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 peopleDecember 2004
Tsunami

11. 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

12. OBJECTIVES
 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

13. HARDWARE & SOFTWARE

14. 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
up heights , threat zones , etc) for the entire the
Indian Ocean
