People likely experienced weak shaking there. Several smaller towns and villages are located closer to the epicenter and might have experienced stronger shaking. In the capital of Iceland, Reykjavik, 237 km (147 mi) away from the epicenter, the earthquake was probably felt as very weak shaking.The following table shows some of the places that might have been affected (or not) by the shaking.DistancePlaceMax. shaking intensity(*)RegionCountry84 km (52 mi)SW of epicenterKirkjubaejarklaustur(pop: 119)III: WeakSkaftárhreppur, SouthIceland89 km (55 mi)E of epicenterHofn(pop: 1,690)III: WeakSveitarfelagid Hornafjoerdur, EastIceland134 km (84 mi)E of epicenterDjupivogur(pop: 348)II: Very weakMulathing, EastIceland138 km (86 mi)N of epicenterReykjahlið(pop: 227)II: Very weakTHingeyjarsveit, NortheastIceland146 km (91 mi)SW of epicenterVik(pop: 750)II: Very weakMyrdalshreppur, SouthIceland148 km (92 mi)N of epicenterLaugar(pop: 1000)II: Very weakTHingeyjarsveit, NortheastIceland151 km (94 mi)NE of epicenterReydarfjordur(pop: 1,150)II: Very weakFjardabyggd, EastIceland151 km (94 mi)N of epicenterAkureyri(pop: 19,200)II: Very weakAkureyrarkaupstadur, NortheastIceland155 km (96 mi)NE of epicenterFaskrudsfjoerdur(pop: 654)II: Very weakFjardabyggd, EastIceland158 km (98 mi)NE of epicenterEgilsstadir(pop: 2,570)II: Very weakMulathing, EastIceland158 km (98 mi)E of epicenterStodvarfjordur(pop: 189)II: Very weakFjardabyggd, EastIceland162 km (100 mi)NE of epicenterEskifjordur(pop: 1,010)II: Very weakFjardabyggd, EastIceland162 km (100 mi)W of epicenterFludir(pop: 818)II: Very weakHrunamannahreppur, SouthIceland171 km (106 mi)SW of epicenterHvolsvollur(pop: 1,040)II: Very weakRangarthing Eystra, SouthIceland172 km (107 mi)NE of epicenterSeydisfjoerdur(pop: 676)II: Very weakMulathing, EastIceland175 km (109 mi)W of epicenterHella(pop: 865)II: Very weakRangarthing Ytra, SouthIceland179 km (111 mi)NE of epicenterNeskaupstadur(pop: 1,480)II: Very weakFjardabyggd, EastIceland181 km (112 mi)N of epicenterGrenvik(pop: 278)II: Very weakGrytubakkahreppur, NortheastIceland183 km (114 mi)NE of epicenterVopnafjordur(pop: 543)II: Very weakVopnafjardarhreppur, EastIceland183 km (114 mi)N of epicenterNordurthing(pop: 2,230)II: Very weakNordurthing, NortheastIceland188 km (117 mi)N of epicenterDalvik(pop: 1,360)II: Very weakDalvikurbyggd, NortheastIceland191 km (119 mi)SW of epicenterVestmannaeyjar(pop: 4,220)II: Very weakSouthIceland193 km (120 mi)NW of epicenterSauðarkrokur(pop: 2,610)II: Very weakSveitarfelagid Skagafjoerdur, NorthwestIceland199 km (124 mi)W of epicenterSelfoss(pop: 9,000)II: Very weakSveitarfelagid Arborg, SouthIceland200 km (124 mi)N of epicenterOlafsfjordur(pop: 785)II: Very weakFjallabyggd, NortheastIceland206 km (128 mi)W of epicenterHveragerdi(pop: 2,290)II: Very weakHveragerdisbaer, SouthIceland207 km (129 mi)NW of epicenterBlonduos(pop: 813)II: Very weakHunabyggd, NorthwestIceland209 km (130 mi)W of epicenterEyrarbakki(pop: 531)II: Very weakSveitarfelagid Arborg, SouthIceland214 km (133 mi)NW of epicenterSiglufjordur(pop: 1,190)II: Very weakFjallabyggd, NortheastIceland215 km (134 mi)N of epicenterTourskhjobn(pop: 379)II: Very weakLanganesbyggd, NortheastIceland215 km (134 mi)NW of epicenterHvammstangi(pop: 546)II: Very weakHunathing Vestra, NorthwestIceland220 km (136 mi)W of epicenterThorlakshofn(pop: 2,040)II: Very weakSveitarfelagid OElfus, SouthIceland220 km (137 mi)NW of epicenterSkagastrond(pop: 470)II: Very weakSveitarfelagid Skagastroend, NorthwestIceland227 km (141 mi)W of epicenterMosfellsbaer(pop: 12,100)II: Very weakCapital RegionIceland232 km (144 mi)W of epicenterGrundarhverfi(pop: 528)II: Very weakReykjavikurborg, Capital RegionIceland234 km (145 mi)W of epicenterBorgarnes(pop: 1,880)II: Very weakBorgarbyggd, WestIceland237 km (147 mi)W of epicenterReykjavik(pop: 118,900)II: Very weakReykjavikurborg, Capital RegionIceland238 km (148 mi)W of epicenterKopavogur(pop: 38,000)II: Very weakKopavogsbaer, Capital RegionIceland239 km (148 mi)W of epicenterGarðabaer(pop: 11,400)II: Very weakGardabaer, Capital RegionIceland240 km (149 mi)W of epicenterHafnarfjordur(pop: 30,000)II: Very weakHafnarfjardarkaupstadur, Capital RegionIcelandNotes:(*) Shaking intensity according to the Modified Mercalli Intensity Scale (MMI) and estimated using seismic models.User-reports for this quakeThere are no user reports for this quake yet.If you felt it, be the first to report it!Get the Android appCompare Quake DataData for the same earthquake as reported by different agenciesThe more agencies report about the same quake and post similar data, the more confidence you can have in the data.

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 3 km2 (1 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 3 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Oct 3, 2026 11:53 am (Reykjavik)23 minutes ago4.55.2 km0 km - This quakeIceland: 11.7 km E of GrímsfjallMain 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 5,800 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 5 or higher: 2.2 quakes per yearMag. 4 or higher: 9.5 quakes per yearMag. 3 or higher: 36.3 quakes per year (or 3 quakes per month)Mag. 2 or higher: 204 quakes per year (or 17 quakes per month)Mag. 1 or higher: 1,500 quakes per year (or 4.1 quakes per day)The area where this quake occurred has a high level of seismic activity. It has had at least 59 quakes above magnitude 5 since 2000, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 1 to 5 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
