Significant impact predicted

Based on scientific estimates by the US Geographic Survey (USGS), the risk of high fatalities for this earthquake is classified at level YELLOW (significant). They expect an 48% likelyhood of between 10 and 100 fatalities, and a 95% chance that the number of fatalities falls between 1 and 1,000.

The USGS classifies the economic impact of this earthquake at level YELLOW (significant). They expect an 43% likelyhood of between 10 and 100 million US Dollars in economic damage and impact, and a 91% chance that the economic impact of this earthquake falls between 1 and 1,000 million USD.

Roughly 14 million people exposed to shaking

The USGS has published a report estimating the number of people exposed to this earthquake. Acoording to their analysis, roughly 14 million have been exposed to shaking at an MMI level of II or higher.

The highest earthquake impact level for this earthquake is VII, which corresponds with very strong shaking and likely moderate damage. Roughly 377,000 people are expected to be exposed to this level. Intensity level III was experienced by the majority of people (around 13 million). In their region, weak shaking and probably no damage can be expected. All exposure to shaking was within the borders of Peru .

Nearby towns and cities

This earthquake may have been felt in Peru . The closest significant population center near the earthquake is Chilca in Junin, Peru. Chilca is located 11 kilometer (7 mi) west of the epicenter. The intensity of shaking and damage in Chilca is estimated to be around level VII on the Modified Mercalli Intensity scale (very strong shaking, likely moderate damage).

Multiple large cities are in proximity of today's earthquake. Lima is located 188 km to the west and experienced an intensity of III (weak shaking, probably no damage). Huancayo is located 12 km to the east and experienced an intensity of VII (very strong shaking, likely moderate damage). Callao is located 197 km to the west and experienced an intensity of III (weak shaking, probably no damage).

The table below provides an overview of all places in proximity of today's earthquake. Where available, the estimated intensity on the Modified Mercalli Intensity Scale in each place is included. Places where this information is omitted likely experienced little impact.

Shaking reported by 12 people

People that feel an earthquake may report their experience to the US Geographic Survey. Currently, 12 people have reported shaking in 5 places, all within Peru.We keep updating this article as more ground reports become available. You may report that you felt this earthquake here.

Places with most reports:

• Huancayo, Junín, Peru: 5 people.
• Chupaca, Junín, Peru: 4 people.
• Sicaya, Junín, Peru: 1 person.
• Lima, Lima Provincias, Peru: 1 person.

Risk of aftershocks?

This earthquake did not have any significant foreshocks nor aftershocks occurring within 100km (62 mi) of its epicenter.

Aftershocks are usually at least 1 order of magnitude less strong than main shocks. The more time passes, the smaller the chance and likely strength of any potential aftershocks.

The chance that a significant earthquake like this one is followed by an even larger earthquake is not so large. On average, scientists estimate a 94% chance that a major earthquake will not be followed by an even larger one. It is still adviced to be aware of this risk

Earthquakes like this happen often in the region

Earthquakes of this strength are very common in the region. This is the strongest earthquake to hit since May 19th, 2026, when a 5.8 magnitude earthquake hit 233 km (145 mi) further south. An even stronger magnitude 5.9 earthquake struck on October 28th, 2022.

In total, 15 earthquakes with a magnitude of 5.5 or higher have been registered within 300km (186 mi) of this epicenter in the past 10 years. This comes down to an average of once every 8 months.

Tsunami very unlikely

While MAG-6.5+ earthquakes may cause tsunami's, it appears that the epicenter of this earthquake hit under land. In addition, the reported depth is deeper than 100km, making the risk of a tsunami even less likely. However always stay cautious and monitor advice from local authorities.
