Ben Douglas-Clifford: "I was at St Andrew's College. The shake was very violent - there were no injuries at my school but we had to evacuate to the main field. This muddy water process called liquefaction spurted up through the ground and paths, so we had to wait for an all-clear."

Anna Walker: "As you get nearer the beach the ground is less stable because Christchurch was built on old swampland, so out here where my flat is the roads are a mess. I feel incredibly lucky that my family are OK. It all feels pretty surreal."
Sarah Gosling, who was at work when the earthquake hit, said: "The building in the photo is the Canterbury TV building on the corner of Madras and Cashel Street, Christchurch. I was thrown around as I tried to get under my desk."

Patrick Todd, a civil engineer working on the rebuild from the original earthquake, said: "We've had several aftershocks and all the phone networks are jammed."

Sam McLeod says the earthquake has caused mass devastation to a large number of homes and building even quite a distance out of the Central Business District.
