The month's largest event in Martinique was a magnitude 4.5 earthquake near Sainte-Marie, Martinique on 20 September 2026 at 02:44 UTC. A magnitude 4.5 earthquake radiates roughly 85 tons of TNT equivalent in seismic energy.
That is close to the Martinique monthly average of 1 events over the period we cover.
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.
That is 20% below the 1 events Martinique averages per month across the 4 months on record.
