Many geophysical problems are multiscale in nature, spanning several decades of spatial (or wavenumber) and temporal (or frequency) scales. This poses severe computational challenges for addressing both fundamental and practical problems of interest in areas such as seismology, geodynamics, geological material modeling and inverse techniques. Although recent advances in numerical methods and high-performance computing architectures have enabled some of these problems to be addressed at scales previously deemed impossible, unmet challenges still exist in incorporating multiphysics processes and in modeling large-scale problems over long time scales.

This mini-symposium solicits contributions in the broad field of computational methods relevant to geophysical problems with a special focus on:
1. Computational earthquake dynamics: From single events to multiple cycles; novel representations of bulk damage such as nucleation, extension, and coalescence of secondary fault surfaces; contact and other phenomena associated with irregular, non-planar fault surfaces
2. Multi-scale modeling of seismic wave propagation in heterogeneous media, from process-zone scales to regional and global domains
3. Modeling fluid-solid interactions in the sub-surface across scales (e.g. hydraulic fracturing, mechanics of ice sheets, mantle convection, plate dynamics, etc.)
4. Simulations of tsunamis and storm surge
5. Inverse methods
