SCEC/CME Meeting Agenda Sept 11, 2011

Fig 2: SCEC Broadband CyberShake PSHA hazard calculations produces PSHA hazard curves at frequencies up to 10Hz, by combining 0.5Hz deterministic waveform-based CyberShake hazard curves, based on UCERF2.0, with stochastic high frequencies from the SCEC Broadband Platform v11.2.0. The resulting PSHA hazard curves provide estimates at frequencies needed to validate PSHA hazard curves for specific precarious 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.
