Earthquake Summary
This earthquake hit under water in the South Pacific Ocean, 186 kilometers (116 mi) off the coast of Fiji, 273 kilometer south-east of Labasa in Northern. The center of this earthquake had a very deep depth of 571 km. Deep earthquakes usually have less impact than shallower earthquakes of similar strenght.

Risk of aftershocks?
This earthquake did not have any significant foreshocks nor aftershocks occurring within 100km (62 mi) of its epicenter.
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.
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 are very common in the region. This is the strongest earthquake to hit since July 5th, 2026, when a 5.8 magnitude earthquake hit 236 km (147 mi) further south. An even stronger magnitude 8.2 earthquake struck on August 19th, 2018.
In total, 147 earthquakes with a magnitude of 5.1 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 25 days.
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 5.1. Earthquakes of this strength are unlikely to trigger a tsunami. |
Not this earthquake. This earthquake occurred at a depth of 571 km (355 mi). Earthquakes this deep in the earth are unlikely to trigger a tsunami. |
