The powerful Japan earthquake

Because one Tectonic plate was sliding under the other plate
 The  powerful Japan  earthquake shifted the earth's axis position
 Deforming it and  that  temblor already had caused Earth to rotate
 Faster than before when Hawaii reached these waves transmission.
                  
This temblor may have affected the length of the Earth’s days
So,each day may be quite two microseconds shorter than before.
Some parts of this country were moved  twelve  feet as scientists say,
The tremors sent a  monster  tsunami which slammed into the shore.

The aftershocks were rapidly continuing  without decreasing in frequency
While a rupture near the boundary between those tectonic plates occured.
Usually, the Pacific plate slowly  moves to  westwards at a very low velocity.
This quake was caused by Pacific and  American plates boundary rupture.


The dissipation of the heat from the mantle was a real source of energy
For Pacific plate thrusting underneath the Japan and  Eurasia plate.
This drive of plate tectonics was possible because of the excess density,
'Cause lithosphere became dense by cooling  until having a solid state.

The boundary between the Australian and Pacific tectonic plates
 Are part of the “Ring of Fire” and runs from south of Fiordland
 Along the line of the Southern Alps, beneath wonderful Cook Strait ,
 Capital of Wellington, and out to sea through the eastern North Island.

 A section of the prehistoric supercontinent Gondwana broke away
 Eighty million years ago comprising a few slithers of land left to drift
Coalescing into a new continent ,Zealandia,under the Southern sun's ray.
When magma heated continental crust above to crack open to form a rift .

Due to seismic activity,  sea levels  temporary fluctuated  looking so glum,
  Zealandia sank beneath sea level  letting New Zealand to be a remnant .
The pressure of opposing tectonic plates caused  the Alpine Fault to come.
 The Southern Alps rose above  the water looking like the moon's crescent.

Earth’s surface is recycled through the volcanic emission  and subduction.
The quake can be caused by a rupture near the boundary between plates.
The causes are high the level of carbone dioxide and sometimes erosion,
But when the rupture is big, it can become a real monstruous Hell's gate.

 The Pacific plate had thrusted underneath Japan and  in a late,
It dipped  beneath Eurasia plate and the earthquake occurred along
 The subduction zone at the interface between those two tectonic plates.
Two thousands people died because the earthquake was very strong.

The Pacific plate moves usually westwards at a very slow  velocity .
The boundary between the Pacific and  Australian Plate runs broadly
 Along  New Zealand ,where another quake occured with a strong ferocity,
While planet is on a one-way warming trend triggered by human activity.
