Summary:The methodology and results of these determination of the stress deviator from striated faults or of focal mechanisms of earthquakes in S Tibet and the Cuzco region of the High Andes are presented, with a discussion of the spatial and temporal changes in the tectonic regimes of these regions. The Quaternary-Present stress patterns favour models explaining the spatial changes in the state of stress at a long wavelength due to compensated high relief. Major temporal changes in the tectonic regimes are attributed to uplift of the Tibetan Plateau, and to changes in the size of boundary forces due to subduction in the already elevated Andean Plateau.
