The tsunami catalogues of the Atlantic include two transatlantic tsunamis in the 18th century the extensively studied 1st November 1755, and 31st March 1761. The latest event struck Portugal, Spain, and Morocco around noontime. Several sources report a tsunami following the earthquake as far as Cornwall (United Kingdom), Cork (Ireland) and Barbados (Caribbean).

Māori oral histories from the northern South Island of Aotearoa – New Zealand provide details of ancestral experience with tsunamis. Exchanges with key informants from the Māori kin groups of Ngāti Koata and Ngāti Kuia reveal that these histories, recorded in a narrative form, are not merely another source of information about past catastrophic saltwater inundations but, rather, reference multiple layers of experience and meaning, from memorials to ancestral figures and their accomplishments, to claims about place, authority and knowledge.
