NIWA survey work helps assess Kaikoura tsunami risks

Surveying work carried out by NIWA scientists this week is helping provide new insights into the tsunami risk from undersea landslides in the Kaikoura Canyon.

Submarine landslides are one of the main processes that create submarine canyons. Landslides in the head of Kaikoura Canyon are thought to occur about once every 200 years on average.
