Earthquakes in Fiji — January 2025

16 earthquakes were recorded in Fiji during January 2025, an average of 0.5 per day.

16 reached magnitude 4 or above and 1 reached magnitude 5 or above. The average focal depth was 557 km.

The month's largest event in Fiji was a magnitude 5.4 earthquake near Levuka, Fiji on 12 January 2025 at 15:03 UTC. A magnitude 5.4 earthquake radiates roughly 1,898 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 18 recorded the previous month.

0% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 100% 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 15 in the magnitude 4 range, 1 in the magnitude 5 range.

Activity peaked on 27 January, when 2 events were recorded.

The month's largest events were M5.4 near Levuka, Fiji on 12 January at 608 km; M4.9 near Fiji region on 07 January at 373 km; M4.8 near Fiji region on 05 January at 553 km.

That is 10% above the 15 events Fiji averages per month across the 21 months on record.
