M5.5 Earthquake 116 km WSW of Edd, Eritrea — November 23, 2025
2025-11-23 12:21:17 UTC (2025-11-23) · approx. 3:21 PM UTC+3 local
Felt by 1 person across nearby locations. Maximum shaking intensity MMI 7.2 (severe).
On November 23, 2025 at 12:21 UTC, a magnitude 5.5 shallow crustal earthquake struck 116 km WSW of Edd, Eritrea, at a depth of 3.0 km and coordinates 13.5880°, 40.6720°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 7.2 (severe). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected.0 The nearest populated place is Edd (population 11,259).
Physical scale: An earthquake of magnitude 5.5 releases seismic energy equivalent to roughly 3 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.8 km — a useful intuition for the size of the slip patch on the fault.
