M6.1 Earthquake near Banda Sea — November 10, 2023
2023-11-10 20:45:11 UTC (2023-11-10) · approx. 5:45 AM UTC+9 local
Maximum shaking intensity MMI 5.2 (strong).
On November 10, 2023 at 20:45 UTC, a magnitude 6.1 shallow crustal earthquake struck near Banda Sea, at a depth of 10.0 km and coordinates -6.0976°, 130.0606°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 186 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 572, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 6.1 releases seismic energy equivalent to roughly 21 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 9.7 km — a useful intuition for the size of the slip patch on the fault.
