Earthquakes in August 2025: 8,539 Recorded Worldwide

8,539 earthquakes were recorded worldwide in August 2025, an average of 275 per day.

That is down 14% on the 9,913 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 August 2025 was a magnitude 8.0 earthquake near Drake Passage on 22 August, at a focal depth of 10 km. A magnitude 8.0 earthquake radiates roughly 15.1 million tons of TNT equivalent in seismic energy.

By band, August 2025 produced 11 in the magnitude -2 range, 420 in the magnitude -1 range, 2454 in the magnitude 0 range, 3554 in the magnitude 1 range, 915 in the magnitude 2 range, 225 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 01 August 2025, with 372 recorded events.

Most active: the United States (7334), Russia (457), Puerto Rico (185), Indonesia (63), Japan (41).
