Earthquake Summary

This earthquake hit under water in the South Pacific Ocean, 198 kilometers (123 mi) off the coast of Fiji, 331 kilometer east of Suva in Central. The center of this earthquake had a very deep depth of 592 km. Deep earthquakes usually have less impact than shallower earthquakes of similar strenght.

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 3 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 3 thousand have been exposed to shaking at an MMI level of II or higher.

An estimated 2,860 people were exposed to level II. At this level, very weak shaking and no damage can be expected. Intensity level I was experienced by the majority of people (around 40 thousand). In their region, not noticeable and no damage can be expected. All exposure to shaking was within the borders of Fiji .

2 Aftershocks detected

This main shock was followed by 2 smaller aftershocks. A 4.6 magnitude earthquake hit 2 days later 69 km (43 mi) north-northwest of this earthquake.

Before this earthquake struck, 1 smaller foreshock occurred. Roughly 13 hrs before this earthquake, a foreshock measuring MAG-4.4 was detected nearby this earthquake.

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.

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 November 6th, 2024, when a 5.9 magnitude earthquake hit 62 km (38 mi) further east-southeast. An even stronger magnitude 8.2 earthquake struck on August 19th, 2018.

In total, 39 earthquakes with a magnitude of 5.9 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

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 5.9. Earthquakes of this strength are unlikely to trigger a tsunami.
Not this earthquake.
This earthquake occurred at a depth of 592 km (368 mi). Earthquakes this deep in the earth are unlikely to trigger a tsunami.
