Title: How the ChEESE CoE is Developing HPC-based Software and Services to Address Natural Hazards

Geohazardous phenomena (e.g. earthquakes, eruptions, tsunamis) require emergency simulations that need to be solved under strict time constraints. In these urgent computing scenarios, supercomputing can reduce substantially the time-to-solution and hence have the potential to substantially transform the way society deals with early warnings, short-term forecasts and emergency management. The EuroHPC ChEESE Centre of Excellence (2023-2026, Grant Agreement No 101093038) is preparing 11 open source flagship applications to perform on large pre-exascale research infrastructures, including the deployment of urgent computing downstream services. The project aims at enabling up to 4 services on target tier-0 EuroHPC pre-exascale architectures (Leonardo, LUMI, MareNostrum-5) for an emergency access mode during 

high-impact geohazardous events (earthquakes, tsunamis and volcanoes) including related technical challenges and access policy recommendations. Applications include urgent computing for earthquakes using AI/ML-based approaches, tsunamis, atmospheric dispersal of volcanic ash at multiple scales, and phreatic eruptions to be potentially used in the framework of a volcanic unrest. A service co-design approach is adopted together with a board of potential end-users through trials and exercises. This contribution summarizes the current status and the service implementation roadmap.
