Short summary
In this paper, 20 explosive volcanic eruption scenarios of differing location and magnitude are simulated to investigate tsunami generation in Lake Taupō, New Zealand. A non-hydrostatic multilayer numerical scheme resolves the highly dispersive generated wavefield. Inundation, hydrographic and related hazard outputs are produced, indicating that significant inundation around the lake shore begins above 5 on the volcanic explosivity index.

This research explores improving wave forecasts in Aotearoa New Zealand, particularly at Banks Peninsula and Baring Head. We used detailed models and found that forecasts at Baring Head improved significantly due to its narrow geography, but changes at Banks Peninsula were minimal. The study demonstrates that local conditions greatly influence the effectiveness of wave prediction models, highlighting the need for tailored approaches in coastal forecasting to enhance accuracy in the predictions.

This research assesses tsunami exposure across New Zealand using detailed inundation maps for various tsunami scenarios. An efficient and accurate model highlights both urban centres and provincial regions as highly exposed, with significant impacts on buildings, infrastructure, and land. The findings provide critical understanding to help communities and decision-makers better plan for tsunamis, offering valuable insights for improving resilience and protecting assets nationwide.

Short summary
River depth is crucial in flood modelling, yet often unavailable or costly to collect. Estimation methods can fill this gap but have errors affecting flood modelling. Our study quantified flood-prediction uncertainty due to these errors. Among parameters in Conceptual Multivariate Regression (CMR) and Uniform Flow (UF) methods, river width corresponds to the largest uncertainty, followed by flow and slope. Also, the UF-formula depths have higher uncertainty than the CMR-formula ones.

Predicting how shorelines change over time is a major challenge in coastal research. We here have turned to deep learning (DL), a data-driven modelling approach, to predict the movement of shorelines using observations from a camera system in New Zealand. The DL models here implemented succeeded in capturing the variability and distribution of the observed shoreline data. Overall, these findings indicate that DL has the potential to enhance the accuracy of current shoreline change predictions.

On 10 February 2021 a magnitude 7.7 earthquake occurring at the southernmost part of the Vanuatu subduction zone triggered a regional tsunami that was recorded on many coastal gauges and DART stations of the south-west Pacific region. Beginning with a review of the tectonic setup and its implication in terms of tsunami generation in the region, this study aims to show our ability to reproduce a small tsunami with different types of rupture models and to discuss a larger magnitude 8.2 scenario.

The development of forecasting tools may help to limit the impacts of flash floods. Our purpose here is to demonstrate the possibility of using b-flood, which is a 2D tool based on shallow-water equations and adaptive mesh refinement.

Short summary
Volcanic eruptions can produce tsunamis through multiple mechanisms. We present validation cases for a numerical method used in simulating waves caused by submarine explosions: a laboratory flume experiment and waves generated by explosions at field scale. We then demonstrate the use of the scheme for simulating analogous volcanic eruptions, illustrating the resulting wavefield. We show that this scheme models such dispersive sources more proficiently than standard tsunami models.
