Had a few good aftershocks today, so we are always wondering if this means another big one is likely. After watching this newly aired video I was interested watching the shelf stuff falling inwards because it so strongly reminds me of how my office fell apart. All at once! Flung off my chair, I crawled under my desk for safety, never dreaming the building might collapse - the advice they give to drop and cover your head is very good - you really don't get time to run far, or safely, in the turmoil and many people were injured, or killed, by objects falling off the outer parapets, or glass and ceiling panels falling on them. The receptionist on the ground floor of the collapsing CTV building did manage to escape the building - in her case stopping would have resulted in her death. I guess in the split second you have to decide, some people will make the right choice, and some won't.... having a plan is a good idea, and it is why people in Christchurch have a habit of looking up, round and thinking where they are, and where they might be best to go, all the time!
