In 2019, the Engineering and Seismometric Service Stations of Kazakh Scientific Research and Design Institute of Civil Engineering and Architecture JSC registered 3 Local Earthquakes with foci in Almaty city and adjacent areas of Almaty region. In September 2019, there were two earthquakes with foci near Almaty city. Earthquake accelerogram recorded in the substructure and upstairs of an 11-storey building with a steel frame, as well as on the 10th and 16th floors in a 17-storey building with a stiffening core were obtained on September 02, 2019, September 07, 2019. The buildings are located near tectonic faults. Spectral curves describing the frequency content of the seismic impact are constructed. It is established that the frequency behavior of the footing, composed of soils of the 2nd category in terms of seismic properties, are high-frequency with prevailing periods of 0.06–0.13 s. Resonance phenomena for flexible buildings were not observed in the local earthquakes indicated. Instrumental records are included in the database of accelerograms of Kazakh Scientific Research and Design Institute of Civil Engineering and Architecture JSC. The results of the work can be used in the calculation and design of buildings and structures in Almaty city. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.DOI
