In August 2022, USSD published a report on analysis of Seismic Deformation of Embankment Dams.

Per the foreword, "This report is intended to provide guidance on the evaluation of seismic deformations of embankment dams and on the use of numerical analysis procedures for such evaluations. It is intended to serve as a reference on available analysis methods for consultants, regulators, and owners involved in performing, reviewing, and procuring analyses of seismic stability and deformations of embankment dams. Because engineering practice in this field will likely continue to evolve rapidly, this guidance is expected to require periodic review and updating in the future. The document was prepared by the Committee on Earthquakes of the United States Society on Dams (USSD) and provides a consensus view of the Committee on current United States practice for analysis of embankment dam seismic deformations.
