The month's largest event in Indonesia was a magnitude 5.8 earthquake near Blangpidie, Indonesia on 31 January 2025 at 11:03 UTC. A magnitude 5.8 earthquake radiates roughly 7,558 tons of TNT equivalent in seismic energy.

That is below the Indonesia monthly average of 69 events over the period we cover — a comparatively quiet month, and down from the 78 recorded the previous month.

71% of events here are shallow (under 70 km), 27% intermediate (70–300 km) and 2% deep-focus (over 300 km). The mix is dominated by shallow crustal events, with a minority of intermediate-depth activity.

By band, the catalogue holds 40 in the magnitude 4 range, 9 in the magnitude 5 range.
