Probabilistic Tsunami Heights Model using Bayesian Machine Learning

초록

Tsunamis, which are long-period oceanic waves, are known as catastrophic disasters and can cause large losses of human life, as well as property damage. To date, tsunami research has focused on developing numerical models to predict accurate tsunami heights and run-up heights, because hydraulic experiments are associated with high costs for laboratory installation and maintenance. Recently, artificial intelligence (AI) has been progressed, demonstrating enhanced performances in science and engineering fields. This study explored the use of AI to estimate maximum tsunami heights. Bayesian machine learning, a neural network method, was employed, and numerical simulation was performed for historical and probable maximum tsunami events.
