Day of The Tsunami - Page Text Content

BC: This book was created to inform those affected by the 2004 Indian Ocean Tsunami why and how this happened to them and what is being developed to make sure fewer casualties are associated with tsunamis.

FC: Day of the Tsunami

1: On December 26, 2004, the worst tsunami in modern records occurred, at a magnitude of 9.2.

2: The epicenter of the earthquake was in the Indian Ocean to the west of Indonesia. 230,000 people were killed in 11 different countries and 170,000 deaths occurred in Indonesia alone.

3: Tsunamis form due to seismic movement in the ocean floor. Tsunamis most commonly occur during underwater landslides, submarine earthquakes, volcanic eruptions, and meteorite impacts.

4: In deep water a tsunami is 16 inches or less in height and travels from 300 to 600 mph. As the water gets shallower the bottom of the wave meets the ocean floor, causing it to rise. This slows the wave to 49 mph.

5: The 2004 Indian Ocean tsunami hurt this area in many ways. It cost 10 billion dollars to clean up the destruction. It destroys railroads, bridges, roads, and anything in its path.

6: This tsunami also caused some food and water shortages and the rapid spread of diseases. This tsunami also hurt the fishing economy that some are dependent upon. It also hurt tourism which can be a big source of income for a country.

8: Very recently there has been new technology helping predict when and where a tsunami will strike. A new system named DART (the Deep-Ocean Assessment and Reporting of Tsunamis) has been developed.

9: DART includes six research centers with new sophisticated computer models. DART also includes 25 buoys in the Pacific Ocean, 6 buoys in the Atlantic Ocean, and surface and coastal weather stations.

11: At each DART weather station there are bottom pressure recorders. These instruments are placed on the sea floor and can measure tsunami waves at a precision of 1 millimeter. This info is transmitted back to the forecasting station where it is plugged into a computer that predicts how the wave will behave across the ocean, leaving more time for evacuation so less death will result.
