Maths with creativity...

The wave group has recently published work in the Computers and Fluids journal. The work focuses on the performance analysis of the internally developed tsunami code: Volna-OP2. Volna-OP2 is a robust and efficient code capable of simulating the complete life cycle of a tsunami whilst harnessing the latest High Performance Computing architectures.

An in-depth error analysis of the numerical scheme implemented in the code is given, with a novel decomposition of the numerical errors into the dispersion and dissipation components explored. Most tsunami codes exhibit amplitude smearing and/or phase lagging/leading, so the error decomposition shown here is a new approach and novel tool for explaining these occurrences. 

To date, Volna-OP2 has been widely used by the tsunami modelling community. In particular its

Towards Tsunami Threat Reduction for the Irish Coastline

The wave group are delighted to announce some newly published work in the journal Geosciences, which is part of a special issue: Advances in tsunami science towards tsunami threat reduction. The work focuses on the tsunami threat posed by the Lisbon 1755 earthquake event on the Irish coastline and was carried out in collaboration with Brian McConnell of Geological Survey Ireland. 

As there is no general consensus on the earthquake source parameters for the Lisbon event, multiple sources introduced in the literature are investigated. The tsunami hazard associated with the event is captured on three gradated levels. With the internally developed massively parallel tsunami code, Volna-OP2, used to simulate the resultant tsunami waves. Regional faster than real time simulations for the

Online Short Seminars: Dan Giles on Tsunami Warning Tools

My first task as the newly elected Vice President of the SIAM-IMA Dublin area student chapter was to produce a short video detailing my research. My research focuses on the development of operational tools for tsunami warning centres. As this video was aimed at introducing my research to a wide audience, it simply provides a brief introduction. So if you would like to learn more about the fascinating dynamics of tsunamis and how warning centres try to mitigate their damages, please check out the quick 4 min video here:

Making this short video doubled as great practice for the Flash Talk series run by UCD's Earth Institute. This series was organised to mark the 50th anniversary of Earth Day.
