Spatiotemporal Seismic Hazard Assessment Using VQ-VAE and Seismic Statistical Features

arXiv:2606. 10069v1 Announce Type: new Abstract: In this paper we build upon a previous study in which we demonstrated, using XGBoost and earthquake catalogue data from Japan and Chile, that a set of 60 seismic statistical features (SSFs) had much greater predictive value than a set of 428 generic time series features from the tsfresh package.

AUWave: A Data-Driven Model for Reconstructing Significant Wave Heights Using Sparse Observations

AUWave is a hybrid deep‑learning framework that reconstructs high‑resolution regional significant wave height (SWH) fields from sparse buoy observations. By combining a station‑wise encoder with a multi‑scale U‑Net enhanced by self‑attention, it outperforms a baseline model, especially when more than one buoy is available, and identifies critical anchor stations through buoy ablation studies. Cross‑basin tests in the Atlantic and Pacific demonstrate the model’s robustness and portability, suggesting its applicability for operational ocean monitoring and data assimilation.

Generated storm lifecycles fill the rare-event tail of short rainfall records

The paper introduces StormGen, a generative machine‑learning model that expands the initial hours of an observed storm into full, physically plausible hourly rainfall lifecycles within minutes. Tested on a decade of southeast Texas rainfall, StormGen accurately reproduced the most severe storms, generating close counterparts for 4–5% of the top 2% of events, outperforming stochastic storm transposition. Remarkably, the model reconstructed Hurricane Harvey’s lifecycle and extreme catchment totals from a single hour of data, even though the event was not in the training set.
