“…With regard to this last study, it is important to note that the probabilistic hazard for Central Asia was estimated in terms of intensity and then converted to peak ground acceleration (PGA) by Ulomov (1999) using the Aptikaev and Shebalin (1988) relationship. During the 1990's, the seismic hazard in term of intensities was assessed for many capitals in Central Asia following a probabilistic approach and some results are summarized in Nurmagambetov et al (1999). As an example, the DSZ map in terms of both intensity and peak ground acceleration was constructed for the suburbs of Almaty (Kyurskeyev, 1993) and the probabilistic values of seismic hazard in Almaty were assessed in terms of peak accelerations and intensity following the Cornell (1968) approach (Mikhailova, 1996).…”

In the process of updating existing PSHA maps in Central Asia, a first step is the evaluation of the seismic hazard in terms of macroseismic intensity by applying a data driven method. Following the Site Approach to Seismic Hazard Assessment (SASHA) , the evaluation of the probability of exceedance of any given intensity value over a fixed exposure time, is mainly based on the seismic histories available at different locations without requiring any a-priori assumption about seismic zonation. The effects of earthquakes non included in the seismic history can be accounted by propagating the epicentral information through a Intensity Prediction Equation developed for the analyzed area. In order to comply with existing building codes in the region that use macroseismic intensity instead of PGA, we evaluated the seismic hazard at 2911 localities using a macroseismic catalogue composed by 5322 intensity data points relevant to 75 earthquakes in the magnitude range 4.6-8.3. The results show that for most of the investigated area the intensity having a probability of at least 10% to be exceeded in 50 years is VIII. The intensity rises to IX for some area struck by strong earthquakes in the past, like the Chou-Kemin-Chilik fault zone in northern Tien-Shan, between Kyrgyzstan and Kazakhstan, or in Gissar range between Tajikistan and Uzbekistan. These values are about one degree less than those evaluated in the Global Seismic Hazard Assessment Program (GSHAP;Ulomov, 1999). Moreover, hazard curves have been extracted for the main towns of Central Asia and the results compared with the estimates previously obtained. A good agreement has been found for Bishkek (Kyrgyzstan) and Dushanbe (Tajikistan), while a lower probability of occurrence of I=VIII has been obtained for Tashkent (Uzbekistan) and a larger one for I=IX in Almaty (Kazakhstan).2

“…These findings indicate the degree to which a high‐magnitude earthquake might devastate a large city like Almaty, which is constructed to the same building standards. A study conducted prior to the Lugovskoy earthquake concludes that approximately 70 per cent of multi‐storey residential buildings in urban areas had ‘not been designed to current seismic requirements’ (Nurmagembetov, Mikhailova, and Iwan, 1999, pp. 16, 25).…”

What happened to the Second World? Earthquakes and postsocialism in Kazakhstan

There is an assumption that with the disintegration of the Soviet Union, the Second World ceased to exist. Yet the demise of the Communist bloc as a geopolitical reality did not mean that it stopped exerting a defining influence over how people think and behave. This article examines how the postsocialist state in Kazakhstan deals with potential crises such as earthquakes and the extent to which the Soviet legacy still shapes intellectual debates, state structures, and civil society organisations in in that country. Drawing on fieldwork and interviews, this paper re-examines the Second World in its historical context and re-establishes it as a conceptual framework for considering disaster risk reduction in the former Soviet bloc. It argues that it is essential to pay attention to this legacy in Kazakhstan both in policy and practice if earthquake risk reduction is to be made more effective.

“…One example is the 1887 Verny (former name of Almaty, at that time the capital of Kazakhstan) earthquake, for which a detailed survey about the effects generated in the region was performed under the guidance of Mushketov. A detailed description of the damage in Almaty was also compiled, providing an overview of the spatial variability of damages within the town and relating the damage to the building characteristics (Nurmagambetov et al, 1999).…”

“…The differences among the three zoning levels are in the content, methods, and objectives of the investigation, leading to different scales of mapping (e.g., Nurmagambetov et al, 1999). In particular, the GSZ-97 was compiled in the 1990s (Ulomov and the GSHAP Region 7 Working Group, 1999) and included in the GSHAP project (Giardini, 1999;Zhang et al, 1999).…”
