 (*)III: Weak shaking124–24 km (14.9–14.9 mi)24 km (15 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 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 17, 2026 10:53 am (Universal Time)5 minutes ago4.267 km0 km - This quakeZamora Chinchipe, 26 km SE of Loja, Provincia de Loja, EcuadorMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake5 minutes ago reported feltOct 17, 2026 10:53 GMT / Oct 17, 2026 10:53 am (Universal Time)Lat / Lng: -4.1 / -79: Peru-Ecuador Border RegionSource: EMSCDetail info | Read user reports | You felt it? - Report it!',4.2,42, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',-4.1,-79,'5 minutes ago: Mag. 4.2, Peru-Ecuador Border Region','Earthquake: Mag 4.2 / 67 km (42 mi) depth5 minutes ago reported feltOct 17, 2026 10:53 GMT / Oct 17, 2026 10:53 am (Universal Time)Lat / Lng: -4.1 / -79: Peru-Ecuador Border RegionSource: EMSCDetail info | Read user reports | 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=23443750","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)})();]]>
