Earthquakes in Fiji — February 2025

14 earthquakes were recorded in Fiji during February 2025, an average of 0.5 per day.

14 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 529 km.

The month's largest event in Fiji was a magnitude 4.9 earthquake near Labasa, Fiji on 07 February 2025 at 07:03 UTC. A magnitude 4.9 earthquake radiates roughly 338 tons of TNT equivalent in seismic energy.

That is close to the Fiji monthly average of 15 events over the period we cover, and down from the 16 recorded the previous month.

7% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 93% deep-focus (over 300 km). That proportion of deep-focus events is the signature of a subduction zone: only a cold slab descending into the mantle stays brittle enough to rupture at those depths.

By band, the catalogue holds 14 in the magnitude 4 range.

Activity peaked on 16 February, when 4 events were recorded.

The month's largest events were M4.9 near Labasa, Fiji on 07 February at 10 km; M4.8 near Levuka, Fiji on 12 February at 613 km; M4.8 near Fiji region on 20 February at 547 km.

That is close to the 15 events Fiji averages per month across the 21 months on record.
