Minimal impact predicted

Based on scientific estimates by the US Geographic Survey (USGS), the risk of high fatalities for this earthquake is classified at level GREEN (low). They expect an 65% likelyhood of between 0 and 1 fatalities, and a 96% chance that the number of fatalities falls no higher than 10.

The USGS classifies the economic impact of this earthquake at level GREEN (low). They expect an 65% likelyhood of between 0 and 1 million US Dollars in economic damage and impact, and a 96% chance that the economic impact of this earthquake falls no higher than 10 million USD.

Roughly 300 thousand people exposed to shaking

This earthquake may have been felt by around 300 thousand people. That is the expected population size of the area exposed to a level of shaking of II or higher on the Modified Mercalli scale according to the USGS.

Light shaking and likely no damage may have been experienced by an estimated 43,750 people. At IV, it is the highest MMI level this earthquake has caused. Intensity level III was experienced by the majority of people (around 240 thousand). 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 . Minas de Marcona in Ica, Peru is the nearest significant place from the epicenter. The earthquake occurred 95 kilometer (59 mi) south-southeast of Minas de Marcona. The intensity of shaking and damage in Minas de Marcona is estimated to be around level IV on the Modified Mercalli Intensity scale (light shaking, likely no damage).

An overview of nearby towns and cities is available in the overview below. If places don't have intensity data available, it likely means the experienced impact in those places was fairly small.

5 Aftershocks detected

This main shock was followed by 5 smaller aftershocks. Just 5 hrs after this main shock, an earthquake measuring MAG-4.5 was detected 20 km (12 mi) west-southwest of this earthquake.

This main shock was prefaced by 4 smaller foreshocks. Roughly 5 hrs before this earthquake, a foreshock measuring MAG-5.3 was detected nearby this earthquake.

More earthquakes coming?

The risk of aftershocks decreases rapidly over time. Usually, aftershocks are at least one order of magnitude lower than a main shock.

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 June 29th, 2024, when a 5.4 magnitude earthquake hit 19 km (12 mi) further east. An even stronger magnitude 7.2 earthquake struck on June 28th, 2024.

In total, 35 earthquakes with a magnitude of 5.4 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 3 months.

Low tsunami risk

DISCLAIMER: We strongly suggest to closely monitor advice from local authorities with regards to tsunami risks. Our analysis is based on automatically collected data from external sources, and these might contain mistakes. In addition, earthquakes can cause landslides that may lead to a tsunami, or be a followed by another, potentially stonger, earthquake.

Based on early data it appears this earthquake was not strong enough (lower than MAG-6.5) to be likely to cause destructive tsunami's. However this earthquake appeared to have hit at a shallow depth under sea, so stay cautious and monitor advice from local authorities.

Tsunami Risk Factors

Factor Under Sea? MAG-6.5 or stronger? Shallow depth?
Explanation Almost all tsunami's are caused by earthquakes with their epicenter under sea or very near the sea. However stay cautious in coastal areas as earthquakes on land may cause landslides into sea, potentially still causing a local tsunami. Under MAG 6.5: Very unlikely to cause a tsunami.
MAG 6.5 to 7.5: Destructive tsunami's do occur, but are uncommon. Likely to observe small sea level changes.
MAG 7.6+: Earthquakes with these magnitudes might produce destructive tsunami's.
Most destructive tsunami's are caused by shallow earthquakes with a depth between 0 and 100km under the surface of the earth. Deeper tsunami's are unlikely to displace to ocean floor.
This Earthquake This earthquake appears to have struck under the sea. Not this earthquake.
This earthquake had a magnitude of 5.4. Earthquakes of this strength are unlikely to trigger a tsunami.
This earthquake occurred at a depth of of 32 km (20 mi). Earthquakes this shallow could trigger a tsunami.
