Document Summary
Tsunami: a long high sea wave caused by an earthquake, submarine landslide, other disturbance. Rouge wave (killer wave): large, unexpected and suddenly appearing surface waves, rare. Movement on the sea floor of the earth"s crust up or along a fault. Stages: initiation: earthquakes, split: when the waves move apart from each other, amplification: tsunami hits the shore and comes back, run up: wave goes over the shore. Distant tsunami: originates form a distant source (more than 1000km away, 3 hours travel from area of interest) Local tsunami: nearby source which its destructive effects are candied to coasts within. Movement of large material into lake or ocean. Forces exerted by flooding and receding waves. Release of materials such as gas and chemicals as things are ruptured. Inundation maps based on modelling of coastal processes, predict and display the extent that waves will run up shoreline: developed by historical records and geological data that indicates info on tsunami frequency and size.
