Manifestations of Seismicity in the Low-Activity Territory of the Northeastern Caspian Region
The article examines manifestations of seismicity in the area of the junction of the Turan (Scythian) Plate and East European Platform in the historical and modern periods. Information for temporary and permanent seismic stations in this area and its vicinity is presented. The study area is characterized by the manifestation of both natural and anthropogenic seismicity initiated by the development of oil and gas fields. There is a natural earthquake zone associated with collapses in the salt layer of the Caspian Region, which includes earthquakes near Lake Shalkar in 1830, 1989, and 2008. The parameters of the strong earthquake of April 25, 2023, with mb = 4.5 in Mangistau oblast are presented, as well as the focal mechanisms of the strongest earthquakes in Western Kazakhstan.
