Shear tensile-implosion source model vs. moment tensor: benefit in single-azimuth monitoring, Cotton Valley set-up
Original language description
Moment tensor (MT) has become a standard for description of seismic sources, both in earthquake seismology and for various types of induced seismicity. It is a general dipole source, but for practice it may be too general, its generality causing troublesduring its reconstruction from noisy data in the inverse process, which may be additionally ill-conditioned due to inexact hypocenter location or availability of a rough velocity/attenuation model only. Then, the retrieved source may be biased. It seemsreasonable to assume a simpler source model directly describing the physical phenomena anticipated in the particular focus. A simple combination of a shear slip with tensile crack or 1D implosion (STI) may be a good model both for natural earthquakes and induced events. The model simplification introduced is crucial in cases of depleted sensor configuration when the moment tensor fails, in single-azimuth monitoring in particular. This is just the case of application in oil and gas indus
