The article is devoted to a strong earthquake that occurred on June 28, 2025 in the north-east of Yakutia, the southern Dmitry Laptev Strait. This event was called the South Anyui earthquake, since it is associated with tectonic manifestations of the South Anyui suture zone. The earthquake source was located at a depth of 10 kilometers, its magnitude was 5.3, with coordinates 72.33°N, 142.14°E. The earthquake parameters were determined using the "Unique Scientific Installation" [Dyagilev, Sdelnikova, 2022]. The epicenter of the earthquake was located on the territory of the Ust-Yansky district, the Republic of Sakha (Yakutia), the Russian Federation. The intensity at the epicenter, according to instrumental data from the GS RAS (http://www.gsras.ru), reached 6–7 points on the MSK-64 scale. The features of the Tastakh trough and the associated magnetic anomaly in the South Anyui suture zone are considered.
