Numerical Perspective on Tsunami Hazards and Their Mitigation by Coastal Vegetation
Tsunamis are among the most threatening natural hazards that can affect coastal communities and infrastructures. In order to provide useful information for coastal protection, one of my aims in this dissertation is to identify the physical metrics that better represent the damage cause by tsunamis. …

Physical Modelling of Instability in Granular Soils and Tsunami Hazards Associated with Coastal Slope Failures
… have the potential to create significant tsunami hazards. As an inherently coupled solid-fluid interaction problem, accurate assessment of these hazards requires an understanding of the triggering mechanisms of failure to predict the consequential wave generation upon impact. With respect …

Catastrophic Tsunamis In the Indonesian Archipelago
Tsunamis are not rare events for the Indonesian Archipelago as a consequence of four major plate boundaries that meet and collide, and producing highly active seismic zone that is mostly located under the sea. The ‘tsunami season’ within this region started in 1992 at Hading Bay, Flores Island, …

INTEGRATING GEOPHYSICAL METHODS TO STUDY SUBDUCTION ZONE PROPERTIES, ACTIVE FAULTING IN A VOLCANIC FIELD, AND VOLCANO LANDSLIDE HAZARDS
… influence on earthquake, volcanic, and landslide hazards from the trench to the volcanic arc. Specifically, I use seismic reflection data, earthquake focal mechanisms, magnetics, and electromagnetics to study three actively deforming regions: 1) the Cascadia subduction zone deformation front in …

Mapping and Modeling the Seattle Fault Tsunami Inundation in Puget Sound
… communities of Puget Sound are susceptible to tsunami inundation from multiple sources. Two sources of potential tsunami hazard that threaten the region are earthquakes on crustal faults in the Puget Lowlands, or earthquakes originating on the Cascadia subduction zone. This study investigated …

Multi-hazard performance of bridge timber piles retrofitted with fiber reinforced polymer composites
… models for bridges subject to earthquake-tsunami hazards. Under earthquake-tsunami loading considerations, a sequential analysis framework is used to perform nonlinear dynamic time history analyses and tsunami impact simulations using the particle finite element method (PFEM). Failure …

The Amplification of Tsunamis by Mercury Bay, New Zealand
The east coast of New Zealand is exposed to tsunami hazards, which are generated by both distant and near tsunamigenic sources. The impact of tsunami varies along the coast depending on the source region and the amount of local attenuation or amplification. Some regions have consistently amplified …

Landslide generated tsunamis : numerical modeling and real-time prediction
Submarine landslides can generate local tsunamis posing a hazard to human lives and coastal facilities. Two major related problems are: (i) quantitative estimation of tsunami hazard and (ii) early detection of the most dangerous landslides. This thesis focuses on both those issues by providing …
