All About Earthquakes By: Brian Kraft and Adam Morton

How Do Earthquakes Occur Built up stress in the crust causes the plates to scrape and shake earth. This releases waves through the crust and causes shaking.

Where Do They Occur? Most of the time earthquakes occur along plate boundaries. Deeper parts of the earth cause the crust to move New Zealand has a lot of earthquakes because it is along a plate boundary

Christchurch The earthquake hit on February 22 nd at 1:24 pm The epicenter was in Darfield New Zealand, a town a few miles from Christchurch There was two billion New Zealand dollars worth of damage About 7500 buildings were destroyed AfterBefore

Christchurch There were 65 people confirmed dead in Christchurch There are still fifty people missing The Prime Minister John Key said "may well be New Zealand's darkest day". Nothing could have been done to stop this earthquake because they had no idea it was coming

Efforts Immediately after the earthquake survivors were being rescued from the ruble Sniffer dogs were brought in to help search for people Helicopters sent down straps and hooks to rescue people that were stranded on roof tops

Effects on Humans Many buildings in Christchurch collapsed or were damaged Also many faults opened up in the streets which can be very dangerous Another danger is liquefying Liquefying is when the ground turns to mud sucks everything down into the ground
