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, 368 km (229 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(*)RegionCountry57 km (35 mi)W of epicenterLapi(pop: 2,850)III: WeakProvince of Cagayan, Cagayan ValleyPhilippines59 km (36 mi)S of epicenterDicabisagan(pop: 3,500)III: WeakProvince of Isabela, Cagayan ValleyPhilippines66 km (41 mi)NW of epicenterSan Jose(pop: 4,530)III: WeakProvince of Cagayan, Cagayan ValleyPhilippines66 km (41 mi)W of epicenterAggugaddah(pop: 2,360)III: WeakProvince of Cagayan, Cagayan ValleyPhilippines69 km (43 mi)SW of epicenterAntagan Segunda(pop: 4,070)III: WeakProvince of Isabela, Cagayan ValleyPhilippines69 km (43 mi)W of epicenterDivisoria(pop: 2,070)III: WeakProvince of Cagayan, Cagayan ValleyPhilippines72 km (45 mi)W of epicenterCabagan(pop: 25,300)III: WeakProvince of Isabela, Cagayan ValleyPhilippines74 km (46 mi)W of epicenterTuguegarao(pop: 166,300)III: WeakProvince of Cagayan, Cagayan ValleyPhilippines75 km (46 mi)SW of epicenterSindon(pop: 2,420)III: WeakProvince of Isabela, Cagayan ValleyPhilippines76 km (47 mi)SW of epicenterRagan Norte(pop: 4,220)II: Very weakProvince of Isabela, Cagayan ValleyPhilippines76 km (47 mi)SW of epicenterIlagan(pop: 72,400)II: Very weakProvince of Isabela, Cagayan ValleyPhilippines76 km (47 mi)W of epicenterNattapian(pop: 11,900)II: Very weakProvince of Cagayan, Cagayan ValleyPhilippines77 km (48 mi)W of epicenterSolana(pop: 71,500)II: Very weakProvince of Cagayan, Cagayan ValleyPhilippines78 km (48 mi)W of epicenterAmulung(pop: 2,350)II: Very weakProvince of Cagayan, Cagayan ValleyPhilippines80 km (50 mi)NW of epicenterTaguing(pop: 2,080)II: Very weakProvince of Cagayan, Cagayan ValleyPhilippines80 km (50 mi)NW of epicenterCapissayan Sur(pop: 2,880)II: Very weakProvince of Cagayan, Cagayan ValleyPhilippines82 km (51 mi)SW of epicenterSan Mariano(pop: 12,400)II: Very weakProvince of Isabela, Cagayan ValleyPhilippines85 km (53 mi)NW of epicenterGonzaga(pop: 7,230)II: Very weakProvince of Cagayan, Cagayan ValleyPhilippines87 km (54 mi)NW of epicenterCabiraoan(pop: 2,930)II: Very weakProvince of Cagayan, Cagayan ValleyPhilippines89 km (55 mi)NW of epicenterPalagao Norte(pop: 2,950)II: Very weakProvince of Cagayan, Cagayan ValleyPhilippines90 km (56 mi)SW of epicenterNaguilian(pop: 8,560)II: Very weakProvince of Isabela, Cagayan ValleyPhilippines95 km (59 mi)NW of epicenterPattao(pop: 3,220)II: Very weakProvince of Cagayan, Cagayan ValleyPhilippines96 km (59 mi)SW of epicenterBurgos(pop: 6,580)II: Very weakProvince of Isabela, Cagayan ValleyPhilippines99 km (61 mi)NW of epicenterMagapit(pop: 11,200)II: Very weakProvince of Cagayan, Cagayan ValleyPhilippines105 km (65 mi)SW of epicenterMinante Segundo(pop: 6,700)II: Very weakProvince of Isabela, Cagayan ValleyPhilippines107 km (67 mi)NW of epicenterPaddaya(pop: 4,440)II: Very weakProvince of Cagayan, Cagayan ValleyPhilippines111 km (69 mi)SW of epicenterLa Paz(pop: 4,020)II: Very weakProvince of Isabela, Cagayan ValleyPhilippines368 km (229 mi)SW of epicenterManila(pop: 1,600,000)I: Not feltCapital, 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 2 km2 (1 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)11 October 2025 - 12:54 AM (PST)12 minutes ago4.219 km0 km - This quakePhilippines: 032 km N 38° E of Maconacon (Isabela)Main Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 55 years and our earthquake archive back to 1900, there are about 134 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: 0.04 quakes per year (or 1 quake every 25 years)Mag. 5 or higher: 0.9 quakes per year (or 1 quake every 1.1 years)Mag. 4 or higher: 15.9 quakes per yearMag. 3 or higher: 39.6 quakes per year (or 3.3 quakes per month)Mag. 2 or higher: 127 quakes per year (or 10.6 quakes per month)Mag. 1 or higher: 144 quakes per year (or 12 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
