M4.6 Earthquake in the Azores Islands region — November 14, 2024
2024-11-14 00:44:39 UTC (2024-11-14) · approx. 10:44 PM UTC-2 local
On November 14, 2024 at 00:44 UTC, a magnitude 4.6 shallow crustal earthquake struck in the Azores Islands region, at a depth of 10.0 km and coordinates 36.3385°, -33.7911°. This earthquake was detected by 51 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
