GP31D:
Understanding Active Earth Systems Through Combined MT/EM and Seismic Data Sets II Posters


Submit an Abstract to this Session


Session ID#: 54183

Session Description:
Seismic, Magnetotelluric (MT) and other electromagnetic (EM) methods are primary tools for imaging the properties of the crust and mantle, gaining insight into its structure and composition. Seismic and MT/EM investigations are increasingly closely coordinated, instead of isolated, providing better constraints of physical properties and structures of earth systems. For some years, efforts have focused on joint inversion of such hybrid datasets. Although challenged by the lack of a single, unifying equation of state to describe both elastic and electrical properties of Earth materials, significant advances are being made in reducing the ambiguity in interpreting the geologic meaning by jointly constraining separate seismic and MT/EM inversions with information from other geophysical data. In this session we focus on field experiments, laboratory measurements, theoretical developments and modeling applicable to the joint interpretation of seismic and MT/EM data and motivated by furthering our understanding active earth systems.
