On August 7, 2020 at 06:15 UTC, a magnitude 5.0 shallow crustal earthquake struck 3 km NNE of Sidi Mérouane, Algeria, at a depth of 10.0 km and coordinates 36.5497°, 6.2708°. The earthquake was reported felt by 19 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.5 (very strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is Sidi Merouane (population 25,129).

Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
