Bōsai, Tsunami
… of the islands is incredibly vulnerable to mega-tsunamis as the country is situated at the collision plate forming active troughs capable of generating forcefully destructive tsunami waves. The Great East Japan Earthquake that hit the Tohoku region in 2011 exposed disaster planning challenges and …

Tsunami Warning System
<p>The effects of a tsunami on a coastline can be devastating. In an attempt to mitigate the damages caused by tsunamis, and to provide coastal communities with evacuation alerts, it is essential to have early warning systems installed offshore. Tsunami early warning systems can detect the …

Evaluation of Tsunami Design Codes and Recommendations for Bridges Susceptible to Tsunami Inundation
Much of the past tsunami research has focused on inundation modeling, evacuation strategies and to a lesser extent, building design. Although many of the bridges that lie within possible tsunami inundation zones provide critical lifelines to coastal communities, the effects of tsunamis on …

Tsunami monitoring using airglow imaging systems
Tsunamis generate internal gravity waves (IGWs) that propagate vertically into the atmosphere and can create detectable signatures in the ionosphere. These signatures have consistently been observed in the presence of a tsunami for over a decade in the total electron content and for over 5 years in …

Tsunami Excitation Estimation from Real-time GNSS
Tsunami early warning systems currently comprise modeling of observations from the global seismic network, deep-ocean DART buoys, and a global distribution of tide gauges. While these tools work well for tsunamis traveling teleseismic distances, saturation of seismic magnitude estimation in the …

Improved Tsunami Modeling Via q-Advanced Special Functions
… and the Korteweg-de Vries equation in modeling tsunamis. The model improves existing tsunami models and is compared to data collected from the 2011 Japanese tsunami. The main results show that one can modify existing q-advanced functions to obtain more accuracy in the forcing of a tsunami, and, …

Experimental Study of Tsunami-Induced Loads on Bridges
… Ocean, which makes it quite vulnerable to tsunami events. Over 14 major tsunami events struck the world’s coastlines, causing death and economic destruction, between 1990 and 2000 (Bryant, 2014), and at least 32 tsunami have been recorded in New Zealand since 1840 (De Lange et al., 1986). …

Forward and Inverse Modeling of Tsunami Sediment Transport
Tsunami is one of the most dangerous natural hazards in the coastal zone worldwide. Large tsunamis are relatively infrequent. Deposits are the only concrete evidence in the geological record with which we can determine both tsunami frequency and magnitude. Numerical modeling of sediment transport …

Qualitative study of trauma outcomes among Acehnese tsunami survivors
… individuals were interviewed about their post-tsunami difficulties in the Indonesian province of Aceh. Contrary to our expectations, participants reported significant numbers of almost all DSM-IV-TR symptoms of PTSD and depression. Although the expressions of illness symptoms were colored by …

Numerical Investigation of Tsunami-Borne Debris Interaction with Coastal Bridges
The destructive potential of tsunamis has been well-documented in past events such as the 2004 Indian Ocean and 2011 Great East Japan tsunamis, which resulted in extensive damage to coastal regions including the destruction or damage of numerous bridges. These transportation links are particularly …

The silent tsunami: addressing community college food insecurity in Texas
This study explores the issue of food insecurity within community colleges in Texas and highlights administrator’s responses toward best and most promising practices and challenges in addressing food insecurity. The research was guided by complex adaptive systems theory and cynefin. Food insecurity …

Tohoku Topo-Urbanism : oblique community form in post-Tsunami Japan
… form and resilient reconstruction in Post-Tsunami Japan. In its wake, the 2011 Tsunami left a redefined landscape and enormous questions about the future of people and place. Since then, the Japanese Government's plans for reconstruction put a moratorium on housing in lowland areas, …

Transitional relief housing for tsunami victims of Tamil Nadu, India
In the wake of the recent tsunami that swept across Asia, there is a dire need to salvage and rebuild the lives and livelihoods that were swept away. The aim of this thesis project is to design and model a transitional shelter for the Indian region of Tamil Nadu. Tamil Nadu is located on the …

The 2004 and 1861 Tsunami Deposits on Simeulue Island, Western Sumatra
<p>Megathrust earthquakes and associated tsunamis along the subduction zone along western Sumatra represent a significant seismic hazard that is not well understood. I present the results of mapping, paleoseimologic, and geochronologic studies of tsunami deposits exposed on Simeulue Island, western …

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 …

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. …
