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 Costa Rica, San Jose, 163 km (102 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(*)RegionCountry21 km (13 mi)SE of epicenterGolfito(pop: 6,780)III: WeakProvincia de PuntarenasCosta Rica36 km (22 mi)NE of epicenterSan Vito(pop: 3,980)III: WeakCoto Brus, Provincia de PuntarenasCosta Rica36 km (23 mi)E of epicenterCorredor(pop: 7,080)III: WeakProvincia de PuntarenasCosta Rica40 km (25 mi)NW of epicenterPuerto Cortes(pop: 3,850)III: WeakOsa, Provincia de PuntarenasCosta Rica42 km (26 mi)E of epicenterAlto Quiel(pop: 576)III: WeakDistrito de Renacimiento, Provincia de ChiriquiPanama47 km (29 mi)E of epicenterRio Sereno(pop: 1,370)III: WeakDistrito de Renacimiento, Provincia de ChiriquiPanama51 km (32 mi)E of epicenterCanoas(pop: 4,570)III: WeakCorredores, Provincia de PuntarenasCosta Rica52 km (32 mi)E of epicenterDominical(pop: 439)III: WeakDistrito de Renacimiento, Provincia de ChiriquiPanama53 km (33 mi)N of epicenterBuenos Aires(pop: 11,700)III: WeakProvincia de PuntarenasCosta Rica56 km (35 mi)SE of epicenterFinca Blanco(pop: 1,060)III: WeakDistrito de Baru, Provincia de ChiriquiPanama57 km (35 mi)SE of epicenterCabecera de San Bartolo(pop: 58)III: WeakDistrito de Baru, Provincia de ChiriquiPanama58 km (36 mi)E of epicenterPiedra Candela(pop: 648)III: WeakDistrito de Renacimiento, Provincia de ChiriquiPanama60 km (38 mi)E of epicenterGomez(pop: 1,260)II: Very weakDistrito de Bugaba, Provincia de ChiriquiPanama62 km (39 mi)E of epicenterQuebrada Llana(pop: 125)II: Very weakDistrito de Bugaba, Provincia de ChiriquiPanama65 km (40 mi)SE of epicenterPuerto Armuelles(pop: 11,700)II: Very weakDistrito de Baru, Provincia de ChiriquiPanama69 km (43 mi)SE of epicenterDivala(pop: 2,510)II: Very weakDistrito de Alanje, Provincia de ChiriquiPanama69 km (43 mi)SE of epicenterMajagual(pop: 521)II: Very weakDistrito de Baru, Provincia de ChiriquiPanama70 km (44 mi)E of epicenterVolcan(pop: 10,300)II: Very weakTierras Altas, Provincia de ChiriquiPanama72 km (45 mi)NW of epicenterMercedes(pop: 5,470)II: Very weakPerez Zeledon, Provincia de San JoseCosta Rica74 km (46 mi)E of epicenterLa Concepcion(pop: 17,700)II: Very weakDistrito de Bugaba, Provincia de ChiriquiPanama78 km (48 mi)E of epicenterSanta Rita(pop: 465)II: Very weakDistrito de Boqueron, Provincia de ChiriquiPanama79 km (49 mi)E of epicenterCerro Punta(pop: 1,570)II: Very weakTierras Altas, Provincia de ChiriquiPanama83 km (52 mi)NW of epicenterDaniel Flores(pop: 10,000)II: Very weakPerez Zeledon, Provincia de San JoseCosta Rica85 km (53 mi)E of epicenterAlanje(pop: 1,370)II: Very weakProvincia de ChiriquiPanama86 km (54 mi)SE of epicenterBurica(pop: 1,360)II: Very weakDistrito de Baru, Provincia de ChiriquiPanama88 km (54 mi)NW of epicenterSan Isidro(pop: 34,900)II: Very weakPerez Zeledon, Provincia de San JoseCosta Rica88 km (55 mi)SE of epicenterLa Barqueta(pop: 36)II: Very weakProvincia de ChiriquiPanama104 km (65 mi)NE of epicenterCochigro(pop: 201)II: Very weakDistrito de Changuinola, Provincia de Bocas del ToroPanama163 km (102 mi)NW of epicenterSan Jose(pop: 335,000)II: Very weakSan Jose, Provincia de San JoseCosta RicaNotes:(*) 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 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)2025-08-25 02:20:078 minutes ago4.05 km0 km - This quake39 km Al Noreste De Playa Madrigal, Costa RicaMain 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 862 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: 0.23 quakes per year (or 1 quake every 4.3 years)Mag. 5 or higher: 2.7 quakes per yearMag. 4 or higher: 60 quakes per year (or 5 quakes per month)Mag. 3 or higher: 505 quakes per year (or 42 quakes per month)Mag. 2 or higher: 843 quakes per year (or 70 quakes per month)Mag. 1 or higher: 860 quakes per year (or 72 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 earthquake
