Earthquakes in Samoa — March 2026
2 earthquakes were recorded in Samoa during March 2026, an average of 0.1 per day.
2 reached magnitude 4 or above and 1 reached magnitude 5 or above. The average focal depth was 10 km.
The month's largest event in Samoa was a magnitude 6.2 earthquake near Lotofagā, Samoa on 22 March 2026 at 15:27 UTC. A magnitude 6.2 earthquake radiates roughly 30,089 tons of TNT equivalent in seismic energy.
That is well above the Samoa monthly average of 1 events over the period we cover — an unusually active month, and up from the 1 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 4 range, 1 in the magnitude 6 range.
Activity peaked on 22 March, when 2 events were recorded.
The month's largest events were M6.2 near Lotofagā, Samoa on 22 March at 10 km; M4.8 near Gataivai, Samoa on 22 March at 10 km.
That is 60% above the 1 events Samoa averages per month across the 4 months on record.
This month also holds the strongest earthquake recorded in Samoa in our entire catalogue.
