Tsunami Runup Survey Data From The Taan Fjord Landslide Event Open
On 17 October 2015, a mountainside collapse at the terminus of Tyndall Glacier in southeast Alaska generated a landslide-triggered mega-tsunami. The landslide sent approximately 7.6 × 107 m3 of rock and glacial sediment into Taan Fjord, ab…
Variational Autoencoder Transfer Functions for Onshore Tsunami Hazard Curves Open
To quickly estimate tsunami hazards along the coastline, we present a data‐driven transfer function method to reconstruct onshore tsunami hazard curves from offshore hazard curves with corresponding topographic and bathymetric data. The tr…
EXPERIMENTAL STUDY OF INTERNAL SOLITARY WAVES INTERACTION WITH SURFACE SOLITARY WAVES Open
Internal solitary waves (ISWs) consist of a non-periodic single-crest profile resulting from the balance between non-linearity and dispersion. They can be a significant source of momentum transport in any stratified systems, such as oceans…
MODELING WIND WAVE DEVELOPMENT BASED ON PHASE-RESOLVING WAVE MODEL AND ITS APPLICATION TO TYPHOON JEBI in 2018 Open
The extreme wave hazards caused by typhoons in bays are increasing. An accurate deformation evaluation of typhoon-induced high waves in coastal regions is critical to mitigate disasters. High wave deformation is an intermediate phenomenon …
IMMERSIVE SIMULATION OF NATURAL HAZARDS FOR ENHANCED PUBLIC AWARENESS AND DISASTER PREPAREDNESS Open
Virtual reality (VR) has become a transformative force in understanding and responding to natural disasters. The TsuRuni project is at the forefront of this innovation, offering a virtual reality experience that simulates natural hazards, …

Forced and free waves of simulated volcanic meteo-tsunamis in the South China Sea Open
Volcanic meteo-tsunamis (VMTs) are rare, devastating phenomena first recognised after the 1883 Krakatau eruption in Indonesia and recently quantified following the 2022 Hunga Tonga-Hunga Ha’apai volcanic eruption in the Kingdom of Tonga. W…
Internal solitary wave generation using a jet-array wavemaker Open
This paper evaluates the experimental generation of internal solitary waves (ISWs) in a miscible two-layer system with a free surface using a jet-array wavemaker (JAW). Unlike traditional gate-release experiments, the JAW system generates …
Internal Solitary Wave Generation Using A Jet-Array Wavemaker Open

Quantifying surfcam imagery to measure the 2022 Hunga Tonga-Hunga Ha'apai tsunami along the California coast Open
On January 15, 2022, the eruption of the Hunga Tonga-Hunga Ha'apai volcano created a tsunami that reached a height of 20.5 m in the near field. The tsunami impacted the entire Pacific Ocean basin and was the largest tsunami to impact Calif…
NEARSHORE SCALAR TRANSPORT MODEL WITH VIRTUAL REALITY ENVIRONMENT Open
The importance of public awareness in disaster preparation has been emphasized in recent studies (Burningham et al., 2008; Sermet and Demir, 2019). Advances in virtual reality (VR) technology and graphical processor units (GPU) enables sim…
WAVE TRANSFORMATION AND RUNUP VARIABILITY DUE TO WAVE PHASE UNCERTAINTY Open
Wave runup is a significant portion of total water levels, particularly during storms (Sallenger, 2000). This makes accurate prediction of wave runup paramount. Wave runup can be estimated using simplified empirical models (e.g. Stockdon e…
INTERACTIVE VISUALIZATION FOR COASTAL HAZARDS Open
Augmented reality (AR) is a technology that integrates 3D virtual objects into the physical world in real-time, while virtual reality (VR) is a technology that immerses users in an interactive 3D virtual environment. The fast development o…
INVESTIGATING DEBRIS TRANSPORT DURING EXTREME COASTAL EVENTS Open
Past extreme coastal events such as the 2004 Indian Ocean Tsunami, the 2011 Tohoku Tsunami and the 2018 Hurricane Michael demonstrated the significance of understanding the debris generation and its transport and impacts during coastal dis…
DEEP LEARNING TO PREDICT TSUNAMI HEIGHT AT THE SHORELINE USING OCEAN BOTTOM PRESSURE DATA Open
Real-time tsunami prediction is a required component of a tsunami warning system. Several advances have been made to improve prediction in the tsunami warning process, including precomputed databases and the assimilation of deep-ocean obse…
FREQUENCY DISPERSION IN DEPTH-INTEGRATED MODELS THROUGH MACHINE LEARNING SURROGATES Open
Boussinesq- type wave models have the accuracy to resolve wave propagation in coastal zones, having the ability to capture nearshore dynamics that include both nonlinear and dispersive effects for relatively short waves. The accuracy of Bo…
Tsunami Runup and Inundation in Tonga from the January 2022 Eruption of Hunga Volcano Open
On January 15th, 2022, at approximately 4:47 pm local time (0347 UTC), several weeks of heightened activity at the Hunga volcano 65 km northwest of Tongatapu, culminated in an 11-h long violent eruption which generated a significant near-f…

Tsunami Runup and Inundation in Tonga from the January 2022 eruption of Hunga Volcano Open
On January 15th, 2022, at approximately 4:47 pm local time (0347 UTC), several weeks of heightened activity at the Hunga volcano 65 km northwest of Tongatapu, culminated in an 11-hour long violent eruption. The Kingdom of Tonga lies astrid…
Development of the Hydraulic-Control Wave-Maker for Study of Vertically-Variable Oceanographic Flows Open
This study aims to develop new experimental equipment to generate waves by using a system termed the Hydraulic-Control Wave-maker (HCW). This experimental device can completely mimic vertical flow distribution via an adjustable set of vert…
Modeling Infragravity Wave Runup and Spectral Properties Open
The purpose of this study is twofold: (1) to establish a method to model infragravity (IG) waves and their runup using a nonlinear, phase-resolving Boussinesq-type numerical model (COULWAVE) and (2) to discuss possible sources of error/con…
