New Zealand Historical Tsunami Database

New Zealand Tsunami Database includes information about tsunamis that have reached the coastline of New Zealand since humans arrived in this land until the present day. The database is primarily the work of historical seismologist Gaye Downes working for GNS Science who collected reports of tsunamis around New Zealand and, in many cases, carried out research to determine parameters of the source, travel time and impact associated with each event. Reports of tsunamis that make up the core of this database come from tide gauges, newspaper articles, harbour masters, records from ships, personal diary entries and Māori oral records. This primary source material is summarised in the database and complete transcriptions are held by the database custodian. DOI: Cite as: GNS Science. (2020).
