The month's largest event in El Salvador was a magnitude 4.3 earthquake near Acajutla, El Salvador on 06 September 2026 at 04:00 UTC. A magnitude 4.3 earthquake radiates roughly 43 tons of TNT equivalent in seismic energy.
That is below the El Salvador monthly average of 4 events over the period we cover — a comparatively quiet month, and level with the 2 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 2 in the magnitude 4 range.
The month's largest events were M4.3 near Acajutla, El Salvador on 06 September at 10 km; M4.2 near Acajutla, El Salvador on 04 September at 42 km.
