Miss Mole has written on her Facebook page "City … you should see it … everyone is safe and okay … But or city is in ruins!"

"Life is strange. One minute I'm at a party … the next … I'm in bed … next I'm running outta my unit … as it's crashing around … all in a few minutes … life is changed.

"My best friends here are all okay … and that's the most important thing … but I'll never forget running out of my house … as it's about to come down!"

Christchurch Mayor Bob Parker says there will not be a house or family in the city that has not in some way had damage done to them or their property.

"Our thoughts are with our people.We know that a lot of people will be very nervous, deeply disturbed."
