Earthquakes in the Solomon Islands

Seismic activity in the Solomon Islands is moderate by global standards, with 7 events recorded in the past 30 days, and 64 of the events on record reached magnitude 5 or above — the level at which damage becomes a genuine concern for vulnerable construction. The Solomon Islands sits on the Pacific Ring of Fire, and the depth distribution below shows the subducting slab beneath it directly.

135 earthquakes have been recorded in the Solomon Islands in our catalogue, 7 of them in the past 30 days.

The average magnitude is 5.0 and the average focal depth 53 km. 135 events reached magnitude 4 or above and 64 reached magnitude 5 or above.

The strongest earthquake recorded in the Solomon Islands in this period was a magnitude 6.7 event near Kirakira, Solomon Islands on 06 March 2026, at a depth of 10 km. A magnitude 6.7 earthquake radiates roughly 169,203 tons of TNT equivalent in seismic energy.

Locations recording the most events include Lata (51), Kirakira (43), Gizo (13), Malango (8), Honiara (7).

70% of events here are shallow (under 70 km), 30% intermediate (70–300 km) and 0% deep-focus (over 300 km). The mix is dominated by shallow crustal events, with a minority of intermediate-depth activity.

The deepest event on record here was a magnitude 4.6 earthquake at 209 km beneath Lata, Solomon Islands on 12 January 2025.

By band, the catalogue holds 71 in the magnitude 4 range, 58 in the magnitude 5 range, 6 in the magnitude 6 range.

The busiest single day was 20 December 2024, with 3 recorded events.

1 of these events carry a USGS link to NOAA tsunami information. That link flag does not mean a tsunami occurred or that a warning was issued.
