2023-01-18 22:01:27 UTC (2023-01-18) · approx. 7:01 AM UTC+9 local
On January 18, 2023 at 22:01 UTC, a magnitude 4.4 shallow crustal earthquake struck 60 km W of Manokwari, Indonesia, at a depth of 35.3 km and coordinates -0.8570°, 133.5224°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
