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, 507 km (315 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(*)RegionCountry55 km (34 mi)N of epicenterHuasco(pop: 8,980)II: Very weakRegion de AtacamaChile56 km (35 mi)NE of epicenterFreirina(pop: 6,040)II: Very weakHuasco, Region de AtacamaChile66 km (41 mi)S of epicenterLa Higuera(pop: 4,290)II: Very weakProvincia de Elqui, Region de CoquimboChile72 km (45 mi)NE of epicenterVallenar(pop: 44,900)II: Very weakHuasco, Region de AtacamaChile88 km (55 mi)E of epicenterAlto del Carmen(pop: 5,030)II: Very weakHuasco, Region de AtacamaChile108 km (67 mi)S of epicenterLa Serena(pop: 154,500)II: Very weakProvincia de Elqui, Region de CoquimboChile113 km (70 mi)S of epicenterCoquimbo(pop: 161,300)II: Very weakProvincia de Elqui, Region de CoquimboChile137 km (85 mi)SE of epicenterVicuna(pop: 27,800)II: Very weakProvincia de Elqui, Region de CoquimboChile147 km (91 mi)S of epicenterAndacollo(pop: 11,100)II: Very weakProvincia de Elqui, Region de CoquimboChile147 km (91 mi)SE of epicenterPaiguano(pop: 4,260)II: Very weakProvincia de Elqui, Region de CoquimboChile185 km (115 mi)S of epicenterOvalle(pop: 77,100)I: Not feltProvincia de Limari, Region de CoquimboChile197 km (122 mi)NE of epicenterTierra Amarilla(pop: 12,900)I: Not feltCopiapo, Region de AtacamaChile199 km (124 mi)S of epicenterMonte Patria(pop: 13,900)I: Not feltProvincia de Limari, Region de CoquimboChile202 km (126 mi)NE of epicenterCopiapo(pop: 129,300)I: Not feltCopiapo, Region de AtacamaChile202 km (126 mi)NE of epicenterCopiapo(pop: 129,300)I: Not feltCopiapo, Region de AtacamaChile211 km (131 mi)S of epicenterPunitaqui(pop: 10,400)I: Not feltProvincia de Limari, Region de CoquimboChile215 km (134 mi)N of epicenterCaldera(pop: 16,200)I: Not feltCopiapo, Region de AtacamaChile252 km (156 mi)S of epicenterCombarbala(pop: 13,600)I: Not feltProvincia de Limari, Region de CoquimboChile292 km (182 mi)SE of epicenterSan Jose de Jachal(pop: 21,000)I: Not feltDepartamento de Jachal, San Juan ProvinceArgentina326 km (202 mi)SE of epicenterCalingasta(pop: 8,180)I: Not feltSan Juan ProvinceArgentina390 km (242 mi)SE of epicenterAlbardon(pop: 20,400)I: Not feltDepartamento de Albardon, San Juan ProvinceArgentina390 km (243 mi)SE of epicenterVilla General San Martin(pop: 10,100)I: Not feltDepartamento de San Martin, San Juan ProvinceArgentina507 km (315 mi)S of epicenterSantiago(pop: 4,837,300): Not feltSantiago MetropolitanChileNotes:(*) 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!Get the Android appCompare 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.

It has had at least 25 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 5 to 10 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
