People likely experienced very weak shaking there. Many smaller towns and villages are located closer to the epicenter and might have experienced stronger shaking. In the capital of  New Zealand, Wellington, 318 km (198 mi) away from the epicenter, the earthquake could not be felt.The following table shows some of the places that might have been affected (or not) by the shaking.DistancePlaceMax. shaking intensity(*)RegionCountry8 km (5 mi)S of epicenterArthur's Pass(pop: 930)IV: LightSelwyn District, CanterburyNew Zealand32 km (20 mi)N of epicenterGloriavale Christian Church(pop: 570)III: WeakGrey District, West CoastNew Zealand42 km (26 mi)NW of epicenterKumara(pop: 285)III: WeakWestland District, West CoastNew Zealand51 km (31 mi)N of epicenterDobson(pop: 828)III: WeakGrey District, West CoastNew Zealand52 km (32 mi)W of epicenterHokitika(pop: 3,350)III: WeakWestland District, West CoastNew Zealand55 km (34 mi)NW of epicenterGreymouth(pop: 9,420)III: WeakGrey District, West CoastNew Zealand58 km (36 mi)N of epicenterBlackball(pop: 321)III: WeakGrey District, West CoastNew Zealand58 km (36 mi)SE of epicenterSpringfield(pop: 318)III: WeakSelwyn District, CanterburyNew Zealand59 km (36 mi)N of epicenterAhaura(pop: 669)III: WeakGrey District, West CoastNew Zealand69 km (43 mi)SE of epicenterOxford(pop: 2,240)II: Very weakWaimakariri District, CanterburyNew Zealand72 km (45 mi)N of epicenterBarrytown(pop: 225)II: Very weakGrey District, West CoastNew Zealand75 km (47 mi)SE of epicenterCoalgate(pop: 339)II: Very weakSelwyn District, CanterburyNew Zealand81 km (50 mi)SE of epicenterDarfield(pop: 3,380)II: Very weakSelwyn District, CanterburyNew Zealand84 km (52 mi)S of epicenterMethven(pop: 2,130)II: Very weakAshburton District, CanterburyNew Zealand85 km (53 mi)SE of epicenterWest Eyreton(pop: 1,620)II: Very weakWaimakariri District, CanterburyNew Zealand88 km (55 mi)N of epicenterReefton(pop: 927)II: Very weakBuller District, West CoastNew Zealand95 km (59 mi)SE of epicenterRangiora(pop: 19,200)II: Very weakWaimakariri District, CanterburyNew Zealand100 km (62 mi)E of epicenterAmberley(pop: 2,780)II: Very weakHurunui District, CanterburyNew Zealand103 km (64 mi)SE of epicenterRolleston(pop: 33,200)II: Very weakSelwyn District, CanterburyNew Zealand103 km (64 mi)SE of epicenterKaiapoi(pop: 13,600)II: Very weakWaimakariri District, CanterburyNew Zealand104 km (64 mi)SE of epicenterWaikuku Beach(pop: 1,130)II: Very weakWaimakariri District, CanterburyNew Zealand104 km (65 mi)S of epicenterRakaia(pop: 1,670)II: Very weakAshburton District, CanterburyNew Zealand109 km (68 mi)SE of epicenterWigram(pop: 11,900)II: Very weakChristchurch City, CanterburyNew Zealand110 km (68 mi)E of epicenterHanmer Springs(pop: 1,180)II: Very weakHurunui District, CanterburyNew Zealand113 km (70 mi)SE of epicenterHalswell(pop: 13,200)II: Very weakChristchurch City, CanterburyNew Zealand113 km (70 mi)SE of epicenterChristchurch(pop: 412,000)II: Very weakCanterburyNew Zealand114 km (71 mi)SE of epicenterLincoln(pop: 9,180)II: Very weakSelwyn District, CanterburyNew Zealand114 km (71 mi)SE of epicenterSpreydon(pop: 10,200)II: Very weakChristchurch City, CanterburyNew Zealand114 km (71 mi)S of epicenterAshburton(pop: 21,300)II: Very weakCanterburyNew Zealand115 km (72 mi)SE of epicenterLeeston(pop: 2,490)II: Very weakSelwyn District, CanterburyNew Zealand124 km (77 mi)SE of epicenterSumner(pop: 3,520)II: Very weakChristchurch City, CanterburyNew Zealand125 km (78 mi)N of epicenterWestport(pop: 4,600)II: Very weakBuller District, West CoastNew Zealand131 km (81 mi)S of epicenterEaling(pop: 1,740)II: Very weakAshburton District, CanterburyNew Zealand138 km (86 mi)S of epicenterGeraldine(pop: 2,300)II: Very weakTimaru District, CanterburyNew Zealand151 km (94 mi)SW of epicenterWaikowhai(pop: 5,550)II: Very weakWestland District, West CoastNew Zealand152 km (95 mi)S of epicenterTemuka(pop: 4,840)II: Very weakTimaru District, CanterburyNew Zealand159 km (99 mi)S of epicenterPleasant Point(pop: 1,470)II: Very weakTimaru District, CanterburyNew Zealand194 km (120 mi)SW of epicenterTwizel(pop: 1,780)I: Not feltMackenzie District, CanterburyNew Zealand218 km (135 mi)NE of epicenterWairau Valley(pop: 2,230)I: Not feltMarlborough District, MarlboroughNew Zealand318 km (198 mi)NE of epicenterWellington(pop: 381,900)I: Not feltWellingtonNew ZealandNotes:(*) 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 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)Jun 24, 2026 06:31 am (Universal Time)3 minutes ago4.010 km0 km - This quakeNew ZealandMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 56 years and our earthquake archive back to 1900, there are about 581 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: 0.06 quakes per year (or 1 quake every 15.9 years)Mag. 5 or higher: 0.64 quakes per year (or 1 quake every 1.6 years)Mag. 4 or higher: 9.5 quakes per yearMag. 3 or higher: 46 quakes per year (or 3.8 quakes per month)Mag. 2 or higher: 321 quakes per year (or 26.7 quakes per month)Mag. 1 or higher: 582 quakes per year (or 48 quakes per month)The area where this quake occurred has a 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 earthquake
