SCEC/CME Meeting Agenda Sept 11, 2011

Fig 2: SCEC Broadband CyberShake PSHA hazard calculations produce PSHA hazard curves at frequencies up to 10Hz by combining 0.5Hz deterministic waveform-based UCERF2.0 hazard curves with stochastic high frequencies from the SCEC Broadband Platform v11.2.0. The resulting PSHA hazard curves provide peak ground motion estimates at frequencies and time-scales needed to validate PSHA hazard curves using precariously balanced rocks and other fragile geological structures.
