People likely experienced 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, 107 km (67 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(*)RegionCountry4 km (2 mi)NW of epicenterQuintero(pop: 31,900)III: WeakValparaiso, Region de ValparaisoChile13 km (8 mi)S of epicenterConcon(pop: 42,200)III: WeakValparaiso, Region de ValparaisoChile24 km (15 mi)S of epicenterVina del Mar(pop: 334,200)III: WeakValparaiso, Region de ValparaisoChile25 km (15 mi)E of epicenterQuillota(pop: 67,800)III: WeakRegion de ValparaisoChile26 km (16 mi)E of epicenterLa Cruz(pop: 17,300)III: WeakQuillota, Region de ValparaisoChile27 km (17 mi)E of epicenterHacienda La Calera(pop: 49,100)III: WeakQuillota, Region de ValparaisoChile27 km (17 mi)S of epicenterQuilpue(pop: 130,300)III: WeakMarga Marga, Region de ValparaisoChile28 km (17 mi)SW of epicenterValparaiso(pop: 282,400)III: WeakValparaiso, Region de ValparaisoChile28 km (18 mi)E of epicenterLa Calera(pop: 50,200)III: WeakQuillota, Region de ValparaisoChile29 km (18 mi)SE of epicenterVilla Alemana(pop: 97,300)III: WeakMarga Marga, Region de ValparaisoChile32 km (20 mi)SE of epicenterLimache(pop: 46,100)III: WeakMarga Marga, Region de ValparaisoChile47 km (29 mi)NE of epicenterLa Ligua(pop: 32,100)III: WeakPetorca, Region de ValparaisoChile48 km (30 mi)NE of epicenterCatemu(pop: 13,300)III: WeakSan Felipe de Aconcagua, Region de ValparaisoChile51 km (32 mi)E of epicenterLlaillay(pop: 22,700)III: WeakSan Felipe de Aconcagua, Region de ValparaisoChile57 km (35 mi)S of epicenterCasablanca(pop: 24,500)II: Very weakValparaiso, Region de ValparaisoChile58 km (36 mi)NE of epicenterCabildo(pop: 19,300)II: Very weakPetorca, Region de ValparaisoChile61 km (38 mi)SE of epicenterTiltil(pop: 19,300)II: Very weakChacabuco, Santiago MetropolitanChile62 km (39 mi)E of epicenterPanquehue(pop: 6,840)II: Very weakSan Felipe de Aconcagua, Region de ValparaisoChile64 km (40 mi)S of epicenterAlgarrobo(pop: 10,200)II: Very weakSan Antonio, Region de ValparaisoChile73 km (45 mi)E of epicenterSan Felipe(pop: 59,300)II: Very weakRegion de ValparaisoChile76 km (47 mi)E of epicenterPutaendo(pop: 15,400)II: Very weakSan Felipe de Aconcagua, Region de ValparaisoChile79 km (49 mi)SE of epicenterLampa(pop: 102,200)II: Very weakChacabuco, Santiago MetropolitanChile82 km (51 mi)E of epicenterCalle Larga(pop: 13,400)II: Very weakLos Andes, Region de ValparaisoChile83 km (52 mi)S of epicenterCartagena(pop: 18,000)II: Very weakSan Antonio, Region de ValparaisoChile84 km (52 mi)E of epicenterLos Andes(pop: 63,000)II: Very weakRegion de ValparaisoChile86 km (53 mi)E of epicenterSan Esteban(pop: 17,100)II: Very weakLos Andes, Region de ValparaisoChile88 km (55 mi)S of epicenterSan Antonio(pop: 87,700)II: Very weakRegion de ValparaisoChile89 km (55 mi)SE of epicenterColina(pop: 146,200)II: Very weakChacabuco, Santiago MetropolitanChile95 km (59 mi)SE of epicenterChicureo Abajo(pop: 18,000)II: Very weakChacabuco, Santiago MetropolitanChile96 km (60 mi)SE of epicenterQuilicura(pop: 210,400)II: Very weakSantiago, Santiago MetropolitanChile99 km (62 mi)SE of epicenterRenca(pop: 147,200)II: Very weakSantiago, Santiago MetropolitanChile100 km (62 mi)N of epicenterLos Vilos(pop: 18,300)II: Very weakProvincia de Choapa, Region de CoquimboChile101 km (63 mi)SE of epicenterLo Prado(pop: 104,300)II: Very weakSantiago, Santiago MetropolitanChile101 km (63 mi)S of epicenterMelipilla(pop: 63,100)II: Very weakSantiago MetropolitanChile104 km (65 mi)SE of epicenterMaipu(pop: 503,600)II: Very weakSantiago, Santiago MetropolitanChile107 km (67 mi)SE of epicenterSantiago(pop: 4,837,300)II: Very weakSantiago MetropolitanChile114 km (71 mi)SE of epicenterSan Bernardo(pop: 249,900)II: Very weakMaipo, Santiago MetropolitanChile116 km (72 mi)SE of epicenterPenalolen(pop: 241,600)II: Very weakSantiago, Santiago MetropolitanChile118 km (73 mi)SE of epicenterLa Pintana(pop: 201,200)II: Very weakSantiago, Santiago MetropolitanChile124 km (77 mi)SE of epicenterPuente Alto(pop: 568,100)II: Very weakCordillera, Santiago MetropolitanChileNotes:(*) Shaking intensity according to the Modified Mercalli Intensity Scale (MMI) and estimated using seismic models.User-reports for this quake (12)The first report about ground shaking reached us after only 1 minute, before other agencies reported it. So far, we have received 12 reports for this quake from Chile. The quake was reported to have been felt in up to approx. 70–120 km (43–75 mi) distance, with isolated cases to have felt the quake even 167 km (104 mi) away.The majority of reports came from Santiago (4 reports), the capital of Chile with 4,800,000 inhabitants in 107 km (67 mi) distance southeast of the epicenter, San Antonio (1 report), a town with 88,000 inhabitants in Region de Valparaiso in 88 km (55 mi) distance south of the epicenter, and Colina (1 report) (89 km or 55 mi to the southeast) in Santiago Metropolitan.

It is commonly measured on the so-called Modified Mercalli Intensity Scale (MMI) ranging from 1 (not felt) to 10 (extreme shaking), and given in Roman numerals as I,II,...IX, X, and often displayed with color codes ranging from light blue to dark red.Earthquake intensity depends mainly on the magnitude and depth of the quake as well as the distance from the epicenter: The further away, the less shaking intensity occurs.Read more about the MMI scale!Number of reports by intensityShaking intensityNumber of reportsMin-Max distance from epicenter (*)Average distance (*)II: Very weak shaking325–98 km (15.8–61 mi)71 km (44 mi)III: Weak shaking613.8–119 km (8.6–74 mi)73 km (45 mi)IV: Light shaking221–104 km (13.2–65 mi)63 km (39 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (12 in total) could be used for geographic statistics.Get the Android appI didn't feel itI felt this quakeIf you were near the epicenter and felt it, please share your experience and submit a short "I felt it" report!

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)Sep 29, 2026 01:02 am (Santiago)6 minutes ago - felt4.258 km0 km - This quake24 km N of Vina del Mar, Valparaiso, Region de Valparaiso, ChileMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake
