In connection with the reform of regulatory framework for construction sector of the Republic of Kazakhstan, the development of seismic zoning maps poses an urgent problem. The article presents a set of seismic microzoning maps of Almaty, developed on a new methodological basis for Kazakhstan, and provides explanatory materials on the development, understanding and use. Calculation of background seismic hazard was carried out in accordance with the basic provisions of Eurocode 8. Seismic microzoning included the implementation of two main tasks - the assessment of background seismicity and taking into account influence of soil conditions. Based on the analysis results, a set of maps have been arranged. When taking into account the influence of engineering and geological conditions, Russian and Kazakh works were used. The main maps ready for use in regulatory documents are provided. Analysis of capacities of the sediments of same age in different blocks made it possible to understand the dynamics of tectonic regime of the city territory. In the process of neotectonic activation, almost all previously existing tectonic disturbances were improved. In the contemporary relief of the urban area, most faults are not expressed.
