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 69% likelyhood of between 0 and 1 fatalities, and a 98% 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 1.6 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 1.6 million have been exposed to shaking at an MMI level of II or higher.
The highest earthquake impact level for this earthquake is V, which corresponds with moderate shaking and very light damage. Roughly 4,990 people are expected to be exposed to this level. The majority of people (roughly 1 million) live in an area exposed to level III, where weak shaking and probably no damage is expected.

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.
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 not so common in the region, but it's not the first time. This is the strongest earthquake to hit since December 16th, 2022, when a 5.2 magnitude earthquake hit 95 mi (153 km) further west-southwest. That was also the heaviest earthquake to hit the region in the past 10 years.
In total, 1 earthquake with a magnitude of 4.9 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 10 years.
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 | Not this earthquake. This earthquake appears to have struck on land far from any coast. |
Not this earthquake. This earthquake had a magnitude of 4.9. Earthquakes of this strength are unlikely to trigger a tsunami. |
This earthquake occurred at a depth of of 2 mi (3 km). Earthquakes this shallow could trigger a tsunami. |
