The month's largest event in El Salvador was a magnitude 4.2 earthquake near Acajutla, El Salvador on 04 September 2026 at 21:10 UTC. A magnitude 4.2 earthquake radiates roughly 30 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 down from 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 1 in the magnitude 4 range.
That is 72% below the 4 events El Salvador averages per month across the 22 months on record.
