The National Academies convened a 1.5-day workshop to discuss management models of theoretical seismological and geodetic facilities of the future. Initial discussions built upon a 2015 Incorporated Research Institutions for Seismology community workshop report, which identified current and future capabilities of these research facilities. Management models from other types of scientific facilities were used as a springboard for further discussions about management and decision-making models that could be applied to seismological and geodetic facilities. Workshop participants also emphasized the importance of distributing capabilities among multiple facilities. Lastly, this workshop explored complex management topics in these facilities including instrumentation, user support services, data management, education and outreach, and workforce development capabilities. This publication summarizes the presentations and discussions from the workshop.
