- Abstract
- In this report an update of the Probabilistic Seismic Hazard Assessment (PSHA) for induced seismicity in Groningen is presented. The original map, see Appendix A.1, has been published in a slightly different form in Dost et al. 2013) and was published in the context of the NPR-9998:2015v1.1(“Netherlands Guideline for the assessment of buildings in case of erection, reconstruction and disapproval - Basic rules for seismic actions; Induced earthquakes”). the map shows the probabilities of exceedance of ground motions in the area for a return period of 475 years. The hazard analysis was carried out using a probabilistic method, developed by Cornell (1968). Usually this method is applied to natural events of magnitudes (M>4) under assumption of a stationary process. For shallow induced events, magnitudes of damaging events are in general smaller and the process non-stationary and this requires an adaptation of the method (e.g. Eck et al., 2006; Kraaijpoel et al., 2014). A PSHA analysis consists of different components. Most important area spatial and statistical description of the seismicity in the area and a Ground Motion Prediction model, relating event magnitudes to peak ground acceleration (PGA) at the surface.
