| Zusammenfassung |
| The standard paradigm to describe seismicity induced by fluid
injection is to apply nonlinear diffusion dynamics in a poroelastic
medium. I show that the spatiotemporal behaviour and rate evolution
of induced seismicity can, instead, be expressed by geometric
operations on a static stress field produced by volume change at
depth. I obtain laws similar in form to the ones derived from
poroelasticity while requiring a lower description length. Although
fluid flow is known to occur in the ground, it is not pertinent to
the behaviour of induced seismicity. The proposed model is
equivalent to the static stress model for tectonic foreshocks
generated by the Non-Critical Precursory Accelerating Seismicity
Theory. This study hence verifies the explanatory power of this
theory outside of its original scope. |
