Shocks from the 1755 Lisbon Earthquake are…
November 1755 CE
Tsunamis as tall as twenty meters (sixty-six feet) sweep the coast of North Africa, and strike Martinique and Barbados across the Atlantic.
A three-meter (ten-foot) tsunami hits Cornwall on the southern English coast. Galway, on the west coast of Ireland, is also hit, resulting in partial destruction of the "Spanish Arch" section of the city wall.
At Kinsale, several vessels are whirled round in the harbor, and water pours into the marketplace.
In 2015, it will be revealed that the tsunami waves may have reached the coast of Brazil, then a colony of Portugal.
Such a hypothesis will be raised by reviewing letters sent by Brazilian authorities at the time of the earthquake. These letters describe damage and destruction caused by gigantic waves.
