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 390 thousand people exposed to shaking
An estimated 390 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 III, which corresponds with weak shaking and probably no damage. Roughly 23,050 people are expected to be exposed to this level. Intensity level II was experienced by the majority of people (around 370 thousand). In their region, very weak shaking and no damage can be expected. All exposure to shaking was within the borders of Papua New Guinea .

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.
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.
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 very common in the region. This is the strongest earthquake to hit since April 14th, 2024, when a 6.5 magnitude earthquake hit 192 km (119 mi) further south-east. An even stronger magnitude 7.6 earthquake struck on May 14th, 2019.
In total, 46 earthquakes with a magnitude of 6 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 3 months.
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. Earthquakes of this strength are unlikely to trigger a tsunami. |
Not this earthquake. This earthquake occurred at a depth of 521 km (324 mi). Earthquakes this deep in the earth are unlikely to trigger a tsunami. |
