1717's Alpine Fault rupture moved from south to north, with a 75% chance of major earthquake in Canterbury and Marlborough within 50 years.

Researchers have determined that the last major rupture of New Zealand's Alpine Fault in 1717 moved from south to north. This finding is significant as it informs preparations for future earthquakes, with a 75% chance of a major event in the next 50 years. While the Fiordland area may be less affected, populated regions like Canterbury and Marlborough could experience intense shaking. The study's methodology can also apply to other global fault lines.
