The word "tsunami" is a direct borrowing from Japanese, where 津 (tsu) means "harbor" and 波 (nami) means "wave." Historically, Japanese fishermen coined the term after returning to shore to find their harbors devastated by these massive waves, despite not witnessing them at sea. The term entered English in the early 20th century as scientific understanding of the phenomenon grew. Unlike "tidal wave," "tsunami" accurately reflects its seismic origin rather than tidal forces.
The tsunami devastated coastal communities, leaving thousands homeless.
Scientists issued a tsunami warning after the undersea earthquake.
The political scandal created a tsunami of public outrage.
Traditional Japanese woodblock prints often depict tsunami waves.
After the tsunami receded, the shoreline was littered with debris.
