Stability of source mechanisms inverted from P-wave amplitude microseismic monitoring data acquired at the surface

Popis výsledku v původním jazyce

We study the stability of source mechanisms inverted from data acquired at surface and near-surface monitoring arrays. The study is focused on P-wave data acquired on vertical components, as this is the most common type of acquisition. We apply ray modelling on three models: a fully homogeneous isotropic model, a laterally homogeneous isotropic model and a laterally homogeneous anisotropic model to simulate three commonly used models in inversion. We use geometries of real arrays, one consisting in surface receivers and one consisting in buried? geophones at the near-surface. Stability was tested for two of the frequently observed source mechanisms: strike-slip and dip-slip and was evaluated by comparing the parameters of correct and inverted mechanisms. We assume these double-couple source mechanisms and use quantitatively the inversion allowing non-double-couple components to measure stability of the inversion. To test the robustness we inverted synthetic amplitudes computed for a la
