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 7, 2026 06:42 pm (Mexico_City)23 minutes ago4.097 km0 km - This quakeMexico: 12 km Al SUROESTE De MATIAS ROMERO, OAXMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 26 years and our earthquake archive back to 1900, there are about 1,600 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.02 quakes per year (or 1 quake every 62.5 years)Mag. 6 or higher: 0.1 quakes per year (or 1 quake every 9.7 years)Mag. 5 or higher: 1.31 quakes per yearMag. 4 or higher: 273 quakes per year (or 22.8 quakes per month)Mag. 3 or higher: 1,600 quakes per year (or 4.3 quakes per day)Mag. 2 or higher: 1,600 quakes per year (or 4.3 quakes per day)The area where this quake occurred has a very high level of seismic activity. It has had at least 2 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 60 to 65 years.Number of quakes per yearPrevious quakes in the same area of this earthquake23 minutes agoJul 8, 2026 00:42 GMT / Jul 7, 2026 06:42 pm (Mexico_City time)Lat / Lng: 16.795 / -95.118: Mexico: 12 km Al SUROESTE De MATIAS ROMERO, OAXSource: SSNDetail info | You felt it? - Report it!',4.0,40, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',16.795,-95.118,'23 minutes ago: Mag. 4.0, Mexico: 12 km Al SUROESTE De MATIAS ROMERO, OAX','Earthquake: Mag 4.0 / 97 km (61 mi) depth23 minutes agoJul 8, 2026 00:42 GMT / Jul 7, 2026 06:42 pm (Mexico_City time)Lat / Lng: 16.795 / -95.118: Mexico: 12 km Al SUROESTE De MATIAS ROMERO, OAXSource: SSNDetail 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://server1.allquakes.com/api/getPrevious.php?quakeId=23168386","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.
