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.
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 May 10th, 2026, when a 5.3 magnitude earthquake hit 250 km (156 mi) further northwest. An even stronger magnitude 7.6 earthquake struck on September 10th, 2022.
In total, 213 earthquakes 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 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 | 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 64 km (40 mi). Earthquakes this shallow could trigger a tsunami. |
