Special Issue Information

Dear Colleagues,

The present Special Issue on “Modeling and Numerical Simulation of Tsunamis” aims to address all aspects of mathematical modeling and numerical simulation of tsunamis regardless of the mechanism by which they are generated: seismic source, aerial or underwater landslides, volcanic activity, asteroids or meteorological forcing (meteo-tsunamis). Research articles can cover a broad spectrum of topics, from case studies, model benchmarking (lab-based or reporting field cases), description and testing of new models or parameterizations, new source models and approximations, model inter-comparison, HPC in tsunami modeling, FTRT tsunami simulations, application to TEWS, high-resolution inundation simulations, probabilistic approximations (such as PTHA or PTF), IA, etc. Interdisciplinary work related to tsunami hazard assessment and risk analysis is also welcome. This Special Issue aims to collect the state of the art and most advanced knowledge in the very active area of ​​tsunami modeling and numerical simulation.

This study presents a scenario-based approach for identifying and comparing tsunami exposure across different sociopolitical scales. In Samoa, a country with a high threat to local tsunamis, we apply scenarios for the 2009 South Pacific tsunami inundation at different grid resolutions (50 and 10 m) to quantify building and road exposure at the national, district and village levels. We show that while the coarser 50 m model is adequate for use in the rapid identification of exposure at the national and district levels, it can overestimate exposure by up to three times more at the village level. Overestimation typically occurs in areas characterized by flat, low-lying, gentle-rising terrain. Overall, a 35% increase in buildings exposed to the 50 m model is observed compared with the 10 m scenario on southeast Upolu island. Similarly, a 31% increase in road exposure is observed for the 50 m scenario. These observations are discussed within the context of tsunami evacuation planning and logistics. Notwithstanding the variability in exposure, a precautionary approach leads us to conclude that while higher-resolution models are recommended where available data and/or financial resources permit, the absence of such datasets should not preclude the use of coarser hazard datasets in risk assessments. Finer-resolution models provide more credence in detailed local-level exposure evaluation. While the results of this study are specific to the Samoan context, the results can be applied to the multiscale assessment of tsunami risk exposure in similar hazard contexts. Full article
