Earthquakes in October 2025: 7,451 Recorded Worldwide

7,451 earthquakes were recorded worldwide in October 2025, an average of 240 per day.

That is down 11% on the 8,392 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 October 2025 was a magnitude 7.6 earthquake near Drake Passage on 10 October, at a focal depth of 10 km. A magnitude 7.6 earthquake radiates roughly 3.8 million tons of TNT equivalent in seismic energy.

By band, October 2025 produced 6 in the magnitude -2 range, 274 in the magnitude -1 range, 1655 in the magnitude 0 range, 3545 in the magnitude 1 range, 1049 in the magnitude 2 range, 208 in the magnitude 3 range.

93% 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 07 October 2025, with 337 recorded events.
