The Committee on Solid Earth Geophysics serves as the focal point for community discussion and community-agency interaction on issues related to the structure, dynamics, and evolution of the Earth. Its mission is to encourage understanding of Earth structure, dynamics, and evolution; review research activities that contribute to federal agency missions in seismology, geodesy, and geodynamics; address the transfer of seismological and geodynamics knowledge to areas of public welfare and national needs; foster long-term national efforts to collect, store and disseminate related data; and foster long-term national efforts to monitor geodynamical events and nuclear testing treaties.
