Earthquakes in the Solomon Islands — March 2025

7 earthquakes were recorded in the Solomon Islands during March 2025, an average of 0.2 per day.

7 reached magnitude 4 or above and 3 reached magnitude 5 or above. The average focal depth was 25 km.

The month's largest event in the Solomon Islands was a magnitude 5.3 earthquake near Honiara, Solomon Islands on 04 March 2025 at 07:07 UTC. A magnitude 5.3 earthquake radiates roughly 1,344 tons of TNT equivalent in seismic energy.

That is close to the the Solomon Islands monthly average of 6 events over the period we cover, and level with the 7 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 4 in the magnitude 4 range, 3 in the magnitude 5 range.

Activity peaked on 27 March, when 2 events were recorded.

The month's largest events were M5.3 near Honiara, Solomon Islands on 04 March at 10 km; M5.0 near Honiara, Solomon Islands on 26 March at 10 km; M5.0 near Buala, Solomon Islands on 21 March at 10 km.

That is 12% above the 6 events the Solomon Islands averages per month across the 21 months on record.
