On June 27, 2021 at 09:50 UTC, a magnitude 4.7 shallow crustal earthquake struck in the Line Islands, Kiribati region, at a depth of 10.0 km and coordinates -3.2876°, -154.8138°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
