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 Chile, Santiago, 240 km (149 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(*)RegionCountry27 km (17 mi)N of epicenterCalingasta(pop: 8,180)II: Very weakSan Juan ProvinceArgentina62 km (39 mi)E of epicenterVilla Basilio Nievas(pop: 4,040)II: Very weakDepartamento de Zonda, San Juan ProvinceArgentina77 km (48 mi)E of epicenterPocito(pop: 41,000)II: Very weakSan Juan ProvinceArgentina81 km (51 mi)E of epicenterVilla Paula de Sarmiento(pop: 19,100)II: Very weakDepartamento de Chimbas, San Juan ProvinceArgentina82 km (51 mi)E of epicenterChimbas(pop: 73,800)II: Very weakSan Juan ProvinceArgentina82 km (51 mi)E of epicenterSan Juan(pop: 109,100)II: Very weakDepartamento de Capital, San Juan ProvinceArgentina83 km (52 mi)E of epicenterAlbardon(pop: 20,400)II: Very weakDepartamento de Albardon, San Juan ProvinceArgentina84 km (52 mi)E of epicenterVilla General San Martin(pop: 10,100)II: Very weakDepartamento de San Martin, San Juan ProvinceArgentina85 km (53 mi)E of epicenterSanta Lucia(pop: 43,600)II: Very weakDepartamento de Santa Lucia, San Juan ProvinceArgentina95 km (59 mi)E of epicenterNueve de Julio(pop: 7,650)II: Very weakSan Juan ProvinceArgentina105 km (65 mi)E of epicenterCaucete(pop: 33,600)II: Very weakSan Juan ProvinceArgentina155 km (96 mi)S of epicenterMendoza(pop: 114,900)II: Very weakDepartamento de Guaymallen, Mendoza ProvinceArgentina161 km (100 mi)N of epicenterSan Jose de Jachal(pop: 21,000)II: Very weakDepartamento de Jachal, San Juan ProvinceArgentina169 km (105 mi)W of epicenterIllapel(pop: 22,800)II: Very weakProvincia de Choapa, Region de CoquimboChile180 km (112 mi)SW of epicenterLos Andes(pop: 63,000)II: Very weakRegion de ValparaisoChile181 km (113 mi)SW of epicenterSan Felipe(pop: 59,300)II: Very weakRegion de ValparaisoChile188 km (117 mi)SE of epicenterSan Martin(pop: 82,500)II: Very weakDepartamento de San Martin, Mendoza ProvinceArgentina204 km (126 mi)NW of epicenterOvalle(pop: 77,100)II: Very weakProvincia de Limari, Region de CoquimboChile217 km (135 mi)SW of epicenterLa Calera(pop: 50,200)II: Very weakQuillota, Region de ValparaisoChile217 km (135 mi)SW of epicenterColina(pop: 146,200)II: Very weakChacabuco, Santiago MetropolitanChile218 km (135 mi)SW of epicenterHacienda La Calera(pop: 49,100)II: Very weakQuillota, Region de ValparaisoChile227 km (141 mi)SW of epicenterQuillota(pop: 67,800)II: Very weakRegion de ValparaisoChile235 km (146 mi)SW of epicenterQuilicura(pop: 210,400)II: Very weakSantiago, Santiago MetropolitanChile236 km (146 mi)SW of epicenterLampa(pop: 102,200)II: Very weakChacabuco, Santiago MetropolitanChile236 km (147 mi)SW of epicenterPenalolen(pop: 241,600)II: Very weakSantiago, Santiago MetropolitanChile238 km (148 mi)SW of epicenterRenca(pop: 147,200)II: Very weakSantiago, Santiago MetropolitanChile240 km (149 mi)SW of epicenterSantiago(pop: 4,837,300)II: Very weakSantiago MetropolitanChile242 km (151 mi)SW of epicenterLo Prado(pop: 104,300)II: Very weakSantiago, Santiago MetropolitanChile248 km (154 mi)SW of epicenterVilla Alemana(pop: 97,300)II: Very weakMarga Marga, Region de ValparaisoChile251 km (156 mi)SW of epicenterMaipu(pop: 503,600)II: Very weakSantiago, Santiago MetropolitanChile252 km (156 mi)SW of epicenterLa Pintana(pop: 201,200)II: Very weakSantiago, Santiago MetropolitanChile252 km (157 mi)SW of epicenterPuente Alto(pop: 568,100)II: Very weakCordillera, Santiago MetropolitanChile253 km (157 mi)SW of epicenterQuilpue(pop: 130,300)II: Very weakMarga Marga, Region de ValparaisoChile255 km (159 mi)SW of epicenterSan Bernardo(pop: 249,900)II: Very weakMaipo, Santiago MetropolitanChile257 km (160 mi)NW of epicenterLa Serena(pop: 154,500)II: Very weakProvincia de Elqui, Region de CoquimboChile259 km (161 mi)SW of epicenterVina del Mar(pop: 334,200)II: Very weakValparaiso, Region de ValparaisoChile259 km (161 mi)NW of epicenterCoquimbo(pop: 161,300)II: Very weakProvincia de Elqui, Region de CoquimboChile266 km (165 mi)SW of epicenterValparaiso(pop: 282,400)II: Very weakValparaiso, Region de ValparaisoChile342 km (212 mi)NE of epicenterLa Rioja(pop: 178,900)II: Very weakDepartamento de Capital, La Rioja ProvinceArgentina345 km (215 mi)SE of epicenterSan Luis(pop: 169,900)II: Very weakJuan Martin de Pueyrredon, San Luis ProvinceArgentinaNotes:(*) 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 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)Jan 15, 2026 08:30 am (Universal Time)4 minutes ago4.7195 km0 km - This quakeDepartamento de Calingasta, San Juan Province, ArgentinaMain 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 1,300 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.07 quakes per year (or 1 quake every 14.1 years)Mag. 5 or higher: 1.34 quakes per yearMag. 4 or higher: 28.9 quakes per yearMag. 3 or higher: 377 quakes per year (or 31.4 quakes per month)Mag. 2 or higher: 1,300 quakes per year (or 3.4 quakes per day)Mag. 1 or higher: 1,300 quakes per year (or 3.5 quakes per day)The area where this quake occurred has a high level of seismic activity. It has had at least 9 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 10 to 15 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
