Japanese Tsunami Research: Understanding the Power of Killer Waves

The video discusses a Japanese tsunami research project aimed at recreating the force of tsunamis to better understand their behavior. The project involves creating the world's tallest man-made tsunami wave to gather data that could improve seawall designs and evacuation plans. The research includes experiments on wave impact, seabed churning, and building material resistance. Innovative seawall designs are being tested, including one that rises automatically in response to a tsunami's force.
