A minor magnitude 3.6 earthquake struck 141 km NNW of Charlotte Amalie, Mali on Sunday, September 13, 2026 at 03:23:40 AM UTC. This shallow crustal event (13.0 km depth) released energy equivalent to approximately 4 tons of TNT. Here is the verified PR telemetry, live epicenter map, and ground shaking assessment.

A magnitude 3.6 event is classified as a minor earthquake. Often felt by people indoors, especially on upper floors. Hanging objects may swing slightly; structural damage is extremely rare.
Felt by almost no one except under extraordinarily favorable conditions.

Mali's seismicity is fundamentally governed by its tectonic setting: Occupies the central part of the ancient West African Craton and the vast, stable Taoudeni sedimentary basin.. Major regional fault structures include Adrar des Ifoghas Fault System, Gourma Fold Belt Lineament.
Originating at a depth of 13.0 km (Earth's Crust (0–70 km)), this rupture occurred occurred within the brittle upper crust. shallow earthquakes produce the highest peak ground acceleration and the sharpest surface shaking.
Seismologists note that minor aftershocks remain common in the 24 to 48 hours following tremors of magnitude 3.6. According to statistical seismic models, there is roughly a 5% probability of a subsequent event of equal or greater strength occurring in the same fault zone. Residents in Mali are advised to check living spaces for unsecured items.
