the science of tsunamis in 2004 the
world's most destructive earthquake
occurred in human history this
earthquake occurred in sumatra indonesia
the earthquake had a magnitude of 9.1 to
9.3 and is the third largest recorded
earthquake it had the energy of 23 000
hiroshima type atomic bombs this
resulted in a series of tsunamis this
caused hundred feet high waves and
devastated coastlines of 11 countries
naming indonesia india sri lanka and
thailand killing more than 2 lakh 30 000
people
there are many instances where tsunamis
have devastated many lives and property
but have you ever wondered how tsunami
occurs if you are curious to know this
then watch this video till the end also
at the end of the video we will share
some great tips on how you can survive a
tsunami so let's first see what is a
tsunami a tsunami is a series of very
long waves caused by sudden and large
displacement of the ocean basically
tsunamis are just larger versions of
regular waves so let's see how tsunamis
occur most tsunamis are caused by
earthquakes and so according to the
global historical tsunami database
around 80 percent of the tsunamis are
caused by earthquakes but tsunamis are
also caused by landslides
due to the volcanic activity and also
due to colliding of near-earth objects
like asteroids comets colliding or
exploding above the ocean thus a force
is created that radiates in all
directions away from its source
curious minds must be thinking can a
tsunami be predicted the answer is yes a
tsunami can be predicted the deep ocean
assessment and reporting of tsunamis
that is also called as dart is a system
used to predict tsunamis dart was
established by the national oceanic and
atmospheric administration on 3rd
october 1970 dart uses unique pressure
records that are installed at the bottom
of the ocean these recorders detect
slight changes in the water pressure
dart transmits this data to a ground
station by satellite via a surface view
thus predicting a tsunami also tsunamis
can be predicted by an earthquake if an
earthquake occurs in a location
specially the sea area then a tsunami is
likely to occur
so you must have heard the saying hope
for the best prepare for the worst and
so if you unfortunately get trapped in a
tsunami situation here are some tips on
how you can survive it number one first
thing to do in a tsunami situation is to
go to a higher ground because a tsunami
will first affect lower ground areas
also you can consider going on top of
your building with some essentials if
very less time is left with you and if
unfortunately you get trapped in a
tsunami try grabbing an object that
floats on water for example a wooden
object number two stay in the safe place
for at least eight hours when you find a
safe place consider staying there since
tsunami activity can continue for at
least eight hours
number three if you see downed power
lines then be away because if you come
in contact with it you can get
electrocuted number four stay away from
buildings and bridges since the depries
of these structures can kill you so now
you have all the answers on how and why
tsunamis occur and how to survive a
tsunami if you like this content share
