<i>In Situ</i> Visualization of Regional-Scale Natural Hazards With Galaxy and Material Point Method

Visualizing regional-scale landslides is essential to conveying the threat of natural hazards stakeholders and policymakers. Traditional visualization techniques are restricted post-processing a limited subset simulation data not scalable rendering models. In situ technique in real-time, i.e., visuals tandem while running. This study develops N:M interface architecture visualize landslides. We demonstrate scalability by simulating long runout 2014 Oso landslide using Material Point Method coupled with Galaxy ray tracing engine 4.2 million material points as spheres. has an amortized runtime increase 2% compared non-visualized simulations. The developed approach can achieve minimal impact on process.
