Ground motion estimation and subsurface exploration are main research areas in
computational seismology, they are fundamental for implementing earthquake engineering
requirements and for modern subsurface reservoir assessment. In this study we propose a
workflow for discretizing, simulating and visualizing near source ground motion due to
earthquake rupture. For data generation we use an elastic wave equation solver called SeisSol
based on the Discontinuous Galerkin formulation with Arbitrary high-order DERivatives
(ADER-DG). SeisSol is capable of highly accurate treatment of any earthquake source
characterization, occurring on geometrically complex fault systems embedded in geologically
complicated earth structures. We then visualize the results with two tools: VisIt (“a free
interactive parallel visualization and graphical analysis tool for viewing scientific data”) and
Avizo (“The 3D Analysis Software for Scientific and Industrial data”). We investigate each
approach, include our experiences from model generation to visualization in highly
immersive environments and conclude with a set of general recommendations for
earthquake visualization.
