2026-08-21 11:55:28 UTC (1 hour ago) · approx. 8:55 PM UTC+9 local
On August 21, 2026 at 11:55 UTC, a magnitude 4.6 intermediate depth earthquake struck near Banda Sea, at a depth of 169.6 km and coordinates -6.4826°, 129.8904°. This earthquake was detected by 27 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
