Moderate magnitude 4.7 earthquake at 163 km depth20 Sep 00:11 UTC: First to report: RaspberryShake after 17 minutes.20 Sep 00:11: Now using data updates from BMKGUpdate Sun, 20 Sep 2026, 00:12Moderate magnitude 4.7 earthquake 48 km northwest of Tiakur, IndonesiaAn earthquake of magnitude 4.7 occurred in the morning on Sunday, September 20th, 2026, at 8:54 am local time near Tiakur, Southwest Maluku Regency, Maluku, Indonesia, as reported by Indonesia's Meteorology, Climatology, and Geophysical Agency.According to preliminary data, the quake was located at an intermediate to considerable depth of 163. km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 4.7 earthquake as well.Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Tiakur (pop. 5,200) located 48 km from the epicenter, Tutuala (pop. 3,700) 68 km away, Lautem (pop. 3,200) 89 km away, and Lospalos (pop. 17,200) 95 km away.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.

People likely experienced very 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, 227 km (141 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(*)RegionCountry48 km (30 mi)SE of epicenterTiakur(pop: 5,230)II: Very weakKabupaten Maluku Barat Daya, MalukuIndonesia68 km (42 mi)SW of epicenterTutuala(pop: 3,710)II: Very weakLauteinEast Timor89 km (55 mi)SW of epicenterLautem(pop: 3,160)II: Very weakLauteinEast Timor95 km (59 mi)SW of epicenterLospalos(pop: 17,200)II: Very weakLauteinEast Timor108 km (67 mi)SW of epicenterLuro(pop: 2,840)II: Very weakLauteinEast Timor135 km (84 mi)SW of epicenterIrabin de Baixo(pop: 2,450)II: Very weakUatocarabau, ViquequeEast Timor136 km (84 mi)SW of epicenterBaukau(pop: 16,000)II: Very weakBaucau, BaucauEast Timor153 km (95 mi)SW of epicenterVenilale(pop: 16,000)II: Very weakBaucauEast Timor169 km (105 mi)SW of epicenterViqueque(pop: 6,080)II: Very weakViquequeEast Timor193 km (120 mi)SW of epicenterBarique(pop: 5,440)II: Very weakManatutoEast Timor209 km (130 mi)W of epicenterMetinaro(pop: 4,000)II: Very weakDiliEast Timor215 km (133 mi)W of epicenterAtauro(pop: 9,270)II: Very weakDiliEast Timor227 km (141 mi)W of epicenterDili(pop: 150,000)II: Very weakDistrito de Aveiro, DiliEast Timor235 km (146 mi)SW of epicenterAileu(pop: 17,400)II: Very weakAileuEast Timor242 km (150 mi)SW of epicenterSame(pop: 7,500)II: Very weakManufahiEast Timor248 km (154 mi)SW of epicenterGleno(pop: 8,130)II: Very weakErmera Villa, ErmeraEast Timor252 km (157 mi)W of epicenterLikisa(pop: 19,000)II: Very weakBazartete, LiquicaEast Timor254 km (158 mi)SW of epicenterAinaro(pop: 12,000)II: Very weakAinaroEast Timor267 km (166 mi)W of epicenterMaubara(pop: 16,300)II: Very weakLiquicaEast Timor282 km (175 mi)SW of epicenterMaliana(pop: 22,000)II: Very weakBobonaroEast Timor297 km (184 mi)SW of epicenterSuai(pop: 21,500)II: Very weakKovalimaEast Timor320 km (199 mi)SW of epicenterAtambua(pop: 82,200)II: Very weakKabupaten Belu, East Nusa TenggaraIndonesia328 km (204 mi)W of epicenterKalabahi(pop: 19,200)II: Very weakKabupaten Alor, East Nusa TenggaraIndonesia378 km (235 mi)SW of epicenterKefamenanu(pop: 48,200)I: Not feltKabupaten Timor Tengah Utara, East Nusa TenggaraIndonesia419 km (260 mi)E of epicenterSaumlaki(pop: 13,800)I: Not feltKabupaten Maluku Tenggara Barat, MalukuIndonesia419 km (261 mi)SW of epicenterSoe(pop: 40,200)I: Not feltKabupaten Timor Tengah Selatan, East Nusa TenggaraIndonesia451 km (281 mi)N of epicenterNamrole(pop: 21,500)I: Not feltKabupaten Buru Selatan, MalukuIndonesia454 km (282 mi)W of epicenterLewoleba(pop: 30,200)I: Not feltKabupaten Lembata, East Nusa TenggaraIndonesia466 km (290 mi)N of epicenterAmbon(pop: 347,300)I: Not feltMalukuIndonesia501 km (311 mi)SW of epicenterKupang(pop: 442,800)I: Not feltEast Nusa TenggaraIndonesia510 km (317 mi)N of epicenterNamlea(pop: 37,900)I: Not feltKabupaten Buru, MalukuIndonesia524 km (325 mi)N of epicenterAmahai(pop: 47,700)I: Not feltKabupaten Maluku Tengah, MalukuIndonesia530 km (329 mi)N of epicenterMasohi(pop: 36,400)I: Not feltKabupaten Maluku Tengah, MalukuIndonesia589 km (366 mi)W of epicenterMaumere(pop: 87,700)I: Not feltKabupaten Sikka, East Nusa TenggaraIndonesia602 km (374 mi)NW of epicenterBaubau(pop: 161,300)I: Not feltSoutheast SulawesiIndonesia624 km (388 mi)NW of epicenterRaha(pop: 70,000)I: Not feltKabupaten Muna, Southeast SulawesiIndonesia624 km (388 mi)NW of epicenterKatobu(pop: 31,900)I: Not feltKabupaten Muna, Southeast SulawesiIndonesia630 km (391 mi)NE of epicenterTual(pop: 90,000)I: Not feltMalukuIndonesia632 km (393 mi)SE of epicenterDarwin(pop: 139,900)I: Not feltNorthern TerritoryAustralia698 km (434 mi)NW of epicenterKendari(pop: 345,100)I: Not feltSoutheast SulawesiIndonesiaNotes:(*) 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 5 km2 (2 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 4 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Sep 20, 2026 08:54 am (GMT +9)20 minutes ago4.7163 km0 km - This quakeBanda Sea, 29 km S of Pulau Maopora Island, Maluku, 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 72 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.04 quakes per year (or 1 quake every 25.6 years)Mag. 6 or higher: 0.22 quakes per year (or 1 quake every 4.6 years)Mag. 5 or higher: 2.5 quakes per yearMag. 4 or higher: 58 quakes per year (or 4.9 quakes per month)Mag. 3 or higher: 72 quakes per year (or 6 quakes per month)Mag. 2 or higher: 74 quakes per year (or 6.2 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 5 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 25 to 30 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
