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 80 thousand people exposed to shaking
This earthquake may have been felt by around 80 thousand people. That is the expected population size of the area exposed to a level of shaking of II or higher on the Modified Mercalli scale according to the USGS.
Very weak shaking and no damage may have been experienced by an estimated 79,860 people. At II, it is the highest MMI level this earthquake has caused. All exposure to shaking was within the borders of Indonesia .

Currently, 3 people have reported shaking in 3 places in 2 countries (Australia, Indonesia).We keep updating this article as more ground reports become available. You may report that you felt this earthquake here.

- Bau Bau, Sulawesi Tenggara, Indonesia: 1 person.
Risk of aftershocks?
We have not yet detected any foreshocks or aftershocks (MAG-2.5 or higher) within 100km (62 mi) of this earthquake.
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.
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 occur quite regularly in the region. This is the strongest earthquake to hit since April 22nd, 2023, when a 6.2 magnitude earthquake hit 110 km (69 mi) further north-east. An even stronger magnitude 6.9 earthquake struck on August 21st, 2020.
In total, 7 earthquakes with a magnitude of 6.1 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 year.
Tsunami very unlikely
For a serious tsunami to occur, earthquakes usually need to have a magnitude of at least 6.5 and occur at a shallow depth of maximum 100km. Neither are the case with this earthquake. 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 under the sea. | Not this earthquake. This earthquake had a magnitude of 6.1. Earthquakes of this strength are unlikely to trigger a tsunami. |
Not this earthquake. This earthquake occurred at a depth of 588 km (365 mi). Earthquakes this deep in the earth are unlikely to trigger a tsunami. |
