A tsunami is a series of waves caused by the displacement of a large volume of water, generally in an ocean, that is usually triggered by large earthquakes on the seafloor where slabs of rock move past each other suddenly. Tsunamis can be categorized as local if the underwater earthquake event occurs within 100 km of the resulting land damage.

2. What is tsunami
• A tsunami or tidal wave, also known as a seismic sea wave, is
a series of waves in a water body caused by the displacement
of a large volume of water, generally in an ocean or a large
lake

3. Cause of tsunami
• Most tsunami are caused by large earthquakes on the sea
floor when slabs of rock move past each other suddenly,
causing the overlying water to move. The resulting waves
move away from the source of the earthquake event.

5. Types of tsunami
Local tsunami
• local tsunami is a tsunami that causes damage in relatively close
proximity to the tsunami-causing event. Specifically, the
underwater event -- usually an earthquake -- that produces a local
tsunami happens within 100 km, which is a little over 60 miles, of
the land damage that result.
