VISUAL REPRESENTATION OF SEISMIC DATA

The amount of Geoscience data available to researchers has seen an exponential growth in the past few decades and continues to grow at this rate. This growth is a direct result of advancements in monitoring, observation and recording of data through satellite and field specific sensors. The drastic reduction in compute and storage costs over the same time frame has spurred the majority of this growth. This data collected through observation and simulation enable analyses at significantly expanded scope and resolution. We present a few novel visualization techniques and case studies of simulated and observed seismic data, and also show how existing tools from the general animation domain can be applied to create visualizations in the Geosciences. The case studies are visualizations of the TeraShake1&2 and Puente Hills seismic simulations, the 1906 San Francisco Earthquake and a visualization of an experimental data captured from the physical shaking of a seven story building.
