Earthquakes in Malta — September 2025
2 earthquakes were recorded in Malta during September 2025, an average of 0.1 per day.

The month's largest event in Malta was a magnitude 5.1 earthquake near Birżebbuġa, Malta on 15 September 2025 at 09:55 UTC. A magnitude 5.1 earthquake radiates roughly 674 tons of TNT equivalent in seismic energy.
That is well above the Malta monthly average of 2 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 5 range.
The month's largest events were M5.1 near Birżebbuġa, Malta on 15 September at 10 km; M4.5 near Birżebbuġa, Malta on 11 September at 10 km.
That is 33% above the 2 events Malta averages per month across the 2 months on record.
