Urgent Supercomputing of Earthquakes in the ChEESE Project

Workshop:Urgent HPC: HPC for Urgent Decision Making

Authors: Josep de la Puente (Barcelona Supercomputing Center (BSC))

Abstract: Physics-based simulations of earthquakes can be very precise at outlining the shaking produced by an earthquake with high spatial resolution. Such simulations take into account aspects such as directivity, topography or basin resonance which can crucially alter the affectation of an event. Within ChEESE we have developed an urgent computing workflow that can connect to some of the most powerful 3D seismic simulation packages in order to produce shake estimates within hours to minutes once the event has been registered. ChEESE is the EU's Center of Excellence for Exascale on Solid Earth (
