23. Are all tsunamis disastrous?

The majority of tsunamis are caused by huge earthquakes on or near the seabed, but not all seaquakes caused tsunamis. Meanwhile, not all tsunamis are big enough to be disastrous. The degree of damage that can be inflicted by a tsunami also depends on the local littoral landforms or the strike of accidental huge waves in the coastal area so as to cause loss of life and property.
