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 Timor-Leste, Dili, 138 km (86 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(*)RegionCountry25 km (16 mi)W of epicenterKefamenanu(pop: 48,200)III: WeakKabupaten Timor Tengah Utara, East Nusa TenggaraIndonesia44 km (27 mi)NE of epicenterAtambua(pop: 82,200)III: WeakKabupaten Belu, East Nusa TenggaraIndonesia46 km (29 mi)E of epicenterTilomar(pop: 7,890)III: WeakKovalimaEast Timor52 km (32 mi)NW of epicenterLifau(pop: 1,940)III: WeakPante Makasar, OecusseEast Timor65 km (40 mi)SW of epicenterSoe(pop: 40,200)III: WeakKabupaten Timor Tengah Selatan, East Nusa TenggaraIndonesia102 km (63 mi)NE of epicenterAinaro(pop: 12,000)II: Very weakAinaroEast Timor104 km (65 mi)W of epicenterNaisano Dua(pop: 2,350)II: Very weakKabupaten Kupang, East Nusa TenggaraIndonesia109 km (68 mi)NE of epicenterMaubara(pop: 16,300)II: Very weakLiquicaEast Timor114 km (71 mi)NE of epicenterGleno(pop: 8,130)II: Very weakErmera Villa, ErmeraEast Timor115 km (71 mi)NE of epicenterSame(pop: 7,500)II: Very weakManufahiEast Timor119 km (74 mi)NE of epicenterLikisa(pop: 19,000)II: Very weakBazartete, LiquicaEast Timor124 km (77 mi)NE of epicenterAileu(pop: 17,400)II: Very weakAileuEast Timor138 km (86 mi)NE of epicenterDili(pop: 150,000)II: Very weakDistrito de Aveiro, DiliEast Timor140 km (87 mi)N of epicenterKalabahi(pop: 19,200)II: Very weakKabupaten Alor, East Nusa TenggaraIndonesia144 km (90 mi)SW of epicenterKupang(pop: 442,800)II: Very weakEast Nusa TenggaraIndonesia153 km (95 mi)NE of epicenterMetinaro(pop: 4,000)II: Very weakDiliEast Timor165 km (102 mi)NE of epicenterBarique(pop: 5,440)II: Very weakManatutoEast Timor165 km (102 mi)NE of epicenterAtauro(pop: 9,270)II: Very weakDiliEast Timor178 km (111 mi)NE of epicenterManatutu(pop: 1,920)II: Very weakManatuto, ManatutoEast Timor187 km (116 mi)NW of epicenterLewoleba(pop: 30,200)II: Very weakKabupaten Lembata, East Nusa TenggaraIndonesia194 km (120 mi)E of epicenterViqueque(pop: 6,080)II: Very weakViquequeEast Timor205 km (127 mi)NE of epicenterVenilale(pop: 16,000)I: Not feltBaucauEast Timor221 km (137 mi)NE of epicenterBaukau(pop: 16,000)I: Not feltBaucau, BaucauEast Timor230 km (143 mi)SW of epicenterBaa(pop: 1,260)I: Not feltKabupaten Rote Ndao, East Nusa TenggaraIndonesia232 km (144 mi)E of epicenterIrabin de Baixo(pop: 2,450)I: Not feltUatocarabau, ViquequeEast Timor255 km (158 mi)NE of epicenterLuro(pop: 2,840)I: Not feltLauteinEast Timor270 km (168 mi)NE of epicenterLautem(pop: 3,160)I: Not feltLauteinEast Timor272 km (169 mi)E of epicenterLospalos(pop: 17,200)I: Not feltLauteinEast Timor290 km (180 mi)W of epicenterMaumere(pop: 87,700)I: Not feltKabupaten Sikka, East Nusa TenggaraIndonesia304 km (189 mi)NE of epicenterTutuala(pop: 3,710)I: Not feltLauteinEast TimorNotes:(*) 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)Aug 31, 2026 11:58 am (GMT +8)10 minutes ago4.110 km0 km - This quake25 km E of Kefamenanu, IndonesiaMain 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 193 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.07 quakes per year (or 1 quake every 14.1 years)Mag. 5 or higher: 1.23 quakes per yearMag. 4 or higher: 18.5 quakes per yearMag. 3 or higher: 80 quakes per year (or 6.7 quakes per month)Mag. 2 or higher: 191 quakes per year (or 15.9 quakes per month)Mag. 1 or higher: 193 quakes per year (or 16.1 quakes per month)The area where this quake occurred has a high level of seismic activity. It has had at least 9 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 10 to 15 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
