Tsunami is a Jampansese word that means ‘harbro wave’ It is in harbors that tsunamis do the most damage. We sometimes call tsunamis tidal waves though they’re not caused bytides. Oceanographers call tsunamis seismic sea waves. Whatever their name, those who have lived through them call them killers.
What actually is a tsunami? It’s a wave of water that sometimes follows earthquaks, volcanic eruptions, or underwater landslides, Not all tsunamis are large or destructive, In face , if your were out to sea, a tsunami could pass under your boar and your would hardly notice, THat’s because the ocean bottom is so deep . But as the wave gets closure to land, the ocean beomes shallower and begins to cuase the wave to crest. Some tsunamis can top 100 feet by the time they reach shore. The largest tsunami ever measured was 212 feet high.
