Earthquakes in Fiji — June 2025

12 earthquakes were recorded in Fiji during June 2025, an average of 0.4 per day.

12 reached magnitude 4 or above and 1 reached magnitude 5 or above. The average focal depth was 586 km.

The month's largest event in Fiji was a magnitude 5.2 earthquake near Fiji region on 18 June 2025 at 12:08 UTC. A magnitude 5.2 earthquake radiates roughly 951 tons of TNT equivalent in seismic energy.

That is close to the Fiji monthly average of 15 events over the period we cover, and up from the 7 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 11 in the magnitude 4 range, 1 in the magnitude 5 range.

Activity peaked on 10 June, when 2 events were recorded.

The month's largest events were M5.2 near Fiji region on 18 June at 620 km; M4.9 near Levuka, Fiji on 24 June at 560 km; M4.7 near Fiji region on 10 June at 550 km.

That is 17% below the 15 events Fiji averages per month across the 21 months on record.
