Název v původním jazyce

Earthquake mechanisms and stress field

Popis výsledku v původním jazyce

The stress field and fracture processes in the Earth's crust are closely related phenomena. Fracturing is controlled by shear stress on the fault, pore-fluid pressure, cohesion and fault friction. In addition, the orientation of the fault with respect tothe principal stress directions governs susceptibility of the fault to be ruptured. An essential role play faults optimally oriented for shear faulting being the most unstable under the given stress. The type of faulting, the orientation of the faults and the direction of the slip along the faults can be inverted for stress and its spatial and temporal variations within the Earth's crust. The stress inversions work best if the fault orientations are known and the fault plane is uniquely identified fromthe focal mechanisms. The inversions retrieve the principal stress directions and the shape ratio. The accuracy of the results depends on the inversion method, the number of inverted focal mechanisms, their errors and variety.
