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 Peru, Lima, 929 km (577 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(*)RegionCountry78 km (48 mi)NE of epicenterIte(pop: 998)II: Very weakJorge Basadre, TacnaPeru80 km (50 mi)NE of epicenterVila Vila(pop: 474)II: Very weakTacna, TacnaPeru87 km (54 mi)N of epicenterIlo(pop: 53,500)II: Very weakDepartamento de MoqueguaPeru96 km (60 mi)NE of epicenterEl Huayco(pop: 30)II: Very weakTacna, TacnaPeru98 km (61 mi)E of epicenterLos Olivos(pop: 484)II: Very weakTacna, TacnaPeru105 km (65 mi)E of epicenterLos Palos(pop: 207)II: Very weakTacna, TacnaPeru109 km (68 mi)NE of epicenterLas Yaras(pop: 585)II: Very weakTacna, TacnaPeru113 km (70 mi)NE of epicenterLocumba(pop: 993)II: Very weakJorge Basadre, TacnaPeru118 km (74 mi)E of epicenterArica(pop: 241,700)II: Very weakRegion de Arica y ParinacotaChile119 km (74 mi)NE of epicenterSama Grande(pop: 826)II: Very weakTacna, TacnaPeru123 km (77 mi)NE of epicenterChironta(pop: 34)II: Very weakJorge Basadre, TacnaPeru130 km (81 mi)NE of epicenterYarascay(pop: 109)II: Very weakTacna, TacnaPeru130 km (81 mi)NE of epicenterOconchay(pop: 99)II: Very weakJorge Basadre, TacnaPeru131 km (81 mi)E of epicenterTacna(pop: 286,200)II: Very weakTacnaPeru132 km (82 mi)N of epicenterChamac(pop: 47)II: Very weakProvincia de Mariscal Nieto, Departamento de MoqueguaPeru135 km (84 mi)NE of epicenterCaoña(pop: 12)II: Very weakJorge Basadre, TacnaPeru140 km (87 mi)E of epicenterCalana(pop: 875)II: Very weakTacna, TacnaPeru143 km (89 mi)N of epicenterSan Antonio(pop: 15,600)II: Very weakProvincia de Mariscal Nieto, Departamento de MoqueguaPeru143 km (89 mi)N of epicenterPunta de Bombon(pop: 6,340)II: Very weakIslay, ArequipaPeru144 km (90 mi)N of epicenterMoquegua(pop: 69,900)II: Very weakProvincia de Mariscal Nieto, Departamento de MoqueguaPeru146 km (91 mi)NE of epicenterIlabaya(pop: 9,490)II: Very weakJorge Basadre, TacnaPeru150 km (93 mi)NE of epicenterCalientes(pop: 231)II: Very weakTacna, TacnaPeru151 km (94 mi)N of epicenterCocachacra(pop: 8,800)II: Very weakIslay, ArequipaPeru154 km (96 mi)N of epicenterMejia(pop: 683)II: Very weakIslay, ArequipaPeru158 km (98 mi)NE of epicenterTotorales(pop: 1,980)II: Very weakCandarave, TacnaPeru160 km (99 mi)N of epicenterEl Toro(pop: 206)II: Very weakIslay, ArequipaPeru160 km (100 mi)N of epicenterTorata(pop: 7,050)II: Very weakProvincia de Mariscal Nieto, Departamento de MoqueguaPeru163 km (101 mi)NE of epicenterChipispaya(pop: 1,930)II: Very weakTarata, TacnaPeru164 km (102 mi)NE of epicenterTala(pop: 85)II: Very weakProvincia de Mariscal Nieto, Departamento de MoqueguaPeru167 km (104 mi)NW of epicenterMollendo(pop: 29,000)II: Very weakIslay, ArequipaPeru168 km (104 mi)NE of epicenterCairani(pop: 604)II: Very weakCandarave, TacnaPeru172 km (107 mi)E of epicenterVilavilani(pop: 321)II: Very weakTacna, TacnaPeru176 km (110 mi)NE of epicenterCaplina(pop: 211)II: Very weakTacna, TacnaPeru177 km (110 mi)NE of epicenterAsana(pop: 50)II: Very weakProvincia de Mariscal Nieto, Departamento de MoqueguaPeru177 km (110 mi)NE of epicenterCandarave(pop: 3,420)II: Very weakTacnaPeru178 km (111 mi)NE of epicenterSitajara(pop: 451)I: Not feltTarata, TacnaPeru179 km (111 mi)NE of epicenterPujocucho(pop: 4,120)I: Not feltCandarave, TacnaPeru180 km (112 mi)NE of epicenterTarata(pop: 3,050)I: Not feltTacnaPeru192 km (119 mi)NE of epicenterChuquitira(pop: 4,220)I: Not feltTarata, TacnaPeru929 km (577 mi)NW of epicenterLima(pop: 7,737,000): Not feltLima ProvincePeruNotes:(*) 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.

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)Apr 17, 2026 03:54 am (Universal Time)8 minutes ago4.033 km0 km - This quakePeru: Off Coast OF Tarapaca, ChileMain 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 76 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.06 quakes per year (or 1 quake every 16.4 years)Mag. 5 or higher: 1.2 quakes per yearMag. 4 or higher: 11.7 quakes per yearMag. 3 or higher: 43 quakes per year (or 3.6 quakes per month)Mag. 2 or higher: 76 quakes per year (or 6.3 quakes per month)The area where this quake occurred has a high level of seismic activity. It has had at least 4 quakes above magnitude 6 since 1970, 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
