Tsunami in Cascadia, 1700, simulation

Videonummer 12082113
Tsunami in Cascadia, 1700. Real-Time Forecasting of Tsunamis (RIFT) 48-hour simulation of a tsunami originating in the Cascadian Subduction Zone of North America, January 26th 1700. Historical records describe a tsunami in Japan on 27th January 1700. Oral histories of Native Americans, sediment deposits, and forests of dead trees in the Pacific Northwest of North America indicate a huge earthquake in the region as the likely cause of the tsunami in Japan. RIFT takes earthquake information and calculates wave speed, wavelength, and amplitude, and shows what happens when the tsunami waves strike land. Wave height is indicated by colour, blue indicating no hazard and dark red indicating a severe hazard. At the end of the clip, the model also indicates maximum rise in sea levels across the ocean. This system is used by the Pacific Tsunami Warning Center to predict tsunamis and give warning for evacuation.
