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.

SCEC Meeting Times
We recognize that the CME meeting times overlap with related SCEC workshops listed here: [1]. Several CME group members want to participate in both meetings. To support these collaborative meetings, we will keep the CME meeting informal so that CME participants can move freely moving between meetings. We will try to keep the CME meeting on schedule so that you can determine when specific topics will be discussed at the CME meeting.
