In 1908, the largest earthquake ever recorded in Europe hit Southern Italy, wiping out the entire coastal town of Messina. Once the shaking had stopped, survivors thought they were safe until a massive tsunami followed minutes later. Even today, the exact cause of the tsunami is debated in the scientific community. In this episode, we talk to Dr. Lauren Schambach from the University of Rhode Island about what her computational simulations of the Messina tsunami have told her, and what that means for people living along the coastlines around the world.
