Earthquake Summary
The earthquake struck on land in Solomon Islands, 102 kilometer (63 mi) south-southeast of Arawa in Bougainville. The center of this earthquake had a very shallow depth of 10 km. Shallow earthquakes usually have a larger impact than earthquakes deep in the earth.

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 400 thousand people exposed to shaking
An estimated 400 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.
Strong shaking and probably light damage may have been experienced by an estimated 30 people. At VI, it is the highest MMI level this earthquake has caused. The majority of people (roughly 250 thousand) live in an area exposed to level III, where weak shaking and probably no damage is expected.
People in 2 countries have been exposed to shaking. In Papua New Guinea , around 280 thousand people, with impact levels up to VI (strong shaking, probably light damage). In Solomon Islands , around 120 thousand people.

Nearby towns and cities
This earthquake may have been felt in Papua New Guinea . The closest significant population center near the earthquake is Arawa in Bougainville, Papua New Guinea. Arawa is located 102 kilometer (63 mi) south-southeast of the epicenter. The intensity of shaking and damage in Arawa is estimated to be around level III on the Modified Mercalli Intensity scale (weak shaking, probably no damage).

Aftershocks detected
Since this main shock, 1 smaller aftershock was detected. At a distance of 79 km (49 mi) west of this earthquake, an aftershock struck 11 hrs later. It measured a magnitude of 5
Overview of foreshocks and aftershocks
Classification | Magnitude | When | Where |
---|---|---|---|
Main Shock This Earthquake |
M 5.4 |
Feb 10, 2025 11:28 (Bougainville Time) | - |
Aftershock | M 5.0 |
11 hrs later Feb 10, 2025 22:17 (Bougainville Time) | 79 km (49 mi) W from Main Shock. |
More earthquakes coming?
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.
The chance that a significant earthquake like this one is followed by an even larger earthquake is not so large. On average, scientists estimate a 94% chance that a major earthquake will not be followed by an even larger one. It is still adviced to be aware of this risk

Earthquakes of this strength are very common in the region. This is the strongest earthquake to hit since September 1st, 2024, when a 6.4 magnitude earthquake hit 42 km (26 mi) further northwest. An even stronger magnitude 7.9 earthquake struck on January 22nd, 2017.
In total, 56 earthquakes with a magnitude of 5.4 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.
Low tsunami risk
Based on early data it appears this earthquake was not strong enough (lower than MAG-6.5) to be likely to cause destructive tsunami's. However this earthquake appeared to have hit at a shallow depth under sea, so 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 5.4. 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. |
