*Session description:*
The devastating mega-tsunamis of the past decade (Indian Ocean 2004, Chile
2010, Japan 2011) have triggered a large wave of research focused on this
kind of natural disaster. A number of new tools from computational sciences
were introduced into the community and today the simulation based knowledge
creation has accelerated into a new level of capabilities for
near-realistic complex simulations. This session aims to display the state
of the art in today’s complex modeling capabilities in simulating realistic
source mechanisms and tsunami coupling by combining novel mathematical
equation sets, advanced simulation techniques and scientific computing
tools to solve high fidelity modeling problems. 3D physics based rupture
models for earthquake-induced tsunami events represent one such example,
where it is possible to simulate realistic dynamic ruptures, including the
earth crust displacements, seismic wave release and dispersion for
realistic geometrical set-ups. Modeling of failure mechanism due to slope
instability and induced submarine landslide dynamics adopted for tsunami
modeling purposes reveals more complex volume emplacement processes than
traditional block sources. Source mechanisms related to volcanic activity,
such as pyroclastic flows entering the water, and underwater explosions
call for yet another type of advanced modeling techniques like two-phase
flow techniques. These lead to better coupling results for the interaction
of solids and fluids in the excitation of tsunami waves. The list of
examples could be extended. An important question is how to incorporate
such complex sources in probabilistic tsunami hazard assessment (PTHA) in
order to give societies proper guidelines for future planning and
mitigation measures. We invite abstracts that present such an example: a
new simulation strategy, a novel equation set, a high-performance
computational tool, an advanced numerical method for realistic complex
tsunami source interaction, as well as studies assessing the sensitivity of
the modeled tsunami impact to the complexity and accuracy of the source
model, or examples of PTHA considering complex source models.
