Earthquakes in March 2025: 8,258 Recorded Worldwide

8,258 earthquakes were recorded worldwide in March 2025, an average of 266 per day.

That is essentially level with the 8,435 recorded in the preceding period — global seismicity is remarkably steady from one month to the next.

The largest event of March 2025 was a magnitude 7.7 earthquake near Sagaing, Myanmar on 28 March, at a focal depth of 10 km. A magnitude 7.7 earthquake radiates roughly 5.4 million tons of TNT equivalent in seismic energy.

By band, March 2025 produced 13 in the magnitude -2 range, 462 in the magnitude -1 range, 2188 in the magnitude 0 range, 3500 in the magnitude 1 range, 1138 in the magnitude 2 range, 273 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 20 March 2025, with 364 recorded events.

Most active: the United States (7185), Puerto Rico (337), Indonesia (93), Chile (45), Japan (40).
