Felt by 22 people across nearby locations.
On November 8, 2020 at 12:08 UTC, a magnitude 4.7 shallow crustal earthquake struck in the Prince Edward Islands region, at a depth of 10.0 km and coordinates -46.6586°, 42.3126°.
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.
