M4.5 Earthquake near east central Pacific Ocean — April 8, 2024
2024-04-08 17:42:02 UTC (2024-04-08) · approx. 10:42 AM UTC-7 local
On April 8, 2024 at 17:42 UTC, a magnitude 4.5 shallow crustal earthquake struck near east central Pacific Ocean, at a depth of 10.0 km and coordinates -5.4914°, -111.9648°. This earthquake was detected by 70 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
