2. TSUNAMI
A tsunami also known as a seismic sea wave
or as a tidal 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. Earthquakes, volcanic eruptions
and other underwater explosions (including
detonations of underwater nuclear devices),
landslides, glacier calvings, meteorite impacts
and other disturbances above or below water
all have the potential to generate a tsunami.

3. HOW DO TSUNAMIS FORM?
• When movement along a
fault moves the seafloor
upward, water is also
pushed upward and
becomes tsunami waves.
As the waves approach
shallower water, they
become higher.
5. THAT EARTHQUAKE OCCUR IN JAPAN
• On March 11, 2011, a magnitude-9 earthquake shook
northeastern Japan, unleashing a savage tsunami.In Japan,
residents are still recovering from the disaster. Radioactive
water was recently discovered leaking from the Fukushima
Daiichi Nuclear Power Plant, which suffered a level 7 nuclear
meltdown after the tsunami. Japan relies on nuclear power,
and many of the country's nuclear reactors remain closed
because of stricter seismic safety standards since the
earthquake. Four years after the quake, about 230,000 people
who lost their homes were still living in temporary housing,
Japan's Reconstruction Agency said
