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 Peru, Lima, 208 km (130 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(*)RegionCountry67 km (42 mi)NE of epicenterGramadal(pop: 31)III: WeakHuarmey, AncashPeru69 km (43 mi)E of epicenterParamonga(pop: 27,600)III: WeakBarranca, Lima regionPeru74 km (46 mi)E of epicenterPativilca(pop: 13,600)II: Very weakBarranca, Lima regionPeru75 km (46 mi)E of epicenterBarranca(pop: 46,300)II: Very weakLima regionPeru77 km (48 mi)E of epicenterSupe Puerto(pop: 11,500)II: Very weakBarranca, Lima regionPeru81 km (50 mi)E of epicenterSupe(pop: 13,700)II: Very weakBarranca, Lima regionPeru84 km (52 mi)NE of epicenterHuaricanga(pop: 167)II: Very weakBarranca, Lima regionPeru87 km (54 mi)N of epicenterHuarmey(pop: 16,200)II: Very weakAncashPeru95 km (59 mi)E of epicenterPando(pop: 19)II: Very weakBarranca, Lima regionPeru97 km (61 mi)E of epicenterHualmay(pop: 26,700)II: Very weakHuaura, Lima regionPeru98 km (61 mi)E of epicenterHuaura(pop: 20,700)II: Very weakLima regionPeru98 km (61 mi)E of epicenterHuaura(pop: 20,700)II: Very weakLima regionPeru99 km (61 mi)E of epicenterHuacho(pop: 54,500)II: Very weakHuaura, Lima regionPeru101 km (63 mi)E of epicenterCochas(pop: 211)II: Very weakOcros, AncashPeru108 km (67 mi)N of epicenterMolino(pop: 277)II: Very weakHuarmey, AncashPeru113 km (70 mi)E of epicenterCaldera(pop: 537)II: Very weakHuaura, Lima regionPeru115 km (72 mi)NE of epicenterCopa(pop: 491)II: Very weakOcros, AncashPeru121 km (75 mi)NE of epicenterLlacllin(pop: 723)II: Very weakProvincia de Recuay, AncashPeru123 km (76 mi)E of epicenterOcros(pop: 840)II: Very weakAncashPeru129 km (80 mi)E of epicenterAmbar(pop: 462)II: Very weakHuaura, Lima regionPeru131 km (81 mi)NE of epicenterCajacay(pop: 636)II: Very weakBolognesi, AncashPeru131 km (81 mi)NE of epicenterCoris(pop: 453)II: Very weakAija, AncashPeru142 km (88 mi)E of epicenterSayan(pop: 6,200)II: Very weakHuaura, Lima regionPeru143 km (89 mi)E of epicenterLlipa(pop: 627)II: Very weakOcros, AncashPeru145 km (90 mi)NE of epicenterAija(pop: 843)II: Very weakAncashPeru148 km (92 mi)NE of epicenterCorpanqui(pop: 597)II: Very weakBolognesi, AncashPeru156 km (97 mi)SE of epicenterChancay(pop: 27,000)II: Very weakHuaral, Lima regionPeru157 km (97 mi)SE of epicenterHuaral(pop: 62,200)II: Very weakLima regionPeru162 km (101 mi)N of epicenterHuanchuy(pop: 695)II: Very weakCasma, AncashPeru163 km (101 mi)NE of epicenterPacllon(pop: 892)II: Very weakBolognesi, AncashPeru163 km (102 mi)NE of epicenterAquia(pop: 809)II: Very weakBolognesi, AncashPeru173 km (107 mi)NE of epicenterHuaraz(pop: 118,800)II: Very weakAncashPeru174 km (108 mi)NE of epicenterCentenario(pop: 47,600)II: Very weakHuaraz, AncashPeru202 km (126 mi)SE of epicenterCallao(pop: 1,300,000)II: Very weakCallaoPeru204 km (127 mi)SE of epicenterCarmen De La Legua Reynoso(pop: 41,900)II: Very weakCallao, CallaoPeru207 km (129 mi)SE of epicenterBrena(pop: 81,900)II: Very weakLima, Lima regionPeru208 km (130 mi)SE of epicenterLima(pop: 7,737,000)II: Very weakLima ProvincePeru209 km (130 mi)SE of epicenterJesus Maria(pop: 66,200)II: Very weakLima, Lima regionPeru211 km (131 mi)SE of epicenterSan Isidro(pop: 68,300)II: Very weakLima, Lima regionPeru214 km (133 mi)SE of epicenterSan Francisco De Borja(pop: 105,100)II: Very weakLima, Lima regionPeruNotes:(*) 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 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)Aug 3, 2025 05:21 pm (GMT -5)17 minutes ago4.228 km0 km - This quakeSouth Pacific Ocean, 75 km W of Barranca, Lima region, PeruMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 55 years and our earthquake archive back to 1900, there are about 14.5 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.1 quakes per year (or 1 quake every 9.6 years)Mag. 5 or higher: 1.18 quakes per yearMag. 4 or higher: 12.1 quakes per yearMag. 3 or higher: 13.8 quakes per yearMag. 2 or higher: 13.8 quakes per yearThe area where this quake occurred has a very high level of seismic activity. It has had at least 13 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 earthquakeThe earthquake occurred 36 weeks after a magnitude 4.3 earthquake had hit on Thursday, Nov 28, 2024, at 01:46 am (GMT -5 local time) in 93 km (58 mi) distance to the north:Mag. 4.3 earthquake South Pacific Ocean - Ancash, Peru - Nov 28, 2024 - The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 5.4.
