Earthquakes in September 2026: 3 Recorded Worldwide
3 earthquakes were recorded worldwide in September 2026, an average of 0 per day.
That is down 100% on the 8,666 recorded in the preceding period. Short-term swings almost always reflect an aftershock sequence following one larger event rather than any global change.
The largest event of September 2026 was a magnitude 1.9 earthquake near McCloud, United States on 01 September, at a focal depth of 2 km. A magnitude 1.9 earthquake radiates roughly 13 kg of TNT equivalent in seismic energy.
By band, September 2026 produced 1 in the magnitude 0 range, 2 in the magnitude 1 range.
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.
The busiest single day was 01 September 2026, with 3 recorded events.
Most active: the United States (3).
