 A tsunami starts when a huge volume of water
quickly shifted this rapid movement can happen as
the result of an underwater earthquake (when the
sea floor quickly moves up or down (a rock slide, a
volcanic eruption, or another high – energy event.
A tsunami can travel at well over
970 kph (600 mph in open ocean
– as fast as a jet flies . It can take
only a few hours for a tsunami to
travel across entire ocean. A
regular wave ( generated by the
wind) travels up to about 90
km/hr.
Tsunamis have an extremely long
wavelength ( wavelength is the
distance between the crest and
top of the wave and the crest of
the next wave )—they can be a
hundred miles long between to
successive waves ( is also very
long about one hour deep.)
 Tsunamis are very rare . There are roughly six major
tsunamis each century. Tsunami is a Japanese word
meaning harbor wave.
•Tsunami warning systems exist in many
places around the world. As scientist
continuously mentor seismic activity(
earthquakes. A series of buoys float off
the coast and monitor changes in sea
level . Unfortunately , since tsunamis are
not very tall in height when they are out
at sea. Dentation is not easy and there
are many false alarms , sirens at affected
beaches my be activated – do not ignore
them!!!!!!!!!
“ A tsunami will come
suddenly. So when you
feel a strong
earthquake, leave the
shore immediately!!”
