Just to let people know, a number of pastors in chch got together about this and believe its totally incorrect so even from that point the churches don't believe it, if that helps peoples nerves.
If you can, I wouldn't worry about it, from people who know, the lady who started it is a bit weird. I notice her prediction talks about Christchurch and Kaiapoi etc being hit but it will apparently conveniently miss her house in Amberly. Go figure
