Earthquakes in El Salvador — August 2025

The month's largest event in El Salvador was a magnitude 6.0 earthquake near Acajutla, El Salvador on 23 August 2025 at 09:14 UTC. A magnitude 6.0 earthquake radiates roughly 15,080 tons of TNT equivalent in seismic energy.
That is close to the El Salvador monthly average of 4 events over the period we cover, and down from the 5 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 3 in the magnitude 4 range, 1 in the magnitude 6 range.
The month's largest events were M6.0 near Acajutla, El Salvador on 23 August at 10 km; M4.2 near Puerto El Triunfo, El Salvador on 04 August at 67 km; M4.2 near Acajutla, El Salvador on 18 August at 35 km.
That is close to the 4 events El Salvador averages per month across the 21 months on record.
