Abstract
A key element of quantifying both the hazard and risk due to induced
earthquakes is a suite of appropriate ground-motion prediction equations (GMPEs) that
encompass the possible shaking levels due to such events. Induced earthquakes are
likely to be of smaller magnitude and shallower focal depth than the tectonic earthquakes
for which most GMPEs are derived. Furthermore, whereas GMPEs for
moderate-to-large magnitude earthquakes are usually derived to be transportable to
different locations and applications, taking advantage of the limited regional dependence
observed for such events, the characteristics of induced earthquakes warrant the
development of application-specific models. A preliminary ground-motion model for
induced seismicity in the Groningen gas field in The Netherlands is presented as an
illustration of a possible approach to the development of these equations. The GMPE is
calibrated to local recordings of small-magnitude events and captures the epistemic
uncertainty in the extrapolation to larger magnitude considered in the assessment of
the resulting hazard and risk.
