Tsunamis triggered by volcanic eruptions are poorly understood because of the complex dynamics governing how falling rocks and ash interact with seawater to generate waves. As a result, it is difficult to anticipate whether a volcanic flow will trigger a tsunami and, if so, how big it will be. Researchers have used laboratory experiments to study this process, but little is known about how well these models mimic reality.
