M4.0 Earthquake in the Peru-Ecuador border region — January 16, 2023
2023-01-16 21:04:16 UTC (2023-01-16) · approx. 4:04 PM UTC-5 local
On January 16, 2023 at 21:04 UTC, a magnitude 4.0 intermediate depth earthquake struck in the Peru-Ecuador border region, at a depth of 152.8 km and coordinates -2.1417°, -77.7717°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
