abstract: An important characteristic of seismicity is the distribution
and magnitude of earthquakes. Fluid injection in rocks,
aimed to create enhanced geothermal systems (EGS), can
sometimes produce significant seismic events (e.g., Majer et
al., 2007). This is rarely the case in hydraulic fracturing of
hydrocarbon reservoirs. However, in any case the behavior of
the seismicity triggering in space and in time is controlled by
the process of stress relaxation and pore-pressure perturbation
that was initially created at the injection source. This relaxation
process can be approximated by pressure diffusion (possibly
a nonlinear one) in the pore fluid of rocks (e.g., Shapiro and
Dinske, 2009). At some locations the tectonic stress in the
Earth’s crust is close to a critical stress, causing brittle failure
of rocks. Increasing fluid pressure in such a reservoir causes
pressure in the connected pore and fracture space of rocks to
increase. Such an increase in the pore pressure consequently
causes a decrease of the effective normal stress. This leads
to sliding along pre-existing, favorably oriented, subcritical
cracks.
