\nStatement D is incorrect. The word “Tsunami” (\u6d25\u6ce2) is Japanese, meaning “harbour wave”.

\nTsunamis are giant waves caused by large-scale disturbances, most commonly underwater earthquakes, but also volcanic eruptions, landslides, and asteroid impacts. They are often referred to as seismic sea waves. The Pacific coasts, especially those bordering the seismically active “Ring of Fire”, are the most vulnerable to tsunamis. Tsunamis generate powerful waves that can cause immense destruction upon reaching coastlines.

\nUnlike wind-driven waves that only affect the surface, tsunamis are ‘full-column’ waves, meaning they displace the entire water column from the sea floor to the surface. In the open ocean, tsunamis have low amplitude but travel at high speeds. As they approach shallow coastal waters, their speed decreases, and their amplitude dramatically increases, leading to destructive wave heights. The term “tidal wave” is a misnomer, as tsunamis are not caused by tides.
