Earth Quake Damages
about 100,000 thousand building were damaged from the earthquake and its aftershocks and around 8000-10000 building needed to be demolished.
How a Earthquake is caused
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little.
What occurred
on 22 February 2011 Christchurch suffered a 6.3 magnitude earthquake.The Earthquake was centered 10km south east of the city at a depth of 4.5-5km.After the main quake 10 aftershocks came with magnitudes of 4-4.5 making this one of New Zealand worst earthquakes or they worst the country has suffered.
Death Count and Injuries
185 people were killed during the earthquake and thousand injured buried under tones of ruble rescue teams went out searching for people finding many people trapped and pinned down by pieces of fallen concrete.
Christchurch Split up
Christchurch was split up into 4 zones/sections after the Earthquake the Green Zone was a safe stable place,the Orange Zone was a uncertain place it was not ready for building layouts and to be rebuilt on as it needed more checks,The Red Zone was a unstable unsafe place not to be built on and building could collapse,the white zone was a unchecked place and was uncertain of its stability.

Cost of The
Earth Quake
In the central city alone, more than 1,000 buildings have been demolished. In residential areas, 7,400 properties were red-zoned and sold to the Crown. Just over 6,000 houses have been cleared from those properties. As the rebuild continues, nearly 29,000 building permits have been granted, with a total value of $6.6 billion. There's also roads, bridges, underground pipes and cables. The estimated cost of those is just under $2 billion. The rebuild team calculates it's only 65% through the work.
The total cost to insurers of rebuilding was originally estimated at $15 billion. At that point it was already predicted to be by far New Zealand's costliest natural disaster, and the third-costliest earthquake worldwide.
