SubRidge: a Subduction-to-Ridge Model with SyntheticSeismic Waveforms for Benchmarking

We present a geodynamic model that simulates the co-evolution of a mid-ocean ridge and adjacent subduction zones. From the dynamic evolution of this system, we derive spatially variable 21 elastic constants and generate a suite of synthetic seismic waveforms. These data are designed to support a wide range of benchmarking and exploratory applications in geophysics and seismology, including (but not limited to) seismic tomography methods (e.g., travel-time and full-waveform inversion), sensitivity analyses of anisotropy, and studies of wave propagation and imaging artifacts under controlled conditions. These waveforms capture key features of upper mantle dynamics, including the effects of anisotropy, slab geometry, and mantle heterogeneity on wave propagation. The dataset includes diverse source-receiver configurations, allowing users to tailor tests to their specific applications and research objectives. By combining a dynamically consistent geodynamic model with synthetic seismograms, this work provides a robust and flexible resource for developing, testing, and evaluating geophysical methods.
