On August 2, 2023 at 03:36 UTC, a magnitude 4.8 shallow crustal earthquake struck 33 km ENE of Dek’emhāre, Eritrea, at a depth of 10.0 km and coordinates 15.1591°, 39.3496°. This earthquake was detected by 73 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
