The planned observational infrastructure and data acquisition within DEFORM pose excellent opportunities to advance earthquake physics but require a central access point for earthquake simulation expertise. The project Kyma (κύμα, Greek for wave) aims to enhance our understanding of tsunamigenic earthquake sources and earthquake-tsunami interactions, focusing on the Kefalonia Transform Fault System (KTFS) as a case study, while providing the earthquake modeling backbone for DEFORM. It will develop innovative modeling workflows to bridge time scales from seismic cycles to seismic and tsunami wave propagation, combining dynamic rupture, seismic cycle, and tsunami modeling. Specifically, integrated seismic-cycle, dynamic-rupture, and tsunami modeling will be developed and adapted to complex multi-fault systems, enabling seismic cycle-informed dynamic rupture and tsunami modeling. The project will advance 3D tsunami-earthquake simulation techniques, with new automatic CAD workflows, comprehensive analysis to better characterize complex 3D tsunami generation effects, and efficient approximation methods for 2D tsunami models. It will also improve our understanding of signals recorded by ocean-bottom and 6DOF instruments through parametric studies. Earthquake and tsunami signatures will be characterized at planned amphibious instrumentation sites for rapid event detection and characterization. Additionally, a dataset of labeled tsunamigenic and non-tsunamigenic synthetic signals will be generated, and initial exploratory analysis using machine learning techniques will be conducted. This comprehensive approach will contribute to the DEFORM priority program's goal of developing physical geohazard models that explain fault system complexities and lithosphere deformation across various time scales.
