Chile, officially the Republic of Chile, is a country located in western South America. It is the southernmost country in the world and closest to Antarctica, stretching along a narrow strip of land between the Andes Mountains and the Pacific Ocean. With an area of 756,096 square kilometers (291,930 sq mi) and a population of 17.5 million as of 2017, Chile shares borders with Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage to the south. The country also controls several Pacific islands, including Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island, and claims about 1,250,000 square kilometers (480,000 sq mi) of Antarctica as the Chilean Antarctic Territory. The capital and largest city of Chile is Santiago, and the national language is Spanish.

New Zealand is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island and the South Island —and over 700 smaller islands. It is the sixth-largest island country by area, covering 268,021 square kilometres (103,500 sq mi). New Zealand is about 2,000 kilometres (1,200 mi) east of Australia across the Tasman Sea and 1,000 kilometres (600 mi) south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland.

The Menai Strait is a narrow stretch of shallow tidal water about 25 km (16 mi) long, which separates the island of Anglesey from the mainland of Wales. It varies in width from 400 metres (1,300 ft) from Fort Belan to Abermenai Point to 1,100 metres (3,600 ft) from Traeth Gwyllt to Caernarfon Castle. It then narrows to 500 metres (1,600 ft) in the middle reaches and then it broadens again. At Bangor, Garth Pier, it is 900 metres (3,000 ft) wide. It then widens out, and the distance from Puffin Island to Penmaenmawr is about 8 kilometres (5.0 mi).

Ostrea edulis, commonly known as the European flat oyster, is a species of oyster native to Europe. In Britain and Ireland, regional names include Colchester native oyster, mud oyster, or edible oyster. In France, Ostrea edulis are known as huîtres plates except for those that come from the Belon River estuary in Brittany, France, which are known as Belons.

An invasive or alien species is an introduced species to an environment that becomes overpopulated and harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food web – for example the purple sea urchin which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter. Since the 20th century, invasive species have become a serious economic, social, and environmental threat.

The Foveaux Strait, separates Stewart Island, New Zealand's third largest island, from the South Island. The strait is about 130 km long, and it widens and deepens from east to west. The strait lies within the continental shelf area of New Zealand, and was probably dry land during the Pleistocene epoch.

The resulting tsunamis affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands.
