Tsunami warning system

A tsunami warning system (TWS) is used to detect tsunamis in advance and issue warnings to prevent loss of life and damage. It is made up of two equally important components: a network of sensors to detect tsunamis and a communications infrastructure to issue timely alarms to permit evacuation of the coastal areas

3. Introduction A  tsunami warning system  ( TWS ) is used to detect tsunamis in advance and issue warnings to prevent loss of life and damage. It is made up of two equally important components: a network of sensors to detect tsunamis and a communications infrastructure to issue timely alarms to permit evacuation of the coastal areas. There are two distinct types of tsunami warning systems:  international  and  regional

4. What is Tsunami The displacement of an equivalent volume of water generates the tsunami A tsunami is very long ocean wave generated by sudden displacement of the sea floor or of the oceanic mass

5. Waves Caused by wind , sun, and moon Do not move water laterally Transfer energy laterally Water moves in vertical circles Speeds of 5 -60 mph Wavelength of 300 – 600ft

6. Tsunami Phenomenon A very long caused by an underwater earthquake or underwater volcanic eruption This disturbance has an incredible amount of force Speed is around 500 – 600 mph Wavelength of 60 – 300 miles

7. NOAA & DART station NOAA Responsible for providing tsunami warnings to the nation DART station that detect tsunamis

8. In December 2004 Tsunami Earthquake in Indian Ocean Rupture was ~1000 miles long Hit India , Thailand , Malaysia , Indonesia many Island & Africa Killed 200,000+ people Displaced 1.6 million people December 2004 Tsunami

9. ADVANTAGES & DISADVANTAGES 1. ADVANTAGES Deep water pressure produces relatively low false-position as wind driven waves do not generate deep pressure differentials Good advance warning 2. DISADVANTAGES More expensive Need multiple sensors

10. O bjectives Build a system based off of the DART system that accurately detects the presence of a simulated tsunamis Simulated tsunami is longest wavelength wave that Hydro lab can create

11. HARDWARE & SOFTWARE Hardware 3Keller-America Acculevel pressure sensor ES 308 board Software Dynamic C Microsoft Excel/ matlab

12. Conclusion Geospatial tech has immensely helped in the design of early warning system for tsunami. The system is capable of providing tsunamis advisories (earthquake information estimated travel time, run u p heights , threat zones , etc) for the entire the Indian Ocean
