Static behaviour of induced seismicity

摘要: Abstract. The standard paradigm to describe seismicity induced by fluid injection is apply non-linear diffusion dynamics in a poroelastic medium. I show that the spatio-temporal behaviour and rate evolution of can, instead, be expressed geometric operations on static stress field produced volume change at depth. obtain laws similar form ones derived from poroelasticity while requiring lower description length. Although flow known occur ground, it not pertinent geometrical patterns seismicity. proposed model equivalent for tectonic foreshocks generated Non-Critical Precursory Accelerating Seismicity Theory. This study hence verifies explanatory power this theory outside its original scope provides an alternative physical approach modelling applicability illustrated case 2006, Basel enhanced geothermal system stimulation experiment. Applicability more problematic cases where may spatially heterogeneous also discussed.
