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 650 thousand people exposed to shaking
The USGS has published a report estimating the number of people exposed to this earthquake. Acoording to their analysis, roughly 650 thousand have been exposed to shaking at an MMI level of II or higher.
Moderate shaking and very light damage may have been experienced by an estimated 2,130 people. At V, it is the highest MMI level this earthquake has caused. Intensity level IV was experienced by the majority of people (around 420 thousand). In their region, light shaking and likely no damage can be expected.
People in 2 countries have been exposed to shaking. Roughly 650 thousand people were exposed to shaking in Chile , with level V (moderate shaking, very light damage) as the highest recorded. In Argentina, shaking was experienced too.

Aftershocks detected
In the days before this main shock, 2 smaller foreshocks were detected. Nearby this earthquake a foreshock struck 2 days earlier. It measured a magnitude of 2.9

More earthquakes coming?
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.
It's always adviced to be cautious of the risk of a larger shock following any significant earthquake, however this risk is fairly small. There is a roughly 94 percent change that no larger main shock will follow in the days following this earthquake.

Earthquakes of this strength are very common in the region. This is the strongest earthquake to hit since April 18th, 2025, when a 5.6 magnitude earthquake hit 247 km (154 mi) further east. An even stronger magnitude 7.4 earthquake struck on July 19th, 2024.
In total, 33 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 4 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.
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 on land near a coastal area (4 km from 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 52 km (33 mi). Earthquakes this shallow could trigger a tsunami. |
