The National Science Foundation (NSF) is offering a federal grant opportunity titled "Structure and Physics of the Solid Earth," aimed at advancing fundamental knowledge about the Earth's dynamic processes and their implications for geohazards. This program supports research across various disciplines, including structural geology, tectonics, and geophysics, focusing on understanding natural hazards such as earthquakes and mass flows, as well as the Earth's formation and magnetic field. With an estimated total program funding of $22 million and approximately 75 awards expected, proposals can be submitted at any time, and interested applicants may contact NSF grants.gov support at grantsgovsupport@nsf.gov for assistance.
