Bayesian three-dimensional seismic travel-time tomography for active- and passive-source seismic data using physics-informed neural networks

Summary Accurate three-dimensional (3D) seismic velocity modeling through seismic travel-time tomography using both active- and passive-source data provides critical underpinning models for seismicity monitoring and hazard assessment. Because travel-time tomography is an inherent...

Extreme sea level inundation maps for Vanuatu

Abstract Extreme sea level (ESL) inundation poses a growing risk for Pacific Island Countries (PICs), yet few nationwide inundation maps exist to inform national-scale flood risk management. This study presents a new dataset of ESL inundation maps for Vanuatu. ESL inundation was...

Changing Antecedent Land‐Surface Conditions Can Amplify Future Heat Extremes Across New Zealand

Abstract Extreme heat in New Zealand is projected to intensify faster than mean warming, but the mechanisms remain unclear. Using dynamically downscaled CMIP6 projections, we investigate whether land–surface moisture constraints contributes to future heat‐extreme intensification...

Fifteen years of regional climate downscaling in CORDEX-Australasia

Regional climate modelling plays a central role in understanding and projecting climate change across Australasia, a region characterised by complex topography, diverse climate regimes, and high exposure to climate extremes. Over the past fifteen years, CORDEX-Australasia has coo...
