AI summaryThis program funds research on the structure and physics of the solid Earth, including earthquakes, tectonics, mantle and core processes, geophysics, and related interdisciplinary work. It also supports community experiments, planning activities, workshops, and projects that connect the solid Earth with other planets. Proposals may come from U.S. two- and four-year colleges and universities and certain U.S.-based nonprofit non-academic organizations; there are no limits on who may serve as PI or on the number of proposals per organization or PI. The announcement estimates 60 to 75 awards with total funding of $22,000,000, and the award type is continuing grant or standard grant. There are no geographic set-asides stated, but declined proposals generally cannot be resubmitted for one year unless substantially revised, with exceptions requiring prior approval.

What it funds
Official description from grants.gov
The Structure and Physics of the Solid Earth Program (SPSE) aims to advance fundamental knowledge about the ongoing dynamical processes over the age of the Earth that evolve the structure of planet Earth and underpin geohazards. SPSE supports research at all temporal and spatial scales, from the Earth's core to its crust. Through laboratory, field, theoretical, and computational studies, the program encompasses a wide range of disciplines including structural geology, tectonics, and geophysics. Research in these areas can help improve our understanding of natural hazards including earthquakes and mass flows, as well as Earth’s formation and its magnetic field.
