M4.9 Earthquake northwest of Australia — January 28, 2022
2022-01-28 11:20:37 UTC (2022-01-28) · approx. 7:20 PM UTC+8 local
On January 28, 2022 at 11:20 UTC, a magnitude 4.9 shallow crustal earthquake struck northwest of Australia, at a depth of 10.0 km and coordinates -12.0774°, 112.8834°.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
