Earthquakes in the Northern Mariana Islands

Seismic activity in the Northern Mariana Islands is moderate by global standards, with 5 events recorded in the past 30 days, and 14 of the events on record reached magnitude 5 or above — the level at which damage becomes a genuine concern for vulnerable construction.

67 earthquakes have been recorded in the Northern Mariana Islands in our catalogue, 5 of them in the past 30 days.

The average magnitude is 4.8 and the average focal depth 180 km. 67 events reached magnitude 4 or above and 14 reached magnitude 5 or above.

The strongest earthquake recorded in the Northern Mariana Islands in this period was a magnitude 5.8 event near San Jose Village, Northern Mariana Islands on 15 December 2025, at a depth of 126 km. A magnitude 5.8 earthquake radiates roughly 7,558 tons of TNT equivalent in seismic energy.

Locations recording the most events include Saipan (19), San Jose Village (8).

24% of events here are shallow (under 70 km), 60% intermediate (70–300 km) and 16% deep-focus (over 300 km). That proportion of deep-focus events is the signature of a subduction zone: only a cold slab descending into the mantle stays brittle enough to rupture at those depths.

The deepest event on record here was a magnitude 4.3 earthquake at 607 km beneath Pagan region, Northern Mariana Islands on 27 December 2024.

By band, the catalogue holds 53 in the magnitude 4 range, 14 in the magnitude 5 range.

The busiest single day was 27 December 2024, with 2 recorded events.

No event in this record carries a USGS link to NOAA tsunami information.
