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 370 thousand people exposed to shaking

The USGS has published a report estimating the number of people exposed to this earthquake. Acoording to their analysis, roughly 370 thousand have been exposed to shaking at an MMI level of II or higher.

An estimated 0 people were exposed to level V. At this level, moderate shaking and very light damage can be expected. Intensity level IV was experienced by the majority of people (around 360 thousand). In their region, light shaking and likely no damage can be expected.

People in 2 countries have been exposed to shaking. Roughly 370 thousand people were exposed to shaking in Papua New Guinea , with level V (moderate shaking, very light damage) as the highest recorded. People were exposed to shaking in Solomon Islands as well.

Nearby towns and cities

This earthquake may have been felt in Papua New Guinea . Arawa in Bougainville, Papua New Guinea is the nearest significant place from the epicenter. The earthquake occurred 185 kilometer (115 mi) west-northwest of Arawa. The intensity of shaking and damage in Arawa is estimated to be around level IV on the Modified Mercalli Intensity scale (light shaking, likely no damage).

Risk of aftershocks?

This earthquake did not have any significant foreshocks nor aftershocks occurring within 100km (62 mi) of its epicenter.

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 like this happen often in the region

Earthquakes of this strength are very common in the region. This is the strongest earthquake to hit since March 8th, 2023, when a 5.8 magnitude earthquake hit 157 km (98 mi) further south-east. An even stronger magnitude 7.9 earthquake struck on January 22nd, 2017.

In total, 61 earthquakes with a magnitude of 5.7 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 2 months.

Tsunami very unlikely

DISCLAIMER: We strongly suggest to closely monitor advice from local authorities with regards to tsunami risks. Our analysis is based on automatically collected data from external sources, and these might contain mistakes. In addition, earthquakes can cause landslides that may lead to a tsunami, or be a followed by another, potentially stonger, earthquake.

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 5.7. Earthquakes of this strength are unlikely to trigger a tsunami.
Not this earthquake.
This earthquake occurred at a depth of 125 km (78 mi). Earthquakes this deep in the earth are unlikely to trigger a tsunami.
