Earthquakes in September 2026: 8,079 Recorded Worldwide

8,079 earthquakes were recorded worldwide in September 2026, an average of 269 per day.

That is down 7% on the 8,682 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 7.0 earthquake near Tadine, New Caledonia on 25 September, at a focal depth of 17 km. A magnitude 7.0 earthquake radiates roughly 476,879 tons of TNT equivalent in seismic energy.

By band, September 2026 produced 11 in the magnitude -2 range, 216 in the magnitude -1 range, 1871 in the magnitude 0 range, 3517 in the magnitude 1 range, 1382 in the magnitude 2 range, 397 in the magnitude 3 range.

92% of events here are shallow (under 70 km), 7% intermediate (70–300 km) and 1% 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 03 September 2026, with 398 recorded events.

Most active: the United States (7106), Puerto Rico (273), Indonesia (73), Mexico (50), Japan (48).
