M6.4 Earthquake near Banda Sea — October 28, 2025
2025-10-28 14:40:18 UTC (2025-10-28) · approx. 11:40 PM UTC+9 local
Felt by 17 people across nearby locations. Maximum shaking intensity MMI 4.3 (moderate).
On October 28, 2025 at 14:40 UTC, a magnitude 6.4 intermediate depth earthquake struck near Banda Sea, at a depth of 142.0 km and coordinates -6.7001°, 129.9887°. The earthquake was reported felt by 17 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.3 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 263 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 635, making it a moderate-impact event.
Physical scale: An earthquake of magnitude 6.4 releases seismic energy equivalent to roughly 60 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 16 km — a useful intuition for the size of the slip patch on the fault.
