In the open sea, tsunamis are generally not dangerous because their wave heights are often small and can pass unnoticed by ships. However, they travel at very high speeds, and their energy can extend to great depths. The danger escalates as they approach shallower coastal waters, where wave heights increase dramatically, posing significant risks to coastal communities and infrastructure. Thus, while open-sea tsunamis are not harmful, they become extremely dangerous near shorelines.
