Earthquakes in the Solomon Islands — September 2026
1 earthquakes were recorded in the Solomon Islands during September 2026, an average of 0.0 per day.
1 reached magnitude 4 or above and 1 reached magnitude 5 or above. The average focal depth was 39 km.
The month's largest event in the Solomon Islands was a magnitude 5.6 earthquake near Kirakira, Solomon Islands on 06 September 2026 at 04:05 UTC. A magnitude 5.6 earthquake radiates roughly 3,788 tons of TNT equivalent in seismic energy.
That is below the the Solomon Islands monthly average of 6 events over the period we cover — a comparatively quiet month, and down from the 8 recorded the previous month.
100% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 0% deep-focus (over 300 km). Almost everything here is crustal. That is characteristic of transform faulting or continental deformation rather than subduction — and it means shaking at the surface is strong for the magnitudes involved.
By band, the catalogue holds 1 in the magnitude 5 range.
That is 83% below the 6 events the Solomon Islands averages per month across the 22 months on record.
