Risk of aftershocks?
We monitor for foreshocks or aftershocks that have a magnitude of 2.5+ and occur within 100km (62 mi) of the epicenter of this earthquake. So far no such earthquakes have been detected.
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 not so common in the region, but it's not the first time. This is the strongest earthquake to hit since January 17th, 2022, when a 5 magnitude earthquake hit 297 km (184 mi) 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 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 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 5. Earthquakes of this strength are unlikely to trigger a tsunami. |
This earthquake occurred at a depth of of 10 km (6 mi). Earthquakes this shallow could trigger a tsunami. |
