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 140 thousand people exposed to shaking
An estimated 140 thousand have been exposed to shaking (An MMI or Modified Mercalli Intensity level II or higher) as a result of this earthquake according scientific estimates published by the USGS.
The highest earthquake impact level for this earthquake is IV, which corresponds with light shaking and likely no damage. Roughly 5,680 people are expected to be exposed to this level. The majority of people (roughly 1.3 million) live in an area exposed to level I, where not noticeable and no damage is expected.

Risk of aftershocks?
We have not yet detected any foreshocks or aftershocks (MAG-2.5 or higher) within 100km (62 mi) of this earthquake.
Earthquakes can create aftershocks. These are generally at least 1 magnitude lower than any main shock, and as time passes the chance and strength of aftershocks decreases.
In only six percent of cases, significant earthquakes are followed by a larger main shock, making the current earthquake a foreshock. While the chance of this happening is not so large, it is adviced to maintain cautiousness in the hours and days following a major earthquake.

Earthquakes of this strength are very common in the region. This is the strongest earthquake to hit since April 12th, 2024, when a 4 magnitude earthquake hit 74 mi (120 km) further west-southwest. An even stronger magnitude 6.6 earthquake struck on December 8th, 2016.
In total, 217 earthquakes with a magnitude of 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 17 days.
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 (14 mi from the sea). | Not this earthquake. This earthquake had a magnitude of 4. Earthquakes of this strength are unlikely to trigger a tsunami. |
This earthquake occurred at a depth of of 16 mi (26 km). Earthquakes this shallow could trigger a tsunami. |
