On December 12, 2022 at 18:37 UTC, a magnitude 4.8 deep-focus earthquake struck 176 km NNW of Maubara, Timor Leste, at a depth of 543.5 km and coordinates -7.0751°, 124.7900°. This earthquake was detected by 107 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
