In this video from the HPC User Forum in Tucson, David McCallen from LBNL describes how exascale computing capabilities will enhance earthquake simulation for improved structural safety. “With the major advances occurring in high performance computing, the ability to accurately simulate the complex processes associated with major earthquakes is becoming a reality. High performance simulations offer a transformational approach to earthquake hazard and risk assessments that can dramatically increase our understanding of earthquake processes and provide improved estimates of the ground motions that can be expected in future earthquakes.”
