Quake threat: Calls for buildings on Alpine Fault to be moved

There are calls for Franz Josef emergency service buildings on top of the Alpine fault to be urgently moved after research has shown the probability of a devastating quake striking the South Island over the next 50 years has more than doubled.

The study suggests a big quake could block South Island highways in more than 120 places, leave 10,000 people cut off, and cost the economy about $10 billion.
