2023 PEER - LBNL Workshop

The Pacific Earthquake Engineering Research Center (PEER) and the Lawrence Berkeley National Laboratory (LBNL) are collaborating on the development of the first regional-scale, open-access simulated earthquake ground motion database for the San Francisco Bay Area.

This community workshop will discuss technical aspects of regional scale simulations and the implementation of the database on January 18-19, 2024 on the UC Berkeley campus.

The workshop will include presentations and discussion with technical experts and information on the planned database to inform both the research and infrastructure stakeholder communities.
