Description
| - Mechanismus mikrozemětřesení pozorovaných při indukované seismicitě (vztahující se k důlní činnosti, hydrofrakčním experimentům v průmyslu atd.) může obsahovat – mimo tradiční střižný skluz – také nestřižné složky momentového tenzoru. jejich rozlišení však může být obtížné vzhledem k chybám lokalizace hypocentra a modelování rychlostní struktury – efektům, které samy generují falešné nestřižné složky. Simulujeme střižně-tahový zdroj (vektor skluzu mimo rovinu zlomu) v konfiguraci seismického monitorování geotermálního zařízení Soultz a zkoumáme rozlišení tahové složky při různém stupni mislokace ohniska a chybném modelování rychlostní struktury. Kromě toho vyšetřujeme také vliv kvality pokrytí fokální sféry seismickými stanicemi a efekt absence S vln v datech. (cs)
- Mechanism of microearthquakes observed in induced seismicity (related to mining, hydrofracture experiments in industry etc.) may contain - in addition to the traditional shear slip - also non-double-couple components in the moment tensor. Their resolution can, however, be difficult, taking into account errors in location of the hypocenter and modeling the velocity structure – effects which themselves generate spurious non-double-couple components. We simulate a shear-tensile source (slip vector off the fault plane) in the configuration of the seismic monitoring in the Soultz geothermal facility and explore resolution of the tensile component when various types of hypocenter mislocation and/or mismodeling the velocity structure take place. Effects of deteriorating the quality of the focal sphere coverage by seismic stations as well as the absence of S data are also investigated.
