2011 Japanese Earthquake and Tsunami
On Friday 11th March at 2.46 (their time) an
earthquake struck Japan with a magnitude of 8.9.
It is the largest in Japan, since seismology
records began in 1900. It was also the fourth
largest earthquake to occur in the world. Over five
hundred aftershocks of magnitude 4.5 or greater
have occurred since the initial quake. Sendai was
the closest city to the epicentre and received a lot
of damage. There have been many effects locally
and globally from this natural disaster.
How it happened
Japan lies where three tectonic plates
meet. The Eurasian Plate, the Pacific
Plate and the Philippine Plate. So,
therefore is very prone to tectonic activity
and its negative effects. The Pacific plate
is being forced under the Eurasian one
and as it does it does not go smoothly.
As this happens the pressure builds up
and suddenly there is a subduction earthquake. Earthquakes take
place daily in Japan, as the plate moves, but unfortunately this one
was much more disastrous.
How the Tsunami was formed:
The water above the ocean bed
deforms and misplacing a large amount
of water from its original position.
Waves are then created because of
such loss of water mass in one
particular spot which happens against
the laws of gravity if this sudden
movement is harsh enough, it can

Here's a taster:

Subduction earthquakes are particularly
effective in generating tsunamis. The Tsunami formed by Japans
earthquake hit Hawaii, the US and other places on the Pacific Island
Primary Effects:
Some primary effects of the earthquake included
With thousands missing or injured and 10,000 dead (expected
result), this disaster will not be the worst in history but still
catastrophic. These statistics will continue to rise as more are
reported and the results will be catastrophic.
Despite the usual primary effect of building failure.…read more

Nuclear Power Station caused one of the buildings to crumble
to the ground. The cooling system at the reactor failed shortly
after the earthquake. Officials feared that a meltdown may
occur, and radioactive material was detected outside the
plant. As Japans main source of energy comes from nuclear
there are a lot of stations and this disaster has caused a lot of
worried. As a result many people of Japan have digested too
much radio activeness in the air, which could result in more
deaths.…read more

It is also one of the worlds biggest export countries that
provides for the whole worlds economy. Being so successful it
was also one of the richest. The disaster will be excremental
to the countries exporting capabilities and will affect the
world's economy also.
Due to the Tsunami, the grounds of Japan will be ruined and
probably unusable for many years to come. This will stop the
growth of rice which is one of the most bought and eaten food
in Japan.…read more
