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 El Salvador, San Salvador, 163 km (101 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(*)RegionCountry29 km (18 mi)N of epicenterConchagua(pop: 3,030)II: Very weakDepartamento de La UnionEl Salvador32 km (20 mi)N of epicenterLa Union(pop: 26,800)II: Very weakDepartamento de La UnionEl Salvador33 km (20 mi)NE of epicenterAmapala(pop: 2,140)II: Very weakDepartamento de ValleHonduras39 km (24 mi)NW of epicenterChirilagua(pop: 6,390)II: Very weakDepartamento de San MiguelEl Salvador45 km (28 mi)N of epicenterSan Alejo(pop: 5,150)II: Very weakDepartamento de La UnionEl Salvador51 km (32 mi)NW of epicenterJucuaran(pop: 1,640)II: Very weakDepartamento de UsulutanEl Salvador52 km (32 mi)E of epicenterMonjaras(pop: 6,770)II: Very weakMarcovia, Departamento de CholutecaHonduras52 km (33 mi)N of epicenterLa Alianza(pop: 6,920)II: Very weakAlianza, Departamento de ValleHonduras53 km (33 mi)SE of epicenterJiquilillo(pop: 4,140)II: Very weakDepartamento de ChinandegaNicaragua55 km (34 mi)NE of epicenterAgua Fria(pop: 3,200)II: Very weakNacaome, Departamento de ValleHonduras56 km (35 mi)NE of epicenterSan Jose de Las Conchas(pop: 1,080)II: Very weakMarcovia, Departamento de CholutecaHonduras58 km (36 mi)NE of epicenterSan Lorenzo(pop: 22,300)II: Very weakDepartamento de ValleHonduras62 km (38 mi)NW of epicenterSan Miguel(pop: 247,100)II: Very weakDepartamento de San MiguelEl Salvador62 km (39 mi)NE of epicenterMarcovia(pop: 1,930)II: Very weakDepartamento de CholutecaHonduras64 km (40 mi)N of epicenterSanta Rosa de Lima(pop: 13,200)II: Very weakDepartamento de La UnionEl Salvador66 km (41 mi)N of epicenterLangue(pop: 3,680)II: Very weakDepartamento de ValleHonduras66 km (41 mi)N of epicenterJocoro(pop: 4,300)II: Very weakDepartamento de MorazanEl Salvador68 km (42 mi)NW of epicenterSan Rafael Oriente(pop: 19,100)II: Very weakDepartamento de San MiguelEl Salvador68 km (42 mi)NE of epicenterJicaro Galan(pop: 1,370)II: Very weakNacaome, Departamento de ValleHonduras75 km (46 mi)E of epicenterPuerto Morazan(pop: 7,670)II: Very weakMunicipio de Puerto Morazan, Departamento de ChinandegaNicaragua75 km (47 mi)NE of epicenterSan Francisco de Coray(pop: 1,330)II: Very weakDepartamento de ValleHonduras76 km (47 mi)E of epicenterSan Jeronimo(pop: 2,380)II: Very weakNamasigue, Departamento de CholutecaHonduras77 km (48 mi)N of epicenterAnamoros(pop: 2,660)II: Very weakDepartamento de La UnionEl Salvador78 km (48 mi)N of epicenterAramecina(pop: 1,070)II: Very weakDepartamento de ValleHonduras78 km (49 mi)NE of epicenterPespire(pop: 3,170)II: Very weakDepartamento de CholutecaHonduras79 km (49 mi)NW of epicenterJucuapa(pop: 10,600)II: Very weakDepartamento de UsulutanEl Salvador79 km (49 mi)NW of epicenterGuatajiagua(pop: 5,270)II: Very weakDepartamento de MorazanEl Salvador82 km (51 mi)NW of epicenterOzatlan(pop: 4,170)II: Very weakDepartamento de UsulutanEl Salvador82 km (51 mi)E of epicenterSanta Ana de Yusguare(pop: 1,820)II: Very weakDepartamento de CholutecaHonduras82 km (51 mi)W of epicenterPuerto El Triunfo(pop: 19,100)II: Very weakDepartamento de UsulutanEl Salvador84 km (52 mi)SE of epicenterEl Viejo(pop: 53,500)II: Very weakDepartamento de ChinandegaNicaragua84 km (52 mi)NW of epicenterSantiago de Maria(pop: 15,000)II: Very weakDepartamento de UsulutanEl Salvador84 km (52 mi)N of epicenterCacaopera(pop: 2,530)II: Very weakDepartamento de MorazanEl Salvador89 km (55 mi)SE of epicenterChinandega(pop: 126,400)II: Very weakDepartamento de ChinandegaNicaragua91 km (57 mi)NW of epicenterBerlin(pop: 11,300)II: Very weakDepartamento de UsulutanEl Salvador93 km (58 mi)NW of epicenterCiudad Barrios(pop: 8,490)II: Very weakDepartamento de San MiguelEl Salvador94 km (59 mi)NW of epicenterSesori(pop: 1,390)II: Very weakDepartamento de San MiguelEl Salvador95 km (59 mi)NE of epicenterEl Porvenir(pop: 3,150)II: Very weakLa Venta, Departamento de Francisco MorazanHonduras95 km (59 mi)SE of epicenterCorinto(pop: 19,200)II: Very weakDepartamento de ChinandegaNicaragua163 km (101 mi)NW of epicenterSan Salvador(pop: 526,000)II: Very weakDepartamento de San SalvadorEl SalvadorNotes:(*) 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 3 km2 (1 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 3 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Oct 10, 2025 06:27 am (Universal Time)4 minutes ago4.5170 km0 km - This quakeOffshore EL SalvadorMain 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 1,000 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 years)Mag. 6 or higher: 0.21 quakes per year (or 1 quake every 4.8 years)Mag. 5 or higher: 3.7 quakes per yearMag. 4 or higher: 55 quakes per year (or 4.5 quakes per month)Mag. 3 or higher: 349 quakes per year (or 29 quakes per month)Mag. 2 or higher: 923 quakes per year (or 77 quakes per month)Mag. 1 or higher: 1,000 quakes per year (or 2.7 quakes per day)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 23 to 27 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
