Felt by 21 people across nearby locations.
On March 27, 2023 at 18:20 UTC, a magnitude 4.7 shallow crustal earthquake struck in the Lake Edward region, Congo-Uganda, at a depth of 14.8 km and coordinates -0.6618°, 29.3042°. This earthquake was detected by 45 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 349, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
