The hazard curve calculator computes hazard curves (probabilities of exceedence values for a set of ground motion intensities in a given time span) for a list of sites, taking as input a seismogenic source model and a set of GMPEs defining the ground motion model for each tectonic region type involved by the source model.

Notes

  • Assumptions

The calculator computes hazard curves following the approach of Field et al. 2003 (Field, E.H., T.H. Jordan, and C.A. Cornell (2003), OpenSHA: A Developing Community-Modeling Environment for Seismic Hazard Analysis, Seismological Research Letters, 74, no. 4, p. 406-419.).

  • Design

The seismogenic source model, together with the time span, is used to compute the corresponding Earthquake Rupture Forecast (ERF) (that is the list of all possible ruptures derived by the source model together with their probability of occurrence). The ERF is then used for the hazard curve calculation.

  • User stories:

  • Identify, isolate and group OpenSHA core functionalities for ERF creation

  • Identify, isolate and group OpenSHA core functionalities for classic PSHA calculation

  • Suggested Implementation
