- Аннотация: This chapter will present the results of reconstruction of modern state of stress, obtained by the method of cataclastic analysis of discontinuous displacements (MCA), for three seismically active regions of Asia: the Northern Tien Shan, the Altai-Sayan region and the Kuril-Kamchatka region. The stress data on the earthquake focal mechanisms are taken from global and regional seismic catalogues. The Northern Tien Shan and the Altai-Sayan region are the intracontinental orogenes. The Kuril Islands and Kamchatka are active continental margins. The similarities and differences in the state of stress between these two geodynamic types of deformation of the lithosphere are shown in this chapter. The goal of this chapter is to show the capabilities of the MCA. In contrast to other methods of reconstruction of the tectonic stress, the MCA allow one to obtain data not only on the parameters of stress ellipsoid, but also on the stress values. Various ways of visualizing parameters reflecting the spatial variations of tensor components will be presented in this chapter. Again, it should be noted that the longitudinal stress is positive under tension and negative under compression. This positive-negative sign convention is accepted in classical mechanics. This is the opposite of the criterion used in mining.
