Tsunami from 1755 Lisbon earthquake. Computer model showing the energy map and wave amplitudes caused by the tsunami triggered by the 1755 Lisbon earthquake. The height of the waves are colour-coded: blue-to-green represents less than 30 centimetres, yellow-to-orange indicates 30 to 100 centimetres, light red-to-bright red indicates 1 to 3 metres, and dark red indicates greater than 3 metres. This powerful earthquake took place on 1 November 1755. The resulting damage, fire and tsunami caused the near total destruction of Lisbon, with an estimated 90,000 killed from a population of around 275,000. This image was produced using the Real-Time Forecasting of Tsunamis (RIFT) forecast model from the Pacific Tsunami Warning Center (PTWC).
