A

The

Japan
has

It

where
most
,
the
principal
cause
of
tsunamis
,
are
born
.
When
two
tectonic
plates
together
,
the
resulting
earthquake
sends
an
enormous
burst
of
energy
up
the
ocean
,
enormous
quantities
of
water
.
A
series
of
waves
in
all
directions

In

these
waves
travel

up
to
miles

Unlike
waves
,
a
tsunami
wave
doesn't
and
break
.
Instead
,
it
advances
like
a
wall
of
water
that
crashes
over
the
and
everything
in
its
way
reaching
even
as
far
as
a
mile
.

caused
when
the
wave
,
dragging
everything
in
it
back
underwater
and
most
tsunamis
have
multiple
waves
,
each
arriving
anywhere
from
10
to
minutes
after
the
first

a
tsunami
that

Warning
Center
in

on
call
24
hours

to
a
similar
tragedy
from
happening

Scientists
tremors

quakes

If
a
quake
big
enough
to

it
is
their

The

move

wait
