Estimating the stress and strain fields of the Earth's crust on the basis of seismotectonic data

A method is proposed for estimating the lateral pressure coefficients q(x), q(y) on the basis of seismological data (the principal stress or principal strain trajectories). Results obtained by this method for the iron-ore dep osits of Gornaya Shoriya are in good correlation with in-situ data. For the main tectonic regimes (normal faults, strike-slip faults, thrust faults), the range of q(x), q(y) variation is established, and the conditions for th e application of two-dimensional models and relation for which motion along fracture disturbances is possible are determined.
