On the realization of seismic microzonation of Almaty (Kazakhstan) in ground accelerations based on the “continual” approach
Seismic microzonation for Almaty city for the first time use probabilistic approach and hazard is expressed in terms of not only macroseismic intensity, but also Peak Ground Acceleration (PGA). To account for the effects of local soil conditions, the continual approach proposed by A.S. Aleshin [1, 2...

| description | Seismic microzonation for Almaty city for the first time use probabilistic approach and hazard is expressed in terms of not only macroseismic intensity, but also Peak Ground Acceleration (PGA). To account for the effects of local soil conditions, the continual approach proposed by A.S. Aleshin [1, 2] was used, in which soil coefficients are a function of the continuously changing seismic rigidity. Soil coefficients were calculated using the new data of geological and geophysical surveys and findings of previous geotechnical studies. The used approach made it possible to avoid using soil categories and a jump change in characteristics of soil conditions and seismic impact. The developed seismic microzonation maps are prepared for further introduction into the normative documents of the Republic of Kazakhstan. Keywords: Seismic microzonation maps, Peak ground acceleration, Soil conditions, Seismic rigidity, Continual theory |
