Developing International Standards and Guidelines for Curating, Validating and Disseminating Simulated Ground-motion Data
Description:
We are leading a working group within the Consortium of Organizations for Strong Motion Observation Systems (COSMOS) to develop international standards and guidelines for curating, validating, and disseminating simulated ground motion data for engineering applications. The scope encompasses all methods for generating simulated ground motions, including stochastic, three-dimensional wave propagation, and machine learning methods. We envision connecting geographically distributed data archives with a unified catalog to provide users with improved access to the simulated data through a standard interface.
Over the past three years, we have been building a worldwide community interested in producing or using simulated ground motion for engineering applications through special sessions, workshops, and presentations at various scientific and engineering meetings. Our current focus centers on forming three technical activity groups: (1) archiving and disseminating simulated ground motions, (2) validating simulated ground motions, and (3) utilizing simulated ground motions for engineering applications. The three groups will collaborate over the next one to two years to develop the international guidelines and standards. We expect the initial work will target a small set of representative vetted datasets to define standard metadata, validation metrics, and interfaces for searching and accessing the data. We want to link the application-specific validation metrics based on engineering design parameters, such as interstory drift, to features of the ground motions to make it easier for producers of simulated ground motions to improve their methodologies. Subsequent work will likely incorporate additional datasets and expand the metrics to accommodate additional engineering use cases.
