Numerical Method Makes Simulating Landslide Tsunamis Possible
Researchers from Tohoku University have developed a numerical method that paves the way for simulating landslide tsunamis.
They describe the method in "MPM-FEM Hybrid Method for Granular Mass-Water Interaction Problems," published in the journal Computational Mechanics. The simulation method can express the complex interaction between soil structures and liquids.
"Our novel method couples together two computational methods that analyze the interactions of solids and liquids: the finite element method (FEM) along with the material point method (MEM)," says Kenjiro Terada, professor at Tohoku University's International Research Institute of Disaster Science and co-author of the study.
Using the algorithm, the researchers were able to simulate a wave mimicking a submarine granular collapse and a wave induced by a subaerial slide over an inclined plane.
