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 1 km2 (0 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)Jul 19, 2026 10:40 am (GMT +9)28 minutes ago4.1460 km0 km - This quake281 km N of Ama, JapanMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake28 minutes agoJul 19, 2026 01:40 GMT / Jul 19, 2026 10:40 am (GMT +9)Lat / Lng: 38.6177 / 133.4192: 281 km N of Ama, JapanSource: USGSOther sources: EMSC: 4.1 / 460 km, NIED: 5.1 / 485 kmDetail info | You felt it? - Report it!',4.1,41, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',38.6177,133.4192,'28 minutes ago: Mag. 4.1, 281 km N of Ama, Japan','Earthquake: Mag 4.1 / 460 km (286 mi) depth28 minutes agoJul 19, 2026 01:40 GMT / Jul 19, 2026 10:40 am (GMT +9)Lat / Lng: 38.6177 / 133.4192: 281 km N of Ama, JapanSource: USGSOther sources: EMSC: 4.1 / 460 km, NIED: 5.1 / 485 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)})(); })(); (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=23197188","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)})();]]>Sources: VolcanoDiscovery / VolcanoAdventures and other sources as noted.Use of material: Most text and images on our websites are owned by us.
