2. Have you ever wondered
why tsunamis happen? In
this presentation we’ll give
you the facts about these
huge waves, so you can
better understand what
causes a tsunami.
The name tsunami,
pronounced soo-nahm-ee
comes from two Japanese
words; tsu means harbor
and nami meaning wave, so
tsunami means
harbor-wave.
5. Earthquake
most tsunamis are caused by submarine
earthquakes but not all submarine earthquakes
cause tsunamis. Movement on the fault must
have a vertical component that generates
sufficient displacement to set a tsunami running
6. Volcanic Eruption
a volcanic eruption or explosion- submarine
explosions, caldera collapse and massive
pyroclastic flows can all cause sufficient
displacement of water to generate a tsunami.
7. Landslide
underwater landslides or coastal landslides that
fall into the ocean can displace enough water to
create a tsunami. Sometimes the landslides are
caused by earthquakes.
8. Meteor Impact
large meteorites have a high probability of
landing in the ocean and causing a tsunami
given that about two thirds of the surface of the
Earth is covered by water.
9. A tsunami is caused when there is a disturbance deep under
the ocean such as an earthquake, volcano or a landslide. An
underwater earthquake is the most common cause for a tsunami,
but not just any underwater earthquake causes a tsunami. The
earthquake needs to be a large enough earthquake of around 7.0
magnitude or bigger.
Underwater earthquakes happen because oceanic and
continental plates, which are huge areas of the earth’s crust, push
into each other and build up pressure. The pressure builds and
builds until eventually the oceanic plate slips under the continental
plate releasing all that pressure and energy in the form of an
earthquake.
If an underwater earthquake is large enough, the ocean
floor will make significant movements, therefore the water above
the sea floor must move too.
