These are some places tsunims occurs
The SWASH (Simulating Waves until at Shore) model sounds like something that would have been useful in predicting the tsunami in Japan. According to the developer Marcel Zijlema at Delft University of Technology, it quickly calculates how tall a wave is, how fast it’s moving, and how much energy it holds. Yet, Zijlema admits that unfortunately it wouldn’t have helped in this case. “The quake was 130 kilometers away, too close to the coast, and the wave was moving at 800 kilometers per hour. There was no way to help. But at a greater distance the system could literally save lives.”
SWASH is a development of the SWAN (Simulating Waves Near SHore), which has been around since 1993 and is used by over 1,000 institutions around the world. SWAN calculates wave heights and wave speeds generated by wind and can also analyze waves generated elsewhere by a distant storm. The program can be run on an ordinary computer and the software is free.
An oceanographer is a person who studies oceanographer which includes the study of tsunamis and hurricanes.
Back then tsunamis were hard to predict but now it is much easier.
