2020-11-20 20:03:46 UTC (2020-11-20) · approx. 7:03 AM UTC+11 local
On November 20, 2020 at 20:03 UTC, a magnitude 5.1 shallow crustal earthquake struck near Santa Cruz Islands, at a depth of 10.0 km and coordinates -11.5043°, 167.3002°.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
