Coastal Christchurch and Banks Peninsula faces tsunami risk.
Local and regional source tsunami
Generated from a large earthquake around, or near, New Zealand. The chances of a local source tsunami is low however it is important to know that if one does happen you must evacuate immediately as you may only have a short time frame.
Distant source tsunami
Generated from a large earthquake a long distance away such as South America or Alaska. This is the biggest tsunami risk to the Christchurch coastline, however, there will be time to issue an official warning and several hours to evacuate areas at risk.
