M4.3 Earthquake 5 km SSW of Bulnes, Chile — November 7, 2024
2024-11-07 22:10:50 UTC (2024-11-07) · approx. 5:10 PM UTC-5 local
On November 7, 2024 at 22:10 UTC, a magnitude 4.3 shallow crustal earthquake struck 5 km SSW of Bulnes, Chile, at a depth of 63.1 km and coordinates -36.7838°, -72.3298°. The nearest populated place is Bulnes (population 12,715).
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
