How do you prepare for a major earthquake?

The massive Alpine Fault is due for another big earthquake and scientists have been drawing up a scenario of what the devastation would look like. They are part of Project AF8, a South Island-wide effort to plan and prepare for at least a magnitude 8. 8000 years of geologicial data shows there's a severe rupture every 300 years - the last one was in 1717. We spoke to Otago University's Caroline Orchiston who is the lead scientists for Project AF8.
