Earthquakes in Fiji — Page 4

Seismic activity in Fiji is moderate by global standards, with 12 events recorded in the past 30 days, and 33 of the events on record reached magnitude 5 or above — the level at which damage becomes a genuine concern for vulnerable construction. Fiji sits on the Pacific Ring of Fire, and the depth distribution below shows the subducting slab beneath it directly.

314 earthquakes have been recorded in Fiji in our catalogue, 12 of them in the past 30 days.

The average magnitude is 4.6 and the average focal depth 557 km. 314 events reached magnitude 4 or above and 33 reached magnitude 5 or above.

The strongest earthquake recorded in Fiji in this period was a magnitude 6.3 event near Fiji region on 01 March 2026, at a depth of 596 km. A magnitude 6.3 earthquake radiates roughly 42,502 tons of TNT equivalent in seismic energy.

Locations recording the most events include Levuka (148), Labasa (5), Lautoka (2), Suva (1), Nasinu (1).

2% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 98% 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.

The deepest event on record here was a magnitude 4.0 earthquake at 698 km beneath Fiji region on 30 March 2026.

By band, the catalogue holds 281 in the magnitude 4 range, 31 in the magnitude 5 range, 2 in the magnitude 6 range.

The busiest single day was 16 February 2025, with 4 recorded events.

No event in this record carries a USGS link to NOAA tsunami information.
