An earthquake generates a tsunami if it is of sufficient force and there is violent movement of the earth to cause substantial and sudden displacement of a massive amount of water. Other cities are designing tsunami sanctuaries as well; Newport, Oregon, is turning a forested hill into a refuge that can accommodate 2,300 people. The city of Long Beach is planning to build a tsunami shelter that will resemble an armored hill. We therefore decided to use a continuum model, which is very powerful numerically and which gives results that are both conclusive and consistent with much of the experimental data," says Gaume, who heads EPFL's Snow Avalanche Simulation Laboratory (SLAB) and is the study's corresponding author.
