Geoffrey Ely
My research interests are in numerical simulations of earthquake rupture dynamics, wave propagation and ground motion using high-performance computing and visualization. I am currently working on a range of simulations for the most probable large earthquake scenarios in southern California.
Projects
SORD: Support Operator Rupture Dynamics code.
CVM: Parallelization and bug fixes to the SCEC Community Velocity Model versions 3.0 and 4.0.
