Physical Properties of Earth Materials (PPEM)

About PPEM Steering Committee


The PPEM Steering Committee serves this community by bringing together scientists who develop and explore applications of rock mechanics and materials science approaches to geophysical problems, promoting the Gordon Conference on Rock Deformation, and encouraging the organization of symposia and workshops within and outside the AGU. PPEM also sponsors an annual dinner at the Fall AGU meeting and issues an annual Newsletter, while it promotes participation in the greater MRP Community and outreach to the rock mechanics and materials science communities outside of AGU.

The PPEM Steering Committee reports to MRP Committee of AGU, and furthers the goals of MRP of scientific advancement and innovation in fundamental studies of Earth materials, exchange of ideas across disciplines, and applications of Earth materials studies to plate dynamics, fault mechanics, development of geologic structures, and the physics of the deep Earth’s interior.
