Earthquakes in Fiji — March 2026

13 earthquakes were recorded in Fiji during March 2026, an average of 0.4 per day.

13 reached magnitude 4 or above and 1 reached magnitude 5 or above. The average focal depth was 581 km.

The month's largest event in Fiji was a magnitude 6.3 earthquake near Fiji region on 01 March 2026 at 05:44 UTC. A magnitude 6.3 earthquake radiates roughly 42,502 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 19 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 12 in the magnitude 4 range, 1 in the magnitude 6 range.

Activity peaked on 17 March, when 2 events were recorded.

The month's largest events were M6.3 near Fiji region on 01 March at 596 km; M4.9 near Fiji region on 20 March at 593 km; M4.9 near Fiji region on 21 March at 503 km.

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

This month also holds the strongest earthquake recorded in Fiji in our entire catalogue.
