Tsunami. 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.

Tsunami Warning System MIDN 1/C Joseph Professor Avramov-Zamurovic ES DEC 2008

Waves Caused by wind, sun, and moon Do not move water laterally Transfer energy laterally Water moves in vertical circles Speeds of mph Wavelength of ft

Tsunami Phenomenon A very long wave Caused by an underwater earthquake or underwater volcanic eruption (epicenter) This disturbance has an incredible amount of force Energy dissipates away from the epicenter Speeds of mph Wavelength of 60 – 300 miles

Tsunami Phenomenon Cont. As the wave approaches land, it is pushed upward Principal region is Pacific Ocean Can occur in the Atlantic and Indian Ocean

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

NOAA and DART Stations NOAA - National Oceanic and Atmospheric Administrations Responsible for providing tsunami warnings to the Nation DART - Deep-ocean Assessment and Reporting of Tsunamis Station that detect tsunamis

DART System

DART Program

Objectives Build a system based off of the DART system that accurately detects the presence of a simulated tsunami Simulated tsunami is the longest wavelength wave that the Hydro Lab can create

Objectives Cont. Communicate the presence of a tsunami to a communications hub on the surface Explore the effect of turbulence on the force that arrives on shore Use environmental sensors to possibly detect the oxygen level of the water, amount of marine life activity, or the pH of the water

Hardware 3 Keller-America Acculevel Pressure Sensor ES 308 Board

Software Dynamic C To determine when the pressure is high enough for a tsunami Controls communication to the equipment on the surface Microsoft Excel / Matlab Generates plots of Pressure vs. Time

Current Status Built circuit Soldered extension cables Wrote C code Modified BNC Cable to talk to Hydro Lab equipment Obtained data at 10 different depths to calibrate the 3 sensors

Future Aspirations Build case to put in the bottom of the tank Obtain and configure communication equipment Conduct turbulence tests
