Tailoring tsunami Digital-Twins for future Destination Earth integration
Bibliographic record
Abstract
Probabilistic Tsunami Forecasting (PTF) combines early estimates of earthquake parameters with large ensembles of urgent shallow water tsunami propagation simulations using the GPU based Tsunami-HySEA model (Selva et al. 2021, Nature Commun.). The present version of the PTF is initialised by the earthquake information, but not updated further with new data. In the recently started Horizon Europe project DT-GEO, this PTF is presently being upgraded to a Digital Twin. The first and essential upgrade to realise the Digital Twin is continuous data assimilation enabling a close to real time synthesis of data products and a set of numerical models that allow an updating of the model forecast as new data are continuously assimilated into the model. In DT-GEO, an extended set of data sources, including improved earthquake solutions, sea level tsunami data, and GNSS, will be integrated. A second objective of the PTF is to implement a modularised Digital Twin Component that allows for the inclusion of improved wave and source physics through dispersion, non-hydrostatic tsunami generation, inundation, improved earthquake physics, and cascading earthquake triggered landslide tsunamis. The model will be tested at site demonstrators, in the Mediterranean Sea for eastern Sicily and Samos, and in the Pacific Ocean for Chile and eastern Japan. The presentation will explain how the PTF as it works today, followed by an outline of the design of the components in the Digital Twin, as well as briefly describing initial improvements and plans for further development, including potential integration into Destination Earth. This work is supported by the European Union’s Horizon Europe Research and Innovation Program under grant agreement No 101058129 (DT-GEO, https://dtgeo.eu/).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
