On the Modelling of Tsunami Generation and Tsunami Inundation

Procedia IUTAM, 2014
While the propagation of tsunamis is well understood and well simulated by numerical models, there are still a number of unanswered questions related to the generation of tsunamis or the subsequent inundation. We review some of the basic generation mechanisms as well as their simulation.

Inundation flow velocity of tsunami on land

Island Arc, 2010
AbstractAn estimation of tsunami inundation flow velocity is one of the most challenging issues among tsunami research. Based on field data of inundation depth and inundation flow velocity u estimated using Bernoulli's theorem and inundation depth, fundamental characteristics of the relationship between inundation flow velocity and inundation depth are

Tsunami inundation hazard across Japan

International Journal of Disaster Risk Reduction, 2020
Abstract Japan faces the world's highest tsunami hazard and risk due to its tectonic environment, high population density and exposure concentration along its coastlines. It is therefore of paramount interest to quantify and differentiate absolute and relative tsunami hazard and risk on a countrywide scale.

A Numerical Model for Tsunami Inundation

2023
A two-dimensional and time-dependent numerical model was developed that calculates the land inundation of a tsunami. The model solves long wave equations that include bottom friction terms. A coordinate transformation was used to allow the model to employ a smoothly varying grid that allows cells to be small in the inundation region and large in the ...

Tsunami inundation modelling using RiCOM

Australian Journal of Civil Engineering, 2011
The New Zealand coastline faces the risk of tsunami from a variety of sources, including remote and local earthquakes, submarine landslides, and volcanoes. Palaeotsunami studies indicate New Zealand has undergone periods of catastrophic tsunami activity, such as in the 1500s. It is important to be able to quantify the hazard posed by tsunamis.

A GPU-Based Simulation of Tsunami Propagation and Inundation

2009
Tsunami simulation consists of fluid dynamics, numerical computations, and visualization techniques. Nonlinear shallow water equations are often used to model the tsunami propagation. By adding the friction slope to the conservation of momentum, it also can model the tsunami inundation.

Conditional Expected Tsunami Inundation for Hawaii

Journal of the Waterways, Harbors and Coastal Engineering Division, 1975
Values were reported for a priori estimates of expected tsunami inundation — conditioned by values for epicenter location and tsunami magnitude. Those values of conditional expected tsunami inundation (CETI) were restricted to coastal locations having historical observations of tsunamis.

Short-Term Inundation Forecasting for Tsunamis

2003
Since 1997, PMEL has been involved in the R’D effort to provide tsunami-forecasting capabilities for the Pacific Disaster Center (PDC) in Hawaii. As a part of this effort, modeling tools for the short-term forecasting, and assessing the risk of tsunami inundation have been developed.

Combining Tsunami Hazard and Vulnerability on the Assessment of Tsunami Inundation Probability in Taiwan

Journal of Earthquake and Tsunami, 2014
As earthquake and tsunami are closely related, the probability of tsunami hazard had been done by extending the approach used in earthquakes. However, the hazard of tsunami depends also on the vulnerability of neighboring structures and hence its hazard and vulnerability should not be assessed separately.

Development of an online tool for tsunami inundation simulation and tsunami loss estimation

Continental Shelf Research, 2014
Abstract The devastating impacts of the 2004 Indian Ocean tsunami highlighted the need for an effective end-to-end tsunami early warning system in the region that connects the scientific components of warning with preparedness of institutions and communities to respond to an emergency. Essential to preparedness planning is knowledge of tsunami risks.
