People likely experienced weak shaking there. Many smaller towns and villages are located closer to the epicenter and might have experienced stronger shaking. In the capital of the Philippines, Manila, 422 km (262 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(*)RegionCountry12 km (8 mi)NE of epicenterCapul(pop: 4,760)V: ModerateProvince of Northern Samar, Eastern VisayasPhilippines24 km (15 mi)E of epicenterAlegria(pop: 5,810)IV: LightProvince of Northern Samar, Eastern VisayasPhilippines26 km (16 mi)NE of epicenterAllen(pop: 7,500)IV: LightProvince of Northern Samar, Eastern VisayasPhilippines28 km (17 mi)N of epicenterMatnog(pop: 6,720)IV: LightProvince of Sorsogon, BicolPhilippines38 km (23 mi)W of epicenterUson(pop: 4,400)IV: LightProvince of Masbate, BicolPhilippines40 km (25 mi)S of epicenterCataingan(pop: 7,810)IV: LightProvince of Masbate, BicolPhilippines40 km (25 mi)SE of epicenterSan Joaquin(pop: 4,500)IV: LightProvince of Samar, Eastern VisayasPhilippines41 km (25 mi)N of epicenterIrosin(pop: 20,700)IV: LightProvince of Sorsogon, BicolPhilippines41 km (25 mi)W of epicenterSan Fernando(pop: 6,210)IV: LightProvince of Masbate, BicolPhilippines45 km (28 mi)NW of epicenterBulan(pop: 28,500)IV: LightProvince of Sorsogon, BicolPhilippines46 km (28 mi)N of epicenterBulusan(pop: 6,650)IV: LightProvince of Sorsogon, BicolPhilippines51 km (32 mi)SE of epicenterTinambacan(pop: 4,560)IV: LightProvince of Samar, Eastern VisayasPhilippines51 km (32 mi)S of epicenterLimbuhan(pop: 3,190)IV: LightProvince of Masbate, BicolPhilippines53 km (33 mi)W of epicenterMasbate(pop: 47,500)IV: LightBicolPhilippines56 km (35 mi)S of epicenterPlacer(pop: 5,970)IV: LightProvince of Masbate, BicolPhilippines59 km (37 mi)NW of epicenterMonreal(pop: 4,760)IV: LightProvince of Masbate, BicolPhilippines60 km (37 mi)E of epicenterCatarman(pop: 47,400)IV: LightProvince of Northern Samar, Eastern VisayasPhilippines60 km (38 mi)N of epicenterCasiguran(pop: 8,610)IV: LightProvince of Sorsogon, BicolPhilippines61 km (38 mi)SE of epicenterCalbayog City(pop: 67,900)IV: LightProvince of Samar, Eastern VisayasPhilippines65 km (40 mi)N of epicenterGubat(pop: 14,000)IV: LightProvince of Sorsogon, BicolPhilippines67 km (41 mi)W of epicenterMilagros(pop: 6,010)IV: LightProvince of Masbate, BicolPhilippines67 km (42 mi)S of epicenterEsperanza(pop: 17,500)IV: LightProvince of Masbate, BicolPhilippines72 km (45 mi)N of epicenterSorsogon(pop: 82,700)III: WeakBicolPhilippines72 km (45 mi)E of epicenterMondragon(pop: 5,200)III: WeakProvince of Northern Samar, Eastern VisayasPhilippines78 km (49 mi)SE of epicenterPagsanghan(pop: 8,020)III: WeakProvince of Samar, Eastern VisayasPhilippines80 km (50 mi)NW of epicenterPilar(pop: 8,590)III: WeakProvince of Sorsogon, BicolPhilippines89 km (55 mi)SE of epicenterCulaba(pop: 6,230)III: Weak92 km (57 mi)S of epicenterNaval(pop: 12,200)III: WeakBiliran, Eastern VisayasPhilippines92 km (57 mi)E of epicenterPambujan(pop: 10,800)III: WeakProvince of Northern Samar, Eastern VisayasPhilippines98 km (61 mi)NW of epicenterLegaspi(pop: 179,500)III: WeakProvince of Albay, BicolPhilippines100 km (62 mi)SE of epicenterCaibiran(pop: 6,460)III: WeakBiliran, Eastern VisayasPhilippines101 km (63 mi)E of epicenterLaoang(pop: 16,700)III: WeakProvince of Northern Samar, Eastern VisayasPhilippines105 km (65 mi)SE of epicenterCatbalogan(pop: 68,100)III: WeakProvince of Samar, Eastern VisayasPhilippines120 km (75 mi)N of epicenterTabaco(pop: 57,900)III: WeakProvince of Albay, BicolPhilippines122 km (76 mi)NW of epicenterOas(pop: 66,100)III: WeakProvince of Albay, BicolPhilippines126 km (78 mi)NW of epicenterPolangui(pop: 77,100)III: WeakProvince of Albay, BicolPhilippines129 km (80 mi)NW of epicenterLibon(pop: 68,800)III: WeakProvince of Albay, BicolPhilippines143 km (89 mi)NW of epicenterIriga City(pop: 114,500)III: WeakProvince of Camarines Sur, BicolPhilippines156 km (97 mi)SE of epicenterTacloban(pop: 242,100)III: WeakProvince of Leyte, Eastern VisayasPhilippines422 km (262 mi)NW of epicenterManila(pop: 1,600,000)II: Very weakCapital, National Capital RegionPhilippinesNotes:(*) 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!Compare 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 10 km2 (4 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 5 km (3 mi).[More info]Recorded aftershocks, latest first (0 quake)02 October 2025 - 06:21 PM (PST)10 minutes ago5.010 km0 km - This quakePhilippines: 007 km N 9° E of San Vicente (Northern Samar)Main Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 25 years and our earthquake archive back to 1900, there are about 399 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 41.7 years)Mag. 6 or higher: 0.18 quakes per year (or 1 quake every 5.4 years)Mag. 5 or higher: 1.39 quakes per yearMag. 4 or higher: 19.4 quakes per yearMag. 3 or higher: 98 quakes per year (or 8.1 quakes per month)Mag. 2 or higher: 331 quakes per year (or 27.5 quakes per month)Mag. 1 or higher: 399 quakes per year (or 33.3 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 3 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 40 to 45 years.Number of quakes per yearPrevious quakes in the same area of this earthquakeLat / Lng: 12.34 / 124.11: Philippines: 007 km N 9° E of San Vicente (Northern Samar)Lat / Lng: 12.34 / 124.11: Philippines: 007 km N 9° E of San Vicente (Northern Samar)
