Tsunamis affecting New Zealand are mainly due to the country being part of the geologically active Pacific Plate and associated with the Pacific Ring of Fire. Tsunamis affect New Zealand's coastline reasonably frequently and tend to be caused by earthquakes on the Pacific Plate both locally and as far away as South America, Japan, and Alaska. Some have been attributed to undersea landslides, volcanoes, and at least one meteor strike. New Zealand is affected by at least one tsunami with the a wave height greater than one metre every ten years on average. The history of tsunamis is limited by the country's written history only dating from the early to mid-1800s with Maori oral traditions and paleotsunami research prior to that time. Studies are also being carried out into possible tsunamis on the larger inland lakes, particularly from landslides.
