The length of the rupture zone thus was probably around 2 km (1 mi).[More info]Recorded aftershocks, latest first (0 quake)Jul 18, 2026 04:09 am (Taipei)19 minutes ago4.124 km0 km - This quakeTaiwan: 15.2 km SSE of Hualien County HallMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake19 minutes agoJul 17, 2026 20:09 GMT / Jul 18, 2026 04:09 am (Taipei time)Lat / Lng: 23.86 / 121.67: Taiwan: 15.2 km SSE of Hualien County HallSource: CWBOther sources: RaspberryShake: 4.1 / 24 kmDetail info | You felt it? - Report it!',4.1,41, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',23.86,121.67,'19 minutes ago: Mag. 4.1, Taiwan: 15.2 km SSE of Hualien County Hall','Earthquake: Mag 4.1 / 24 km (15 mi) depth19 minutes agoJul 17, 2026 20:09 GMT / Jul 18, 2026 04:09 am (Taipei time)Lat / Lng: 23.86 / 121.67: Taiwan: 15.2 km SSE of Hualien County HallSource: CWBOther sources: RaspberryShake: 4.1 / 24 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)})(); })(); (async function(){while(typeof mkRequest=="undefined")await new Promise(r=>setTimeout(r,500));mkRequest("https://server2.allquakes.com/api/getPrevious.php?quakeId=23193906","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)}})})();]]>Sources: VolcanoDiscovery / VolcanoAdventures and other sources as noted.Use of material: Most text and images on our websites are owned by us.
