There has been extensive seismic activity in New Zealand over the last few years. In November there was another significant earthquake in the South Bay Marina, on the South Island.
The South Bay Marina and surrounding area in Kaikoura is a popular area for tourism and commercial fishing. However the earthquake has disrupted this activity with seabed uplift.
Areas that were previously channels for fishing or tourism boats to make their way into open water are now reduced to narrow passages, only usable at high tide.
Eliot Sinclair were approached to survey the damage after the earthquake and to re-establish chart datum.
Liam Jagvik from Eliot Sinclair talks with Derek Shanks from Trimble Christchurch in this 30 minute webinar.
