PPT-Estimating Ocean Depth by Tsunami

Goals   Student analysis of real data reproduces 19 th century approach   Reinforce shallow water wave celerity and water depth   Student reasoning of how to do this analysis of tsunami routes.

Map modified from NOAA website: . http://. The name ‘tsunami’ is Japanese. . It means harbor wave. . Tsunamis used to be called tidal waves, but they actually have nothing to do with the tides.. The sudden displacement of huge amounts of water causes tsunamis. . Tsunami Mathematics. Mathematically there are three different but related factors involved in . relation . to a Tsunami.. These are SPEED, HEIGHT, and ENERGY POWER. . Tsunami Mathematics - SPEED. In the open Ocean the speed of a Tsunami is approximately: . Waves part 2. Tsunami. Tsunami terminology. Japanese term meaning “. harbour. wave”. Also called “seismic sea waves”. Created by movement of the ocean floor by:. Underwater fault movement. Underwater avalanches. Earthquake Risk. Earthquakes are likely wherever plate movement stores energy in the rock along faults.. Geologists can determine earthquake risk by locating where faults are active and where past earthquakes have occurred.. Inundation Mapping . for Alaska Coastal . Communities.
