2023-02-19 20:53:57 UTC (2023-02-19) · approx. 4:53 AM UTC+8 local
On February 19, 2023 at 20:53 UTC, a magnitude 4.2 shallow crustal earthquake struck 110 km ESE of Bitung, Indonesia, at a depth of 40.0 km and coordinates 0.9002°, 125.9601°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
