It was a year ago sitting in the same chair, I watched the reports on Newsworld. The numbers dead increasing on every report. The waves were caused by a 9.0 earthquake, the largest in recorded history, so powerful it knock the earth off kilter. The planet now wobbles 2cm off kilter and spins slighty faster.

The link is to the Nova episode I just watched that explained all that happened, from the perspective of the men who worked in the early warning Tsunamai centre in Hawaii who monitor the Pacific. There was no such warning systems in the Indian ocean, a region well known for large quakes and tsunamai.

Half a Millon people homeless, almost 300,000 dead,this was the deadliest natural disaster in modern times. As the date of September 11th will resonant for years, Boxing day will have a somber reminder for years to come.
