Workshop #1
This series of workshops focuses on developing international guidelines and standards for (1) archiving and disseminating, and (2) validating simulated earthquake ground-motion data. These workshops are open to anyone interested in these topics.
Workshop #1 will be a mixture of presentations and directed discussions to:
Summarize examples of simulated ground-motion data sets;
Assess the needs of users of simulated ground-motion data in terms of mechanisms for searching and accessing data, and what metadata is needed to describe the simulated data;
Assess what existing strong-motion data center standards and tools might be useful for simulated ground-motion data; and
Outline steps for developing international guidelines and standards for archiving and disseminating simulated ground-motion data.

Workshop #2
This series of workshops focuses on developing international guidelines and standards for (1) archiving and disseminating, and (2) validating simulated earthquake ground-motion data. These workshops are open to anyone interested in these topics. Workshop #2 will be a mixture of presentations and directed discussions to:
● Review the state of the art in validation of simulated motions for engineering applications.
● Summarize lessons learned during past validation efforts.
● Discuss experiences from different regions throughout the world.
● Discuss how to build on existing validation efforts, develop international guidelines for validating simulated motions for engineering applications, and convey validation status of datasets using appropriate metadata.
