On August 9, 2024 at 08:22 UTC, a magnitude 4.9 shallow crustal earthquake struck near central East Pacific Rise, at a depth of 10.0 km and coordinates -4.7382°, -105.2137°.0 This earthquake was detected by 52 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
